Acceptable Coolant Level Switch
Application - This device is suitable for use as a Coolant Level switch. Its complementary outputs satisfy the
unique functional requirements of the ECM interface. The switch is mounted with the sensor probe extending
into the radiator or overflow tank at the minimum coolant level. The radiator or overflow tank requires a 1/4
NPT boss to mount the switch. Apply thread sealant before installing the switch, omit sealant on first full
thread. The switch is available in limited quantities through Cummins distributors.
Hardware - The switch is manufactured by Robert Shaw. The switch is an electronic switch which operates on
the capacitance sensing principle. The probe of the component detects a change in electrical capacitance
when the liquid displaces the air immediately surrounding the probe. The change is converted within the
component into the required logic. The sensor requires a +5V power supply for operation, which is available
from the ECM. The switch mates to a Packard Metri-Pack 150 series connector. A cable seal and secondary
lock are available and required.

Use of LEDs is generally not recommended due to the leakage current. LEDs may be dimly lit instead of
completely off.
Water-in-Fuel (WIF) Lamp
The water-in-fuel lamp indicates there is water in the fuel. When the lamp is illuminated the vehicle
driver/operator should release the water from the fuel filter.
As an option the WIF lamp may be eliminated and the maintenance lamp can be used to provide the water-in-
fuel indication. This can be done by routing a wire from the ECM OEM connector WIF lamp signal in parallel
with the wire from the ECM OEM connector maintenance lamp signal. The WIF lamp should be installed on the
operator switch panel.
Maintenance Lamp

Switched Sink Driver Output Pinout Specifications
Applications
The Switched Sink Driver Output Pinout type sinks an OEM-supplied load, which are typically dashboard
lamps. The Pinout is connected to one side of the OEM load. A voltage source, typically Vbatt+, is connected
to the other side of the OEM load.
Operation
The Switched Sink Driver Output Pinout can exist in one of two states: Sink (low impedance) or Off (high
impedance). These states are dictated by a microprocessor-controlled FET switch.
• Sink State - Pinout Voltage can be measured at the pinout with respect to ECM ground. When the FET
switch is opened, Pinout Current is present through the pinout by way of the FET switch. Load Resistance
can be measured between the pinout and the OEM voltage source. The OEM load is on or energized.
• Off State - When the FET switch is closed, some leakage Pinout current is still present by way of the 47K
resistor. The OEM load is off or de-energized.

Section III: Relays
Low Idle Shutdown Relay
The Low Idle Shutdown relay removes power from high-current machine devices when the engine is shut down
by the Low Idle Shutdown feature. This feature shuts down the engine in the presence of excessive engine
idling with no operator interaction, in the effort to increase fuel economy. When shutdown occurs, battery drain
may occur because the engine is stopped but the keyswitch is on. To reduce battery drain, the Low Idle
Shutdown relay disconnects power from high-current devices such as the HVAC blower. The relay is usually
installed on the fuse panel.
The Low Idle Shutdown relay has two states, powered and shutdown. When the relay is in the powered
state, the engine is keyed off, running, or in any condition other than a shutdown condition initiated by the Low
Idle Shutdown feature. The relay is de-energized, high-current devices receive electrical power through
normally closed contacts of the relay. When the relay is in the shutdown state, the engine has been shut
down by the Low Idle Shutdown feature. The relay is energized, the high-current devices are unpowered. The
relay remains in this state until the keyswitch is turned off or the engine is cranked for restart.

Intake Air Heater Relay (Grid Heater)
Applications
The Air Heater relay controls operating power to an OEM-supplied grid heater. The grid heater heats the intake
manifold immediately before and after the engine is started, which improves cold engine starting and reduces
white smoke. The grid heater is automatically activated by the Intake Air heater feature when the engine is
cold. The Intake Air Heater relay is normally installed in the engine compartment.
The Intake Air Heater relay has two states, heat or off. Intake manifold heating will occur immediately before
and after engine start depending on a combination of intake manifold temperature and coolant temperature.
When intake manifold heating is required, the relay assumes heat. Operating power is applied to the grid
heater through normally open contacts of the relay. When intake manifold heating is no longer required, the
relay assumes off. Operating power is removed from the grid heater.

control signal follows the key switch state. The VP44 Power Relay along with a 5 foot extension harness is
shipped with the engine. The OEM is responsible for choosing an appropriate location for the relay and
mounting it in the equipment. The relay can be mounted in any loacation where exposure to road splash is
absent and vibration is minimized. It should be mounted with the tab up (wires down) in a vertical orientation.

Section IV: Switches
Switch Conventions
Introduction
This document has standardized the manner in which switches are defined in order to promote maximum
comprehension of the switch requirements. There are two features of every switch, configuration and
characteristics. Each feature may be described for a switch using words or symbols. This document uses both
methods.
Switch Configuration
A switch configuration is the number of poles and the number of throws. Poles are the number of electrically
independent switch contacts that are simultaneously switched. Throws are the number of switch positions that
result in a switch contact.
• Descriptions - When defining switch configuration by words, the number of poles are indicated by prefix (S
for single, D for double, 3,5,etc.) followed by the letter P. The number of throws is indicated by the same
prefixes, followed by the letter T. For example, a single-pole, double-throw switch is written as SPDT.
• Symbols - When defining switch configuration using a picture, the number of poles are indicated by the
number of switch wipers connected by a dashed line. The number of throws are typically indicated by the
number of terminals (numbered open circles) to which a wiper connects.
Switch Diagram Legend
Switch Characteristics
A switch characteristic is the contact and action at each switch position. Contact is whether the switch position
makes or breaks an electrical connection at that position. Action is whether the switch position is momentary or
latched.
• Descriptions - When defining switch characteristics by words, contact is indicated by an on or an off
which is supplied for each switch position. Momentary action is indicated by parenthesis around (on) or
(off); latched action is indicated by an absence of parenthesis
• Symbols - When defining switch characteristics by pictures, contact is indicated if a terminal (numbered
open circle) is present at that switch position. Momentary action is indicated by a filled triangle at that
switch position; latched action is indicated by a filled circle at that switch position.

Alternate Droop Switch
Application
The Alternate Droop switch selects different droop characteristics for the High Idle Governor feature or the All
Speed Governor (ASG) feature or both. This is desirable when the machine is transitioning to a different mode
of operation, for example from loading to hauling. The transition may be performed by any dedicated switch
contacts, including a relay or a manual operator switch. Installation depends on the type of switch that is used..

Alternate Low Idle Switch
Application
The Alternate Low Idle switch selects a different low idle engine speed. A higher low idle engine speed is
useful for warming up the engine, or when an application operates the engine on low idle governor. The
alternate low idle engine speed may be selected by any dedicated switch contacts, including a relay or a
manual operator switch. Installation depends on the type of switch that is used.
Operation
The Alternate low Idle switch has two positions, base low idle or alternate low idle. The switch operates in
the Normal or Transition mode depending on an optional customer selection.
• Normal Mode - When the switch is in the base low idle position, the engine's low idle speed is defined by
the Low Idle Governor feature. When the switch is in the alternate low idle position, engine low idle speed
is instead defined by the Switchable Low Idle feature.
• Transition Mode - This mode requires a switch transition from base low idle to alternate low idle
subsequent to key-on to select the alternate low idle. Until this transition has occurred, or when the switch
is in the Base Low Idle position, engine low idle speed is defined by the Low Idle Governor feature. If the
transition has occurred and the switch is in the alternate low idle position, engine low idle speed is instead
defined by the Switchable Low Idle feature.

Alternate Torque Switch
Applications
The Alternate Torque switch toggles between the normal 100% curve and up to two alternate torque curves. A
different torque curve results in an engine with different HP ratings. Different horsepower ratings are desirable
when the same engine is used for dual modes of operation, for example hauling vs. loading. A torque curve
may be selected by any dedicated switch contacts, including a relay or a manual operator switch. Installation
depends on the type of switch that is used.
Operation without Boost Power
The following operational description applies when the Automatic Boost Power feature is not enabled. The
Alternate Torque switch has two or three switch positions (see switch diagram). When the switch is in the Low
position, a lower calibratible torque curve is used. Engine torque is limited to the lower curve. The ECM may
be calibrated for either a Normal or Failsafe configuration of the switch.

AXG On/Off Switch
Application
The AXG On/Off switch selects operation of the Auxiliary Speed Governor (AXG), AXG is an auxiliary fueling
governor that varies engine torque in an attempt to control either shaft speed or an application-specific
pressure, depending upon the engine configuration.
The AXG On/Off switch has two positions, on or off. When the switch is in the off position, the engine fueling
is not controlled by the AXG. When the switch is in the on position and there are no AXG faults, engine fueling
is controlled by the AXG, permitting shaft speed control or pressure control from a commanded throttle input.

Air Conditioner Pressure Switch
Applications
The Air Conditioner Pressure switch detects air condition refrigerant pressure relative to two pressure
thresholds defined by the switch. It generates a control signal for the Electronic Fan Clutch feature which in
turn operates an air conditioning condenser fan. This switch is inserted into the high-pressure side of the air
conditioner refrigerant system. A hysteresis of 2-4 PSI is recommended between the two pressure thresholds
to prevent an excessive number of fan clutch state transitions.
The Air Condition Pressure switch has two positions, pressure high or pressure not high, and two thresholds,
upper and lower. On rising refrigerant pressure, the switch will transition to the Pressure High position when
pressure exceed the upper threshold. In this position, On/Off fan will operate at its characteristic RPM, a
Variable-Speed fan will operate at selectable rpm. On falling refrigerant pressure, the switch will transition to
the pressure not high position when pressure falls below the lower threshold. In this switch position, the fan
does not operate due to refrigerant pressure. However, the fan may still run in response to some other need
such as high coolant temperature.

Pressure Switches: Brake Switch
Description
This normally closed sing pole, single throw (SPST) plunger design limit switch is rated for one million switch
cycles. It has an actuation force of 4.17 N [0.937 lbf] (15 ounces) and the total plunger movement is 4.928 mm
[0.1938 in]. The recommended switch actuation is 3.175 mm [0.1249 in] to avoid undesirable bottoming out.
An elastomeric sealing boot keeps harsh abrasive from damaging the plunger body and guide. Gold contacts
make the switch reliable for low voltage and current switching.
Application
The signal from the brake pressure is used to disable cruise control and ISC operations. It is mounted directly,
or with a T-fitting, into the low pressure control side of the truck's pneumatic brake system. When the brake
pedal is actuated or the trailer brake is applied, the pneumatic pressure rises from 0 psig to 90 psig. An open
circuit to the control module, whether by this switch or a wiring circuit failure, will disable the cruise control
function. This switch is qualified for under-the-dashboard mounting only. A molded rubber boot is
recommended for use with the mating connector.

Switches and Switch Assemblies: Rotary Clutch Switch Assembly
Description
The Clutch Switch Assembly is comprised of a rotary switch, lever and rod assembly and a switch bracket. The
rotary switch is a normally closed single pole, single throw switch that is designed to exceed one million switch
cycles. Gold contacts make it reliable for low voltage and current switching. The shaft is 7.87 millimeters
[0.309 in] in diameter. At the open position, actuation torque is 1.34 N-m [0.988 ft-lbf] (190 inch-ounces). Total
mechanical travel is 40 degrees of maximum rotation with 35 degrees of maximum pretravel and 3 degrees of
differential travel. The ruggedness of this switch allows it to be used in high vibration environments.
Application
The device can be mounted either in the cab or under the cab. The rod is cut or bent to fit the top or front side
of the clutch arm so that the clutch rest position has the switch in the closed-circuit mode. As the clutch pedal
is depressed, the linkage arm will move and the spring preload in the switch will cause the rod to follow and
open the switch circuit. When mounted under the cab, a shield should be added to prevent direct road splash
on the rotary shaft area.

Switches and Switch Assemblies: Optional Clutch Brake Switch
Description
This normally closed single pole, single throw (SPST) plunger design limit switch is rated for one million switch
cycles. It has an actuation force of 4.17 N [0.937 lbf[ (15 ounces) and the total plunger movement is 4.928 mm
[0/1938 in]. The recommended switch actuation is 3.176 mm [0.1249 in] to avoid undesirable bottoming out.
An elastomeric sealing boot keeps harsh abrasives from damaging the plunger body and guide. Gold contacts
make the switch reliable for low voltage and current switching.
Application
The limit switch may be closed as an optional clutch switch instead of the rotary clutch switch assembly. It is
mounted on the bell housing of the transmission and is operated by an actuating bracket attached to the bell
crank. The slim packaging of this harsh environment plunger switch allows it to be easily mounted for limited
switch application. Two mounting holes 5.08 mm [0.199 in] in diameter accommodate number 10 capscrews
for bracket compatibility. The actuators that impinge on the plunger should be adjusted to the specified range
of the switch.

SECTION V: SENSORS
Vehicle Speed Sensor (Variable Reluctance Magnetic Pickup)
Application - This sensor is mounted through the transmission case and senses passing teeth from a 16-tooth
or optional 11-tooth gear. Each revolution of the gear produces 16 or 11 cycles of quasi-sinusoidal voltage.
The sensor responds down to 1 mph which is 31 rpm of the 16-tooth speedometer gear shown in the
accompanying illustration. At the time of installation, the sensor is to be hand turned until it touches the target,
then backed off one-half turn and the jam nut tightened. The sensor is polarity sensitive and a sharp positive-
to-negative transition is accomplished by using the white lead wire as the positive reference and the black wire
as the negative reference. It can also be used as a dual output engine speed sensor, mounted through the ring
gear housing to sense ring gear teeth.
Hardware - This sensor is a single pole piece, dual output variable reluctance magnetic pickup in which each
output is physically isolated from the other. The output swings positive when the target approaches, passes
through zero when the target and pole piece are coincident, and then swings negative when the target leaves.
Voltage amplitude is a function of gap, target size and angular velocity.

ANALOG SENSORS
OEM Pressure Sensor
Application -The OEM Pressure sensor may be used to detect the pressure of any desired liquid or gas. OEM
pressure can be used to switch any device on or off, to initiate an engine shutdown, or to control a fan. OEM
Pressure can be governed to a reference pressure in order to drive air- or hydraulically-powered equipment.
Any or all applications can be met at once. Installation varies according to application.
Operation - The OEM Pressure sensor converts detected pressure into a DC voltage. This voltage is detected
by the ECM and converted into OEM pressure using a calculation that performs a linear interpolation between
two breakpoints. OEM pressure may be used by any or all of the following features:
• Auxiliary Governor - This feature converts throttle input into a reference OEM pressure. Then using a
feedback loop, engine torque is varied as required to maintain this OEM pressure. Depending on the
application, OEM pressure can be maintained at a pre-selected value, or continuously variable OEM
pressure control is possible.
• Electronic Fan Clutch - If the fan type is Variable-Speed, OEM pressure is applied to a calibration table to
generate a characteristic PWM frequency. The fan will operate at the minimum fan speed corresponding to
the characteristic PWM frequency. If the fan type is On/Off, the fan will turn on or off when OEM pressure
transitions through a pressure threshold.
• Switched Outputs - OEM pressure is one of several trigger parameters for three options: Relay A, Relay
B, and Engine Shutdown. Each option has one or more associated pressure thresholds. Depending on
OEM pressure value relative to these thresholds, the OEM pressure trigger parameter is either ACTIVE or
INACTIVE for each option. When the desired combination of trigger parameters is ACTIVE for the Relay A
option, that relay energizes or de-energizes. When the desired combination of trigger parameters is
ACTIVE for the Relay B option, that relay energizes or de-energizes. When the desired combination of
trigger parameters is ACTIVE for the Engine Shutdown option, an engine shutdown is initiated.

OEM Temperature Sensor Specifications
Application – The OEM temperature sensor may be used to detect the temperature of any desired liquid or
gas. The detected temperature can be used to switch any device on or off, to initiate an engine shutdown, or to
control a fan. Any or all applications can be met at once. Installation varies according to application.
Operation – The OEM temperature sensor converts detected temperature into a resistance. This resistance is
detected by ECM and converted into OEM temperature using a table with 20 breakpoints. OEM temperature
may be used by either or both of the following features.
a. Electronic Fan Clutch – If the fan type is variable-speed, OEM temperature is applied to a calibration
table to generate a characteristic PWM frequency. The fan will operate at the minimum fan speed
corresponding to the characteristic PWM frequency. If the fan type is on/off, the fan will turn on or off
when OEM temperature transitions through a temperature threshold.
b. Switched Outputs – OEM temperature is one of several trigger parameters for three options: Relay A,
Relay B, and Engine Shutdown. Each option has one or more associated temperature thresholds.
Depending on OEM temperature relative to these thresholds, the OEM temperature trigger parameter
is either ACTIVE or INACTIVE for each option. When the desired combination of trigger parameters is
ACTIVE for the Relay A option, that relay energizes or deenergizes. When the desired combination of
trigger parameters is ACTIVE for Relay B option, that relay energizes or deenergizes. When the
desired combination of trigger parameters is ACTIVE for the engine Shutdown option and Engine
Shutdown is initiated.
