Follow Figure 2 throughout this procedure.

1. Crimp the terminal for the X1 connector to a wire which

will be inserted into pin location 17 of the X1 connector.

Connect the other end of the wire to the Relay coil.

2. Connect a second wire to ignition power, by either splicing

the wire into the wire located in pin 7 of the X1 connector or

make a connection to the ignition switch, in either case be

sure the connection is protected by a 5 AMP fuse. Connect

the other end of the wire to the Relay coil.

3. Connect a third wire to the engine ECM mechanical retarder

connection - see the vehicle manufacturer's manual as

needed for location. Connect the other end of the wire to

the Relay (typically the common/wiper connection).

4. Connect a fourth wire to the other side of the NO (normally

open) connection on the relay and connect the other end of

the wire to ignition power, following the wiring diagram.

5. Install all other wire harness connectors, checking that

each connector snaps into the locked position.

OPERATIONAL TEST AND

RECONFIGURATION

Use a diagnostic tool such as the Bendix

program, Nexiq Pro Link (using the Eaton cartridge), or blink

code switch (see Figure 3 below and Service Data Sheet

SD-13-4767) to reconﬁ gure the ECU to a 4 sensor, 4 modulator,

with retarder relay (if applicable) conﬁ guration.

Before returning the vehicle to service, use the diagnostic

tool to check the installation. Also, check for any diagnostic

trouble codes present and troubleshoot and/or make repairs

as necessary.

GENERAL MAINTENANCE PRECAUTIONS

WARNING! PLEASE READ AND FOLLOW THESE

INSTRUCTIONS TO AVOID PERSONAL INJURY OR

DEATH:

When working on or around a vehicle, the following general

precautions should be observed at all times.

1. Park the vehicle on a level surface, apply the parking

brakes, and always block the wheels. Always wear

safety glasses.

2. Stop the engine and remove ignition key when working

under or around the vehicle. When working in the

engine compartment, the engine should be shut

off and the ignition key should be removed. Where

circumstances require that the engine be in operation,

EXTREME CAUTION should be used to prevent

personal injury resulting from contact with moving,

rotating, leaking, heated or electrically charged

components.

3. Do not attempt to install, remove, disassemble or

assemble a component until you have read and

thoroughly understand the recommended procedures.

Use only the proper tools and observe all precautions

pertaining to use of those tools.

4. If the work is being performed on the vehicle's air brake

system, or any auxiliary pressurized air systems, make

certain to drain the air pressure from all reservoirs

before beginning ANY work on the vehicle. If the

vehicle is equipped with an AD-IS

a dryer reservoir module, be sure to drain the purge

reservoir.

5. Following the vehicle manufacturer's recommended

procedures, deactivate the electrical system in a

manner that safely removes all electrical power from

the vehicle.

6. Never exceed manufacturer 's recommended

pressures.

7. Never connect or disconnect a hose or line containing

pressure; it may whip. Never remove a component or

plug unless you are certain all system pressure has

been depleted.

8. Use only genuine Bendix

components and kits. Replacement hardware, tubing,

hose, ﬁ ttings, etc. must be of equivalent size, type

and strength as original equipment and be designed

speciﬁ cally for such applications and systems.

9. Components with stripped threads or damaged parts

should be replaced rather than repaired. Do not

attempt repairs requiring machining or welding unless

speciﬁ cally stated and approved by the vehicle and

component manufacturer.

10. Prior to returning the vehicle to service, make certain

all components and systems are restored to their

proper operating condition.

11. For vehicles with Antilock Traction Control (ATC),

the ATC function must be disabled (ATC indicator

lamp should be ON) prior to performing any vehicle

maintenance where one or more wheels on a drive axle

are lifted off the ground and moving.
