1. FOR VEHICLES EQUIPPED WITH SRS AIRBAG AND SEAT BELT PRETENSIONER
HINT:
The HIGHLANDER is equipped with a Supplemental Restraint System (SRS) and seat belt pretensioner.
Failure to carry out the service operations in the correct sequence could cause the SRS to unexpectedly
deploy during servicing and lead to serious injury.
Furthermore, if a mistake is made when servicing the SRS, it is possible that the SRS may fail to operate
properly. Before servicing (including removal or installation of parts, inspection or replacement), be sure to
read the following section carefully.
(a) GENERAL NOTICE
(1) Malfunction symptoms of the SRS are difficult to confirm so the Diagnostic Trouble Codes (DTCs)
become the most important source of information when troubleshooting. When troubleshooting
the SRS, always check the DTCs before disconnecting the battery (see page 05-1215 ).
(2) To avoid serious injury, servicing the SRS must be started at least 90 seconds after:
S The ignition switch is turned to the LOCK position.
S The negative (-) terminal cable is disconnected from the battery.
(The SRS is equipped with a back-up power source. If work is started within 90 seconds of dis-
connecting the negative (-) terminal cable from the battery, the SRS may deploy.)
Disconnecting the negative (-) terminal cable will erase the memory of all vehicle systems. Initial-
ize the systems after disconnecting/reconnecting the cable.
CAUTION:
Never use a back-up power source (battery or other) in an attempt to avoid erasing system memory.
The back-up power source inadvertently may inadvertently power the SRS and cause it to deploy.
(3) In minor collisions where the SRS does not deploy, the horn button assembly, instrument panel
passenger airbag assembly, front seat airbag assembly, curtain shield airbag assembly and seat
belt pretensioner should be inspected before further use of the vehicle (see pages 60-19 ,
60-31 , 60-40 , 60-46 , and 61-8 ).
(4) Never use SRS parts from another vehicle. When replacing parts, use new parts.
(5) Before repairs, remove the airbag sensor if impacts are likely to be applied to the sensor during
repairs.
(6) Never disassemble and repair the airbag sensor assembly, horn button assembly, instrument
panel passenger airbag assembly, front seat airbag assembly, curtain shield airbag assembly
or seat belt pretensioner.
(7) Replace the center airbag sensor assembly, side airbag sensor assembly, horn button assembly
or the instrument panel passenger airbag assembly, front seat airbag assembly or curtain shield
airbag assembly if: 1) damage has occurred from being dropped, or 2) cracks, dents or other
defects in the case, bracket or connector are present.
(8) Do not directly expose the airbag sensor assembly, the horn button assembly, the instrument
panel passenger airbag assembly, front seat airbag assembly, the curtain shield airbag assem-
bly or the seat belt pretensioner to hot air or flames.
(9) Use a voltmeter/ohmmeter with high impedance (10 kΩ/V minimum) for troubleshooting electri-
cal circuits.
(10) Information labels are attached to the SRS components. Follow the instructions on the labels.
(11) After work on the SRS is completed, check the SRS warning light (see page 05-1207 ).

(b) SPIRAL CABLE (in Combination Switch)
(1) The steering wheel must be fitted correctly to the
steering column with the spiral cable at the neutral
position, otherwise cable disconnection and other
problems may occur. Refer to page 60-26 for in-
formation about correct installation of the steering
wheel.
(c) HORN BUTTON ASSEMBLY (with Airbag)
(1) When removing the horn button assembly or handling a new horn button, it should be placed with
the pad surface facing up. See illustration below.
Placing the horn button with the pad surface facing down may lead to a serious accident if the
airbag accidently inflates. Also, do not place anything on top of the horn button.
(2) Never measure the resistance of the airbag squib. This may cause the airbag to inflate, which
could cause serious injury.
(3) Grease or detergents of any kind should not be applied to the steering wheel pad.
(4) Store the horn button assembly in an area where the ambient temperature is below 93°C
(200°F), the humidity is not high and electrical noise is not nearby.
(5) When using electric welding anywhere on the vehicle, disconnect the airbag ECU connectors
(4 pins). These connectors contain shorting springs. This feature reduces the possibility of the
airbag or seat belt pretensioner deploying due to currents entering the squib wiring.
(6) When disposing of the vehicle or the horn button assembly by itself, the airbag should be inflated
using an SST before disposal (see page 60-19 ). Perform the operation in a safe place away from
electrical noise.

(d) INSTRUMENT PANEL PASSENGER AIRBAG ASSY
(1) Always place a removed or new instrument panel passenger airbag assembly with the airbag
inflation direction facing up.
Placing the airbag assembly with the airbag inflation direction facing down could cause a serious
accident if the airbag inflates.
(2) Never measure the resistance of the airbag squib. This may cause the airbag to inflate, which
could cause serious injury.
(3) Grease or detergents of any kinds should not be applied to the instrument panel passenger air-
bag assembly.
(4) Store the airbag assembly in an area where the ambient temperature is below 93°C (200°F),
the humidity is not high and electrical noise is not nearby.
(5) When using electric welding anywhere on the vehicle, disconnect the airbag ECU connectors
(4 pins). These connectors contain shorting springs. This feature reduces the possibility of the
airbag deploying due to currents entering the squib wiring.
(6) When disposing of a vehicle or the airbag assembly unit by itself, the airbag should be deployed
using SST before disposal (see page 60-31 ).
Activate in a safe place away from electrical noise.
(e) CURTAIN SHIELD AIRBAG ASSEMBLY
(1) Always place the removed or new curtain shield airbag assembly in a clear plastic bag, and keep
it in a safe place.
NOTICE:
Plastic bag is not re-useable.
CAUTION:
Never disassemble the curtain shield airbag assembly.
(2) Never measure the resistance of the airbag squib. This may cause the airbag to inflate, which
is very dangerous.
(3) Grease should not be attached to the curtain shield airbag assembly, and the surface should not
be cleared with detergents of any kind.

(f) FRONT SEAT AIRBAG ASSEMBLY
(1) Always place a removed or new front seat airbag assembly with the airbag inflation direction fac-
ing up. Placing the airbag assembly with the airbag inflation direction facing downward could
cause a serious accident if the airbag deploys.
(2) Never measure the resistance of the airbag squib. This may cause the airbag to inflate, which
is very dangerous.
(3) Grease should not be applied to the front seat airbag assembly, and the airbag door should not
be cleaned with detergents of any kind.
(4) Store the airbag assembly in an area where the ambient temperature is below 93°C (200°F),
the humidity is not high and electrical noise is not nearby.
(5) When using electric welding anywhere on the vehicle, disconnect the airbag ECU connectors
(2 pins). These connectors contain shorting springs. This feature reduces the possibility of the
airbag deploying due to currents entering the squib wiring.
(6) When disposing of a vehicle or the airbag assembly unit by itself, the airbag should be deployed
using SST before disposal (see page 60-46 ).
Activate in a safe place away from electrical noise.

(g) SEAT BELT PRETENSIONER
(1) Never measure the resistance of the seat belt pretensioner. This may cause the seat belt preten-
sioner to activate, which is very dangerous.
(2) Never disassemble the seat belt pretensioner.
(3) Never install the seat belt pretensioner on another vehicle.
(4) Store the seat belt pretensioner in area where the ambient temperature is below 80°C (176°F),
the humidity is not high and electrical noise is not nearby.
(5) When using electric welding anywhere on the vehicle, disconnect the airbag ECU connectors
(2 pins). These connectors contain shorting springs. This feature reduces the possibility of the
airbag deploying due to currents entering the squib wiring.
(6) When disposing of a vehicle or the seat belt pretensioner unit by itself, the seat belt pretensioner
should be activated before disposal (see page 61-8 ). Activate in a safe place away from electri-
cal noise.
(7) The seat belt pretensioner is hot after being activated, so allow some time for it to cool down suffi-
ciently before disposal. Never apply water to cool down the seat belt pretensioner.
(8) Oil or water should not be put on the front seat outer belt, and the front seat outer belt should
not be cleaned with detergents of any kind.
(h) AIRBAG SENSOR ASSEMBLY
(1) Never reuse an airbag sensor assembly that has been involved in a collision where the SRS has
deployed.
(2) The connectors to the airbag sensor assembly should be connected or disconnected with the
sensor mounted on the floor. If the connectors are connected or disconnected while the airbag
sensor assembly is not mounted to the floor, it could cause accidental deployment of the SRS.
(3) Work must be started at least 90 seconds after the ignition switch is turned to the LOCK position
and the negative (-) terminal cable is disconnected from the battery, even if only loosening the
set bolts of the airbag sensor assembly.

(i) WIRE HARNESS AND CONNECTOR
(1) The SRS wire harness is integrated with the instrument panel wire harness assembly. All the con-
nectors in the system are a standard yellow color. If the SRS wire harness becomes discon-
nected or the connector becomes broken, repair or replace it.
2. ELECTRONIC CONTROL
(a) REMOVAL AND INSTALLATION OF BATTERY TERMI-
NAL
(1) Before performing electronic work, disconnect the
battery negative (-) terminal cable beforehand to
prevent component and wire damage caused by
accidental short circuits.
(2) When disconnecting and installing the terminal
cable, turn the ignition switch and lighting switch
OFF and loosen the terminal nut completely. Per-
form these operations without twisting or prying the
terminal. Remove the battery cable from battery
post.
(3) Clock settings, radio settings, DTCs and other data
are erased when the battery cable is removed. Be-
fore removing the battery cable, record any neces-
sary data.
(4) When disconnecting the battery’s negative (-) ter-
minal cable, re-initialize the following systems after
the completion of the operation.
(b) HANDLING OF ELECTRONIC 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 rendered inoperative by
static electricity.
(2) To disconnect electronic connectors, pull the con-
nector itself, not the wires.
(3) Be careful not to drop electronic components, such
as sensors or relays. If they are dropped on a hard
floor, they should be replaced.
(4) When cleaning the engine with steam, protect the
electronic components, air filter and emission-re-
lated components from water.
(5) Never use an impact wrench to remove or install
temperature switches or temperature sensors.
(6) When checking the continuity at the wire connector,
insert the tester probe carefully to prevent terminals
from bending.
