(k) Care must be taken when jacking up and supporting the
vehicle. Be sure to lift and support the vehicle at the prop-
er locations (See page IN--9).
S Cancel the parking brake on the level place and
shift the transmission in Neutral (or N range).
S When jacking up the front wheels of the vehicle, at
first place stoppers behind the rear wheels.
S When jacking up the rear wheels of the vehicle, at
first place stopper before the front wheels.
S When either the front or rear wheels only should be
jacked up, set rigid racks and place stoppers in front
and behind the other wheels on the ground.
S After the vehicle is jacked up, be sure to support it
on rigid racks. It is extremely dangerous to do any
work on a vehicle raised on a jack alone, even for
a small job that can be finished quickly.
(l) Observe the following precautions to avoid damage to the
following parts:
(1) Do not open the cover or case of the ECU unless
absolutely necessary. (If the IC terminals are
touched, the IC may be destroyed by static electric-
ity.)
(2) To disconnect vacuum hoses, pull off the end, not
the middle of the hose.
(3) To pull apart electrical connectors, pull on the con-
nector itself, not the wires.
(4) Be careful not to drop electrical components, such
as sensors or relays. If they are dropped on a hard
floor, they should be replaced and not reused.
(5) When steam cleaning an engine, protect the elec-
tronic components, air filter and emission--related
components from water.
(6) Never use an impact wrench to remove or install
temperature switches or temperature sensors.

INTRODUCTION REPAIR INSTRUCTIONS
(7) When checking continuity at the wire connector, in-
sert the tester probe carefully to prevent terminals
from bending.
(8) When using a vacuum gauge, never force the hose
onto a connector that is too large. Use a step--down
adapter for adjustment. Once the hose has been
stretched, it may leak air.
(m) Installation and removal of vacuum hose:
(1) When disconnecting vacuum hoses, use tags to
identify where they should be reconnected to.
(2) After completing a job, double check that the vacu-
um hoses are properly connected. A label under the
hood shows the proper layout.
(n) Unless otherwise stated, all resistance is measured at an
ambient temperature of 20˚C (68˚F). Because the resis-
tance may be outside specifications if measured at high
temperatures immediately after the vehicle has been run-
ning, measurement should be made when the engine has
cooled down.

INTRODUCTION FOR ALL OF VEHICLES
FOR ALL OF VEHICLES
PRECAUTION
1. FOR VEHICLES EQUIPPED WITH SRS AIRBAG AND
SEAT BELT PRETENSIONER
(a) The HILUX is equipped with an SRS (Supplemental Re-
straint System), such as the driver airbag, front passen-
ger airbag assembly and seat belt pretensioners.
Failure to carry out service operations in the correct se-
quence could cause the supplemental restraint system to
unexpectedly deploy during servicing, possibly leading to
a serious accident.
Further, if a mistake is made in servicing the supplemental
restraint system, it is possible the SRS may fail to operate
when required. Before servicing (including removal or
installation of parts, inspection or replacement), be sure
to read the following items carefully, then follow the cor-
rect procedure described in this manual.
(b) GENERAL NOTICE
(1) Malfunction symptoms of the supplemental re-
straint system are difficult to confirm, so the diag-
nostic trouble codes become the most important
source of information when troubleshooting. When
troubleshooting the supplemental restraint system,
always inspect the diagnostic trouble codes before
disconnecting the negative (--) terminal cable from
the battery (See page DI--3).
(2) Work must be started after 90 seconds from the
time the ignition switch is turned to the ”LOCK” posi-
tion and the negative (--) terminal cable is discon-
nected from the battery.
(The supplemental restraint system is equipped
with a back--up power source so that if work is
started within 90 seconds of disconnecting the neg-
ative (--) terminal cable from the battery, the SRS
may deploy.)
When the negative (--) terminal cable is discon-
nected from the battery, memory of the clock and
audio systems will be cancelled. So before starting
work, make a record of the contents memorized by
the each memory system. Then when work is fin-
ished, reset the clock and audio systems as before.
To avoid erasing the memory of each memory sys-
tem, neveruse a back--up powersupply fromanoth-
er battery.

(3) Even in cases of a minor collision where the SRS
does not deploy, the steering wheel pad, front pas-
senger airbag assembly and seat belt pretension-
ers should be inspected (See Pub. No. RM585E).
(4) Never use SRS parts from another vehicle. When
replacing parts, replace them with new parts.
(5) Before repairs, remove the airbag sensor if shocks
are likely to be attached to the sensor during re-
pairs.
(6) Never disassemble and repair the airbag sensoras-
sembly, steering wheel pad, front passenger airbag
assembly or seat belt pretensioner.
(7) If the airbag sensor assembly, steering wheel pad,
front passenger airbag assembly or seat belt pre-
tensioner has been dropped, or if there are cracks,
dents or other defects in the case, bracket or con-
nector, replace them with new ones.
(8) Do not directly expose the airbag sensor assembly,
steering wheel pad, front passenger airbag assem-
bly or seat belt pretensioner to hot air or flames.
(9) Use a volt/ohmmeter with high impedance (10 kΩ/V
minimum) for troubleshooting of the electrical cir-
cuit.
(10) Information labels are attached to the periphery of
the SRS components. Follow the instructions on the
notices.
(11) After work is completed, check the SRS warning
light for the supplemental restraint system (See
page DI--3).
(c) SPIRAL CABLE (in Combination Switch)
The steering wheel must be fitted correctly to the steering
column with the spiral cable at the neutral position, other-
wise cable disconnection and other troubles may result.
Refer to SR--26 on Pub. No. RM585E concerning correct
steering wheel installation.

INTRODUCTION FOR ALL OF VEHICLES
(d) STEERING WHEEL PAD (with Airbag)
(1) When removing the steering wheel pad or handling
a new steering wheel pad, it should be placed with
the pad top surface facing up.
Storing the pad with its metallic surface facing up-
ward may lead to a serious accident if the airbag in-
flates for same reason. In addition do not store a
steering wheel pad on top of another one.
(2) Never measure the resistance of the airbag squib.
(This may cause the airbag to deploy, which is very
dangerous.)
(3) Grease should not be applied to the steering wheel
pad and the pad should not be cleaned with deter-
gents of any kind.
(4) Store the steering wheel pad where the ambient
temperature remains below 93˚C (200˚F), without
high humidity and away from electrical noise.
(5) When using electric welding, first disconnect the air-
bag connector (yellow color and 2 pins) under the
steering column near the combination switch con-
nector before starting work.
(6) When disposing of a vehicle or the steering wheel
pad alone, the airbag should be deployed using an
SST before disposal (See page RS--13).
Carry out the operation in a safe place away from
electrical noise.

(e) FRONT PASSENGER AIRBAG ASSEMBLY
(1) Always store a removed or new front passenger air-
bag assembly with the airbag deployment direction
facing up.
Storing the airbag assembly with the airbag deploy-
ment direction facing down could cause a serious
accident if the airbag deploys.
(2) Never measure the resistance of the airbag squib.
(This may cause the airbag to deploy, which is very
dangerous.)
(3) Grease should not be applied to the front passen-
ger airbag assembly and the airbag door should not
be cleaned with detergents of any kind.
(4) Store the airbag assembly where the ambient tem-
perature remains below 93˚C (200˚F), without high
humidity and away from electrical noise.
(5) When using electric welding, first disconnect the air-
bag connector (yellow color and 2 pins) installed on
the assembly before starting work.
(6) When disposing of a vehicle or the airbag assembly
alone, the airbag should be deployed using an SST
before disposal (See Pub. No. RM585E on page
RS--25).
Perform the operation in a safe place away from
electrical noise.

INTRODUCTION FOR ALL OF VEHICLES
(f) SEAT BELT PRETENSIONER
(1) Never measure the resistance of the seat belt pre-
tensioner. (This may cause the seat belt pretension-
er to activate, which is very dangerous.)
(2) Never disassemble the seat belt pretensioner.
(3) Never install the seat belt pretensioner in another
vehicle.
(4) Store the seat belt pretensioner where the ambient
temperature remains below 80˚C (176˚F) and
away from electrical noise without high humidity.
(5) When using electric welding, first disconnect the
connector (yellow color and 2 pins) before starting
work.
(6) When disposing of a vehicle or the seat belt preten-
sioner alone, the seat belt pretensioner should be
activated before disposal (See Pub. No. RM585E
on page BO--137). Perform the operation in a safe
place away from electrical noise.
(7) The seat belt pretensioner is hot after activation, so
let it cool down sufficiently before the disposal.
However never apply water to the seat belt preten-
sioner.
(g) AIRBAG SENSOR ASSEMBLY
(1) Never reuse the airbag sensor assembly involved
in a collision when the SRS has deployed.
(2) The connectors to the airbag sensor assembly
should be connected or disconnected with the sen-
sor mounted on the floor. If the connectors are con-
nected or disconnected while the airbag sensor as-
sembly is not mounted to the floor, it could cause
undesired deployment of the supplemental re-
straint system.
(3) Work must be started after 90 seconds from the
time the ignition switch is turned to the ”LOCK” posi-
tion and the negative (--) terminal cable is discon-
nected from the battery, even if only loosing the set
bolts of the airbag sensor assembly.
(h) WIRE HARNESS AND CONNECTOR
The SRS wire harness is integrated with the instrument
panel wire harness assembly. All the connectors in the
system are a standard yellow color. If the SRS wire har-
ness becomes disconnected or the connector becomes
broken due to an accident, etc., repair or replace it.

HOW TO TROUBLESHOOT ECU CONTROLLED SYSTEMS
GENERAL INFORMATION
A large number of ECU controlled systems are used in the HILUX. In general, the ECU controlled system
is considered to be a very intricate system requiring a high level of technical knowledge and expert skill to
troubleshoot. However, the fact is that if you proceed to inspect the circuits one by one, troubleshooting of
these systems is not complex. If you have adequate understanding of the system and a basic knowledge
of electricity, accurate diagnosis and necessary repair can be performed to locate and fix the problem. This
manual is designed through emphasis of the above standpoint to help service technicians perform accurate
and effective troubleshooting, and is compiled for the following major ECU controlled systems:
The troubleshooting procedure and how to make use of it are described on the following pages.

FOR USING HAND-
-HELD TESTER
S Before using the tester, the tester’s operator manual should be read thoroughly.
S If the tester cannot communicate with ECU controlled systems when you have connected the cable
of the tester to DLC3, turned the ignition switch ON and operated the tester, there is a problem on the
vehicle side or tester side.
(1) If communication is normalwhen the tester is connected to another vehicle, inspect the diagnosis
data link line (Busline) or ECU power circuit of the vehicle.
(2) If communication is still not possible when the tester is connected to another vehicle, the problem
is probably in the tester itself, so perform the Self Test procedures outline in the Tester Operator’s
Manual.

1. CUSTOMER PROBLEM ANALYSIS
In troubleshooting, the problem symptoms must be confirmed accurately and all preconceptions must be
cleared away in order to give an accurate judgment. To ascertain just what the problem symptoms are, it is
extremely important to ask the customer about the problem and the conditions at the time it occurred.
Important Point in the Problem Analysis:
The following 5 items are important points in the problem analysis. Past problems which are thought to be
unrelated and the repairhistory, etc. may also help in some cases, so as much information as possible should
be gathered and its relationship with the problem symptoms should be correctly ascertained for reference
in troubleshooting. A customer problem analysis table is provided in Diagnostics section for each system
for your use.

2. SYMPTOM CONFIRMATION AND DIAGNOSTIC TROUBLE CODE CHECK
The diagnostic system in the HILUX fulfills various functions. The first function is the Diagnostic Trouble
Code Check in which a malfunction in the signal circuits to the ECU is stored in code in the ECU memory
at the time of occurrence, to be output by the technician during troubleshooting. Another function is the Input
Signal Check which checks if the signals from various switches are sent to the ECU correctly.
By using these check functions, the problem areas can be narrowed down quickly and troubleshooting can
be performed effectively. Diagnostic functions are incorporated in the following systems in the HILUX.

In diagnostic trouble code check, it is very important to determine whether the problem indicated by the diag-
nostic trouble code is still occurring or occurred in the past but returned to normal at present. In addition,
it must be checked in the problem symptom check whether the malfunction indicated by the diagnostic
trouble code is directly related to the problem symptom or not. For this reason, the diagnostic trouble codes
should be checked before and after the symptom confirmation to determine the current conditions, as shown
in the table below. If this is not done, it may, depending on the case, result in unnecessary troubleshooting
for normally operating systems, thus making it more difficult to locate the problem, or in repairs not pertinent
to the problem. Therefore, always follow the procedure in correct order and perform the diagnostic trouble
code check.

3. SYMPTOM SIMULATION
The most difficult case in troubleshooting is when there are no problem symptoms occurring. In such cases,
a thorough customer problem analysis must be carried out, then simulate the same or similar conditions and
environment in which the problem occurred in the customer’s vehicle. No matter how much experience a
technician has, or how skilled he may be, if he proceeds to troubleshoot without confirming the problem
symptoms he will tend to overlook something important in the repair operation and make a wrong guess
somewhere, which will only lead to a standstill. For example, for a problem which only occurs when the en-
gine is cold, or for a problem which occurs due to vibration caused by the road during driving, etc., the prob-
lem can never be determined so long as the symptoms are confirmed with the engine hot condition or the
vehicle at a standstill. Since vibration, heat or water penetration (moisture) is likely cause for problem which
is difficult to reproduce, the symptom simulation tests introduced here are effective measures in that the ex-
ternal causes are applied to the vehicle in a stopped condition.
Important Points in the Symptom Simulation Test:
In the symptom simulation test, the problem symptoms should of course be confirmed, but the problem area
or parts must also be found out. To do this, narrow down the possible problem circuits according to the symp-
toms before starting this test and connect a tester beforehand. After that, carry out the symptom simulation
test, judging whether the circuit being tested is defective or normal and also confirming the problem symp-
toms at the same time. Refer to the problem symptoms table for each system to narrow down the possible
causes of the symptom.

HOW TO USE THE DIAGNOSTIC
CHART AND INSPECTION
PROCEDURE
1. CONNECTOR CONNECTION AND TERMINAL IN-
SPECTION
S For troubleshooting, diagnostic trouble code charts or
problem symptom table are provided for each circuit with
detailed inspection procedures on the following pages.
S When all the component parts, wire harnesses and con-
nectors of each circuit except the ECU are found to be
normal in troubleshooting, then it is determined that the
problem is in the ECU. Accordingly, if diagnosis is per-
formed without the problem symptoms occurring, refer to
step 8 to replace the ECU. So always confirm that the
problem symptoms are occurring, or proceed with inspec-
tion while using the symptom simulation method.
S The instructions ”Check wire harness and connector” and
”Check and replace ECU” which appear in the inspection
procedure, are common and applicable to all diagnostic
trouble codes. Follow the procedure outlined below
whenever these instructions appear.
OPEN CIRCUIT:
This could be due to a disconnected wire harness, faulty con-
tact in the connector, and a connector terminal pulled out, etc.
HINT:
S It is rarely the case that a wire is broken in the middle of
it. Most cases occur at the connector. In particular, care-
fully check the connectors of sensors and actuators
S Faulty contact could be due to rusting of the connector
terminals, to foreign materials entering terminals or a de-
formation of connector terminals. Simply disconnecting
and reconnecting the connectors once changes the
condition of the connection and may result in a return to
normal operation. Therefore, in troubleshooting, if no ab-
normality is found in the wire harness and connector
check, but the problem disappears after the check, then
the cause is considered to be in the wire harness or con-
nectors.
SHORT CIRCUIT:
This could be due to a contact between wire harness and the
body ground or to a short circuit occurred inside the switch, etc.
HINT:
When there is a short circuit between the wire harness and body
ground, check thoroughly whether the wire harness is caught
in the body or is clamped properly.

2. CONNECTOR HANDLING
When inserting tester probes into a connector, insert them from
the rear of the connector. When necessary, use mini test leads.
For water resistant connectors which cannot be accessed from
behind, take good care not to deform the connector terminals.
3. CONTINUITY CHECK (OPEN CIRCUIT CHECK)
(a) Disconnect the connectors at both ECU and sensor
sides.
(b) Measure the resistance between the applicable terminals
of the connectors.
Resistance: 1 Ω or less
HINT:
Measure the resistance while lightly shaking the wire harness
vertically and horizontally.
4. RESISTANCE CHECK (SHORT CIRCUIT CHECK)
(a) Disconnect the connectors on both ends.
(b) Measure the resistance between the applicable terminals
of the connectors and body ground. Be sure to carry out
this check on the connectors on both ends.
Resistance: 1 MΩ or higher
HINT:
Measure the resistance while lightly shaking the wire harness
vertically and horizontally.
5. VISUAL CHECK AND CONTACT PRESSURE CHECK
(a) Disconnect the connectors at both ends.
(b) Check for rust or foreign material, etc. in the terminals of
the connectors.
(c) Check crimped portions for looseness or damage and
check that the terminals are secured in lock portion.
HINT:
The terminals should not come out when pulled lightly from the
back.

(d) Prepare a test male terminal and insert it in the female ter-
minal, then pull it out.
NOTICE:
When testing a gold-
-plated female terminal, always use a
gold-
-plated male terminal.
HINT:
When the test terminal is pulled out more easily than others,
there may be poor contact in that section.
6. CHECK OPEN CIRCUIT
For the open circuit in the wire harness in Fig. 1, perform ”(a)
Continuity Check” or ”(b) Voltage Check” to locate the section.
(a) Check the continuity.
(1) Disconnect connectors ”A” and ”C” and measure
the resistance between them.
In the case of Fig. 2,
Between terminal 1 of connector ”A” and terminal 1
of connector ”C” → No continuity (open)
Between terminal 2 of connector ”A” and terminal 2
of connector ”C” → Continuity
Therefore, it is found out that there is an open circuit
between terminal 1 of connector ”A” and terminal 1
of connector ”C”.
(2) Disconnect connector ”B” and measure the resis-
tance between the connectors.
In the case of Fig. 3,
Between terminal 1 of connector ”A” and terminal 1
of connector ”B1” → Continuity
Between terminal 1 of connector ”B2” and terminal
1 of connector ”C” → No continuity (open)
Therefore, it is found out that there is an open circuit
between terminal 1 of connector ”B2” and terminal
1 of connector ”C”.

(b) Check the voltage.
In a circuit in which voltage is applied (to the ECU connec-
tor terminal), an open circuit can be checked for by con-
ducting a voltage check.
As shown in Fig. 4, with each connector still con-
nected, measure the voltage between body ground
and terminal 1 of connector ”A” at the ECU 5V out-
put terminal, terminal 1 of connector ”B”, and termi-
nal 1 of connector ”C”, in that order.
If the results are:
5V: Between Terminal 1 of connector ”A” and Body Ground
5V: Between Terminal 1 of connector ”B” and Body Ground
0V: Between Terminal 1 of connector ”C” and Body Ground
Then it is found out that there is an open circuit in the wire har-
ness between terminal 1 of ”B” and terminal 1 of ”C”.
7. CHECK SHORT CIRCUIT
If the wire harness is ground shorted as in Fig. 5, locate the sec-
tion by conducting a ”continuity check with ground”.
Check the continuity with ground.
(1) Disconnect connectors ”A” and ”C” and measure
the resistance between terminal 1 and 2 of connec-
tor ”A” and body ground.
In the case of Fig. 6
Between terminal 1 of connector ”A” and body
ground → Continuity (short)
Between terminal 2 of connector ”A” and body
ground → No continuity
Therefore, it is found out that there is a short circuit
between terminal 1 of connector ”A” and terminal 1
of connector ”C”.

between terminal 1 of connector ”B2” and terminal
1 of connector ”C”.
8. CHECK AND REPLACE ECU
First check the ECU ground circuit. If it is faulty, repair it. If it is
normal, the ECU could be faulty, so replace the ECU with a nor-
mal functioning one and check that the symptoms appear.
(1) Measure the resistance between the ECU ground
terminal and the body ground.
Resistance: 1 Ω or less
(2) Disconnect the ECU connector, check the ground
terminals on the ECU side and the wire harness
side for bend and check the contact pressure.

1. SRS WARNING LIGHT CHECK
(a) Turn the ignition switch to the ACC or ON position and
check that the SRS warning light lights up.
(b) Check that the SRS warning light goes out after approx.
6 seconds.
HINT:
S When the ignition switch is at ACC or ON and the SRS
warning light remains on or flashes, the airbag sensor as-
sembly has detected a malfunction code.
S If, after approx. 6 seconds have elapsed, the SRS warn-
ing light sometimes lights up or the SRS warning light
lights up even when the ignition switch is OFF, a short in
the SRS warning light circuit can be considered likely.
Proceed to ”SRS warning light circuit malfunction” on
page DI-
-48.
2. DTC CHECK (Using diagnosis check wire)
(a) Present troubles codes:
Output the DTC.
(1) Turn the ignition switch to the ACC or ON position
and wait for approx. 20 seconds.
(2) Using SST, connect terminals Tc and E1 of the
check connector.
SST 09843--18020
NOTICE:
Pay due attention to the terminal connecting position to
avoid a malfunction.
(b) Past troubles codes:
Output the DTC.
(1) Using service wire, connect terminals Tc and E1 of
the check connector.
SST 09843--18020
(2) Turn the ignition switch to the ACC or ON position
and wait for approx. 20 seconds.
NOTICE:
Pay due attention to the terminal connecting position to
avoid a malfunction.

(c) Read the DTC.
Read the 2--digit DTC as indicated by the number of times
the SRS warning light blinks. As an example, the blinking
patterns, normal, 11 and 31 are shown in the illustration.
S Normal code indication
The light will blink 2 times per second.
S Malfunction code indication
The first blinking output indicates the first digit
of a 2--digit DTC. After a 1.5--second pause,
the second blinking output will indicate the
second digit.
If there are 2 or more codes, there will be a 2.5--second pause
between each code. After all the codes have been output, there
will be a 4.0--second pause and they will all be repeated.
HINT:
S In the event of a number of trouble codes, indication will
start from the smallest numbered code.
S If a DTC is not output or a DTC is output without terminal
connection, proceed to the Tc terminal circuit inspection
on page DI--53.
3. DTC CHECK (Using hand-
-held tester)
(a) Hook up the hand--held tester to the DLC3.
(b) Read the DTCs by following the prompts on the tester
screen.
HINT:
Please refer to the hand--held tester operator’s manual for fur-
ther details.
4. DTC CLEARANCE (Not using service wire)
When the ignition switch is turned off, the diagnostic trouble
code is cleared.
HINT:
DTC might not be cleared by turning the ignition switch OFF.
In this case, proceed to the next step.
5. DTC CLEARANCE (Using service wire)
(a) Connect the 2 service wires to terminals Tc and AB of
check connector.
(b) Turn the ignition switch to ACC or ON and wait for approx.
6 seconds.

  • 11. IN0253 WRONG CORRECT IN0252 WRONG CORRECT - - INTRODUCTION REPAIR INSTRUCTIONS IN- -7 (k) Care must be taken when jacking up and supporting the vehicle. Be sure to lift and support the vehicle at the prop- er locations (See page IN--9). S Cancel the parking brake on the level place and shift the transmission in Neutral (or N range). S When jacking up the front wheels of the vehicle, at first place stoppers behind the rear wheels. S When jacking up the rear wheels of the vehicle, at first place stopper before the front wheels. S When either the front or rear wheels only should be jacked up, set rigid racks and place stoppers in front and behind the other wheels on the ground. S After the vehicle is jacked up, be sure to support it on rigid racks. It is extremely dangerous to do any work on a vehicle raised on a jack alone, even for a small job that can be finished quickly. (l) Observe the following precautions to avoid damage to the following parts: (1) Do not open the cover or case of the ECU unless absolutely necessary. (If the IC terminals are touched, the IC may be destroyed by static electric- ity.) (2) To disconnect vacuum hoses, pull off the end, not the middle of the hose. (3) To pull apart electrical connectors, pull on the con- nector itself, not the wires. (4) Be careful not to drop electrical components, such as sensors or relays. If they are dropped on a hard floor, they should be replaced and not reused. (5) When steam cleaning an engine, protect the elec- tronic components, air filter and emission--related components from water. (6) Never use an impact wrench to remove or install temperature switches or temperature sensors. CLICK HERE TO VIEW CHAPTER INDEX Pages From Supplement CONTINUED TO MODEL INDEX RM706E CHAS. & BODY:
  • 12. IN0002 Example IN- -8 - - INTRODUCTION REPAIR INSTRUCTIONS (7) When checking continuity at the wire connector, in- sert the tester probe carefully to prevent terminals from bending. (8) When using a vacuum gauge, never force the hose onto a connector that is too large. Use a step--down adapter for adjustment. Once the hose has been stretched, it may leak air. (m) Installation and removal of vacuum hose: (1) When disconnecting vacuum hoses, use tags to identify where they should be reconnected to. (2) After completing a job, double check that the vacu- um hoses are properly connected. A label under the hood shows the proper layout. (n) Unless otherwise stated, all resistance is measured at an ambient temperature of 20˚C (68˚F). Because the resis- tance may be outside specifications if measured at high temperatures immediately after the vehicle has been run- ning, measurement should be made when the engine has cooled down.

  • 14. IN041- -09 BO4111 Negative Cable IN- -10 - - INTRODUCTION FOR ALL OF VEHICLES FOR ALL OF VEHICLES PRECAUTION 1. FOR VEHICLES EQUIPPED WITH SRS AIRBAG AND SEAT BELT PRETENSIONER (a) The HILUX is equipped with an SRS (Supplemental Re- straint System), such as the driver airbag, front passen- ger airbag assembly and seat belt pretensioners. Failure to carry out service operations in the correct se- quence could cause the supplemental restraint system to unexpectedly deploy during servicing, possibly leading to a serious accident. Further, if a mistake is made in servicing the supplemental restraint system, it is possible the SRS may fail to operate when required. Before servicing (including removal or installation of parts, inspection or replacement), be sure to read the following items carefully, then follow the cor- rect procedure described in this manual. (b) GENERAL NOTICE (1) Malfunction symptoms of the supplemental re- straint system are difficult to confirm, so the diag- nostic trouble codes become the most important source of information when troubleshooting. When troubleshooting the supplemental restraint system, always inspect the diagnostic trouble codes before disconnecting the negative (--) terminal cable from the battery (See page DI--3). (2) Work must be started after 90 seconds from the time the ignition switch is turned to the ”LOCK” posi- tion and the negative (--) terminal cable is discon- nected from the battery. (The supplemental restraint system is equipped with a back--up power source so that if work is started within 90 seconds of disconnecting the neg- ative (--) terminal cable from the battery, the SRS may deploy.) When the negative (--) terminal cable is discon- nected from the battery, memory of the clock and audio systems will be cancelled. So before starting work, make a record of the contents memorized by the each memory system. Then when work is fin- ished, reset the clock and audio systems as before. To avoid erasing the memory of each memory sys- tem, neveruse a back--up powersupply fromanoth- er battery.

  • 15. F01492 Marks - - INTRODUCTION FOR ALL OF VEHICLES IN- -11 (3) Even in cases of a minor collision where the SRS does not deploy, the steering wheel pad, front pas- senger airbag assembly and seat belt pretension- ers should be inspected (See Pub. No. RM585E). (4) Never use SRS parts from another vehicle. When replacing parts, replace them with new parts. (5) Before repairs, remove the airbag sensor if shocks are likely to be attached to the sensor during re- pairs. (6) Never disassemble and repair the airbag sensoras- sembly, steering wheel pad, front passenger airbag assembly or seat belt pretensioner. (7) If the airbag sensor assembly, steering wheel pad, front passenger airbag assembly or seat belt pre- tensioner has been dropped, or if there are cracks, dents or other defects in the case, bracket or con- nector, replace them with new ones. (8) Do not directly expose the airbag sensor assembly, steering wheel pad, front passenger airbag assem- bly or seat belt pretensioner to hot air or flames. (9) Use a volt/ohmmeter with high impedance (10 kΩ/V minimum) for troubleshooting of the electrical cir- cuit. (10) Information labels are attached to the periphery of the SRS components. Follow the instructions on the notices. (11) After work is completed, check the SRS warning light for the supplemental restraint system (See page DI--3). (c) SPIRAL CABLE (in Combination Switch) The steering wheel must be fitted correctly to the steering column with the spiral cable at the neutral position, other- wise cable disconnection and other troubles may result. Refer to SR--26 on Pub. No. RM585E concerning correct steering wheel installation. CLICK HERE TO VIEW CHAPTER INDEX Pages From Supplement CONTINUED TO MODEL INDEX RM706E CHAS. & BODY:

Storing the pad with its metallic surface facing up- ward may lead to a serious accident if the airbag in- flates for same reason. In addition do not store a steering wheel pad on top of another one. (2) Never measure the resistance of the airbag squib. (This may cause the airbag to deploy, which is very dangerous.) (3) Grease should not be applied to the steering wheel pad and the pad should not be cleaned with deter- gents of any kind. (4) Store the steering wheel pad where the ambient temperature remains below 93˚C (200˚F), without high humidity and away from electrical noise. (5) When using electric welding, first disconnect the air- bag connector (yellow color and 2 pins) under the steering column near the combination switch con- nector before starting work. (6) When disposing of a vehicle or the steering wheel pad alone, the airbag should be deployed using an SST before disposal (See page RS--13). Carry out the operation in a safe place away from electrical noise. CLICK HERE TO VIEW CHAPTER INDEX Pages From Supplement TO MODEL INDEX RM706E CONTINUED CHAS. & BODY:

Storing the airbag assembly with the airbag deploy- ment direction facing down could cause a serious accident if the airbag deploys. (2) Never measure the resistance of the airbag squib. (This may cause the airbag to deploy, which is very dangerous.) (3) Grease should not be applied to the front passen- ger airbag assembly and the airbag door should not be cleaned with detergents of any kind. (4) Store the airbag assembly where the ambient tem- perature remains below 93˚C (200˚F), without high humidity and away from electrical noise. (5) When using electric welding, first disconnect the air- bag connector (yellow color and 2 pins) installed on the assembly before starting work. (6) When disposing of a vehicle or the airbag assembly alone, the airbag should be deployed using an SST before disposal (See Pub. No. RM585E on page RS--25).

  • 18. IN- -14 - - INTRODUCTION FOR ALL OF VEHICLES (f) SEAT BELT PRETENSIONER (1) Never measure the resistance of the seat belt pre- tensioner. (This may cause the seat belt pretension- er to activate, which is very dangerous.) (2) Never disassemble the seat belt pretensioner. (3) Never install the seat belt pretensioner in another vehicle. (4) Store the seat belt pretensioner where the ambient temperature remains below 80˚C (176˚F) and away from electrical noise without high humidity. (5) When using electric welding, first disconnect the connector (yellow color and 2 pins) before starting work. (6) When disposing of a vehicle or the seat belt preten- sioner alone, the seat belt pretensioner should be activated before disposal (See Pub. No. RM585E on page BO--137). Perform the operation in a safe place away from electrical noise. (7) The seat belt pretensioner is hot after activation, so let it cool down sufficiently before the disposal. However never apply water to the seat belt preten- sioner. (g) AIRBAG SENSOR ASSEMBLY (1) Never reuse the airbag sensor assembly involved in a collision when the SRS has deployed. (2) The connectors to the airbag sensor assembly should be connected or disconnected with the sen- sor mounted on the floor. If the connectors are con- nected or disconnected while the airbag sensor as- sembly is not mounted to the floor, it could cause undesired deployment of the supplemental re- straint system. (3) Work must be started after 90 seconds from the time the ignition switch is turned to the ”LOCK” posi- tion and the negative (--) terminal cable is discon- nected from the battery, even if only loosing the set bolts of the airbag sensor assembly. (h) WIRE HARNESS AND CONNECTOR The SRS wire harness is integrated with the instrument panel wire harness assembly. All the connectors in the system are a standard yellow color. If the SRS wire har- ness becomes disconnected or the connector becomes broken due to an accident, etc., repair or replace it.

IN04S- -13 IN- -16 - - INTRODUCTION HOW TO TROUBLESHOOT ECU CONTROLLED SYSTEMS HOW TO TROUBLESHOOT ECU CONTROLLED SYSTEMS GENERAL INFORMATION A large number of ECU controlled systems are used in the HILUX. In general, the ECU controlled system is considered to be a very intricate system requiring a high level of technical knowledge and expert skill to troubleshoot. However, the fact is that if you proceed to inspect the circuits one by one, troubleshooting of these systems is not complex. If you have adequate understanding of the system and a basic knowledge of electricity, accurate diagnosis and necessary repair can be performed to locate and fix the problem. This manual is designed through emphasis of the above standpoint to help service technicians perform accurate and effective troubleshooting, and is compiled for the following major ECU controlled systems: The troubleshooting procedure and how to make use of it are described on the following pages. System Page 1. Supplemental Restraint System DI- -1 FOR USING HAND- -HELD TESTER S Before using the tester, the tester’s operator manual should be read thoroughly. S If the tester cannot communicate with ECU controlled systems when you have connected the cable of the tester to DLC3, turned the ignition switch ON and operated the tester, there is a problem on the vehicle side or tester side. (1) If communication is normalwhen the tester is connected to another vehicle, inspect the diagnosis data link line (Busline) or ECU power circuit of the vehicle. (2) If communication is still not possible when the tester is connected to another vehicle, the problem is probably in the tester itself, so perform the Self Test procedures outline in the Tester Operator’s Manual.

CUSTOMER PROBLEM ANALYSIS In troubleshooting, the problem symptoms must be confirmed accurately and all preconceptions must be cleared away in order to give an accurate judgment. To ascertain just what the problem symptoms are, it is extremely important to ask the customer about the problem and the conditions at the time it occurred. Important Point in the Problem Analysis: The following 5 items are important points in the problem analysis. Past problems which are thought to be unrelated and the repairhistory, etc. may also help in some cases, so as much information as possible should be gathered and its relationship with the problem symptoms should be correctly ascertained for reference in troubleshooting. A customer problem analysis table is provided in Diagnostics section for each system for your use. CLICK HERE TO VIEW CHAPTER INDEX Pages From Supplement TO MODEL INDEX RM706E CONTINUED CHAS. & BODY:

SYMPTOM CONFIRMATION AND DIAGNOSTIC TROUBLE CODE CHECK The diagnostic system in the HILUX fulfills various functions. The first function is the Diagnostic Trouble Code Check in which a malfunction in the signal circuits to the ECU is stored in code in the ECU memory at the time of occurrence, to be output by the technician during troubleshooting. Another function is the Input Signal Check which checks if the signals from various switches are sent to the ECU correctly. By using these check functions, the problem areas can be narrowed down quickly and troubleshooting can be performed effectively. Diagnostic functions are incorporated in the following systems in the HILUX. System Diagnostic Trouble Code Check Input Signal Check (Sensor Check) Diagnostic Test Mode (Active Test) Supplemental Restraint System f In diagnostic trouble code check, it is very important to determine whether the problem indicated by the diag- nostic trouble code is still occurring or occurred in the past but returned to normal at present. In addition, it must be checked in the problem symptom check whether the malfunction indicated by the diagnostic trouble code is directly related to the problem symptom or not. For this reason, the diagnostic trouble codes should be checked before and after the symptom confirmation to determine the current conditions, as shown in the table below. If this is not done, it may, depending on the case, result in unnecessary troubleshooting for normally operating systems, thus making it more difficult to locate the problem, or in repairs not pertinent to the problem. Therefore, always follow the procedure in correct order and perform the diagnostic trouble code check.

SYMPTOM SIMULATION The most difficult case in troubleshooting is when there are no problem symptoms occurring. In such cases, a thorough customer problem analysis must be carried out, then simulate the same or similar conditions and environment in which the problem occurred in the customer’s vehicle. No matter how much experience a technician has, or how skilled he may be, if he proceeds to troubleshoot without confirming the problem symptoms he will tend to overlook something important in the repair operation and make a wrong guess somewhere, which will only lead to a standstill. For example, for a problem which only occurs when the en- gine is cold, or for a problem which occurs due to vibration caused by the road during driving, etc., the prob- lem can never be determined so long as the symptoms are confirmed with the engine hot condition or the vehicle at a standstill. Since vibration, heat or water penetration (moisture) is likely cause for problem which is difficult to reproduce, the symptom simulation tests introduced here are effective measures in that the ex- ternal causes are applied to the vehicle in a stopped condition. Important Points in the Symptom Simulation Test: In the symptom simulation test, the problem symptoms should of course be confirmed, but the problem area or parts must also be found out. To do this, narrow down the possible problem circuits according to the symp- toms before starting this test and connect a tester beforehand. After that, carry out the symptom simulation test, judging whether the circuit being tested is defective or normal and also confirming the problem symp- toms at the same time. Refer to the problem symptoms table for each system to narrow down the possible causes of the symptom.

When the malfunction seems to occur on a rainy day or in a high- -humidity condition. Heat the component that is the likely cause of the malfunction with a hair dryer or similar object. Check to see if the malfunction occurs. Sprinkle water onto the vehicle and check to see if the malfunc- tion occurs. Turn on all electrical loads including the heater blower, head lights, rear window defogger, etc. and check to see if the mal- function occurs. ON HINT: If a vehicle is subject to water leakage, the leaked water may contaminate the ECU. When testing a vehicle with a water leak- age problem, special caution must be taken. M a l f u n c- tion Do not heat to more than 60 ˚C (140 ˚F). (Temperature is limited not to damage the components.) Do not apply heat directly to parts in the ECU. (1) (2) Never sprinkle water directly into the engine compart- ment, but indirectly change the temperature and hu- midity by applying water spray onto the radiator front surface. Never apply water directly onto the electronic compo- nents.

CONNECTOR CONNECTION AND TERMINAL IN- SPECTION S For troubleshooting, diagnostic trouble code charts or problem symptom table are provided for each circuit with detailed inspection procedures on the following pages. S When all the component parts, wire harnesses and con- nectors of each circuit except the ECU are found to be normal in troubleshooting, then it is determined that the problem is in the ECU. Accordingly, if diagnosis is per- formed without the problem symptoms occurring, refer to step 8 to replace the ECU. So always confirm that the problem symptoms are occurring, or proceed with inspec- tion while using the symptom simulation method. S The instructions ”Check wire harness and connector” and ”Check and replace ECU” which appear in the inspection procedure, are common and applicable to all diagnostic trouble codes. Follow the procedure outlined below whenever these instructions appear. OPEN CIRCUIT: This could be due to a disconnected wire harness, faulty con- tact in the connector, and a connector terminal pulled out, etc. HINT: S It is rarely the case that a wire is broken in the middle of it. Most cases occur at the connector. In particular, care- fully check the connectors of sensors and actuators S Faulty contact could be due to rusting of the connector terminals, to foreign materials entering terminals or a de- formation of connector terminals. Simply disconnecting and reconnecting the connectors once changes the condition of the connection and may result in a return to normal operation. Therefore, in troubleshooting, if no ab- normality is found in the wire harness and connector check, but the problem disappears after the check, then the cause is considered to be in the wire harness or con- nectors. SHORT CIRCUIT: This could be due to a contact between wire harness and the body ground or to a short circuit occurred inside the switch, etc. HINT: When there is a short circuit between the wire harness and body ground, check thoroughly whether the wire harness is caught in the body or is clamped properly.

CHECK OPEN CIRCUIT For the open circuit in the wire harness in Fig. 1, perform ”(a) Continuity Check” or ”(b) Voltage Check” to locate the section. (a) Check the continuity. (1) Disconnect connectors ”A” and ”C” and measure the resistance between them. In the case of Fig. 2, Between terminal 1 of connector ”A” and terminal 1 of connector ”C” → No continuity (open) Between terminal 2 of connector ”A” and terminal 2 of connector ”C” → Continuity Therefore, it is found out that there is an open circuit between terminal 1 of connector ”A” and terminal 1 of connector ”C”. (2) Disconnect connector ”B” and measure the resis- tance between the connectors. In the case of Fig. 3, Between terminal 1 of connector ”A” and terminal 1 of connector ”B1” → Continuity Between terminal 1 of connector ”B2” and terminal 1 of connector ”C” → No continuity (open) Therefore, it is found out that there is an open circuit between terminal 1 of connector ”B2” and terminal 1 of connector ”C”.

If the results are: 5V: Between Terminal 1 of connector ”A” and Body Ground 5V: Between Terminal 1 of connector ”B” and Body Ground 0V: Between Terminal 1 of connector ”C” and Body Ground Then it is found out that there is an open circuit in the wire har- ness between terminal 1 of ”B” and terminal 1 of ”C”. 7. CHECK SHORT CIRCUIT If the wire harness is ground shorted as in Fig. 5, locate the sec- tion by conducting a ”continuity check with ground”. Check the continuity with ground. (1) Disconnect connectors ”A” and ”C” and measure the resistance between terminal 1 and 2 of connec- tor ”A” and body ground. In the case of Fig. 6 Between terminal 1 of connector ”A” and body ground → Continuity (short) Between terminal 2 of connector ”A” and body ground → No continuity Therefore, it is found out that there is a short circuit between terminal 1 of connector ”A” and terminal 1 of connector ”C”.

CHECK AND REPLACE ECU First check the ECU ground circuit. If it is faulty, repair it. If it is normal, the ECU could be faulty, so replace the ECU with a nor- mal functioning one and check that the symptoms appear. (1) Measure the resistance between the ECU ground terminal and the body ground. Resistance: 1 Ω or less (2) Disconnect the ECU connector, check the ground terminals on the ECU side and the wire harness side for bend and check the contact pressure.

SRS WARNING LIGHT CHECK (a) Turn the ignition switch to the ACC or ON position and check that the SRS warning light lights up. (b) Check that the SRS warning light goes out after approx. 6 seconds. HINT: S When the ignition switch is at ACC or ON and the SRS warning light remains on or flashes, the airbag sensor as- sembly has detected a malfunction code. S If, after approx. 6 seconds have elapsed, the SRS warn- ing light sometimes lights up or the SRS warning light lights up even when the ignition switch is OFF, a short in the SRS warning light circuit can be considered likely. Proceed to ”SRS warning light circuit malfunction” on page DI- -48. 2. DTC CHECK (Using diagnosis check wire) (a) Present troubles codes: Output the DTC. (1) Turn the ignition switch to the ACC or ON position and wait for approx. 20 seconds. (2) Using SST, connect terminals Tc and E1 of the check connector. SST 09843--18020 NOTICE: Pay due attention to the terminal connecting position to avoid a malfunction. (b) Past troubles codes: Output the DTC. (1) Using service wire, connect terminals Tc and E1 of the check connector. SST 09843--18020 (2) Turn the ignition switch to the ACC or ON position and wait for approx. 20 seconds.

Read the 2--digit DTC as indicated by the number of times the SRS warning light blinks. As an example, the blinking patterns, normal, 11 and 31 are shown in the illustration. S Normal code indication The light will blink 2 times per second. S Malfunction code indication The first blinking output indicates the first digit of a 2--digit DTC. After a 1.5--second pause, the second blinking output will indicate the second digit. If there are 2 or more codes, there will be a 2.5--second pause between each code. After all the codes have been output, there will be a 4.0--second pause and they will all be repeated. HINT: S In the event of a number of trouble codes, indication will start from the smallest numbered code. S If a DTC is not output or a DTC is output without terminal connection, proceed to the Tc terminal circuit inspection on page DI--53. 3. DTC CHECK (Using hand- -held tester) (a) Hook up the hand--held tester to the DLC3. (b) Read the DTCs by following the prompts on the tester screen. HINT: Please refer to the hand--held tester operator’s manual for fur- ther details. 4. DTC CLEARANCE (Not using service wire) When the ignition switch is turned off, the diagnostic trouble code is cleared. HINT: DTC might not be cleared by turning the ignition switch OFF. In this case, proceed to the next step. 5. DTC CLEARANCE (Using service wire) (a) Connect the 2 service wires to terminals Tc and AB of check connector.
