Modify Cruise Control Module
Important: The cruise control module must be modified as described in the following procedure
before installing it on a RHD domestic vehicle.
- Depress the release tab on the adjuster and slide the adjuster off the cruise
control module rod.
- Remove and discard the accelerator pedal bracket.
- Install the adjuster on the cruise module rod. The adjuster and rod are keyed
to ensure proper orientation.
- Confirm that the adjuster is locked to the rod by pulling the adjuster
rearward (the adjuster should slide forward but not rearward when properly installed).
Install Cruise Control Module
- Locate the cruise control harness taped in the I/P harness, under the dash,
near the center console air duct. (The cruise control harness has a black 6-pin connector.)
Notice: Refer to Fastener Notice in the Preface section.
- Install the cruise control module on the steering column support bracket and
tighten the nuts.
Tighten
Tighten the cruise control module-to-steering column bracket to 6 N·m (53 lb in).
- Connect the cruise control rod bracket to the accelerator pedal. Snap
the locating tab into the hole in the accelerator pedal.
- Connect the cruise control module harness connector. Push in the connector
until a click is heard and pull back to confirm a positive engagement.
Adjust Cruise Control Module Rod
Refer to
Cruise Control Module Rod Adjustment
.
Remove Steering Wheel and Inflator Module
LHD shown; RHD similar.
- Disable the SIR system. Refer to
Disabling the SIR System
in SIR.
- Turn the steering wheel to the 3 o'clock position.
- Remove the inflator module by inserting a short flat blade screwdriver
into the triangle shaped hole in the rear steering wheel shroud.
- Turn the screwdriver to release the spring fastener, while lifting up
on the corner of the inflator module closest to that fastener.
- Repeat step 4 for the next fastener.
- Turn the steering wheel to 9 o'clock position.
- Repeat step 4 until all the spring fasteners are released.
- Disconnect the inflator module harness and the horn lead.
- Remove the inflator module.
- Disconnect the harness from the steering wheel.
Notice: If roll connector is not properly oriented to steering column assembly, it will
be damaged.
- Remove the steering wheel attachment nut and discard.
- Install J 1859-A
by fitting J 42578
into the steering wheel puller
holes.
- Install the puller bridge over the puller legs and finger, tighten the
steering wheel puller nuts on the legs.
- Insert the center bolt through the bridge and align with the steering
column shaft.
- Tighten the center bolt until the steering wheel is disengaged.
- Remove the steering wheel while feeding wiring through the wheel opening.
Important: If yellow tab is not available, use tape to prevent coil from rotating. If coil
is rotated, refer to
Inflatable Restraint Steering Wheel Module Coil Replacement
in SIR.
- Insert yellow tab or use a piece of tape to prevent coil assembly from rotating.
Install New Steering Wheel and Inflator Module
- Remove the yellow tab or tape from the SIR coil assembly.
- Route wiring through the steering wheel and install the steering wheel
onto the steering shaft noting orientation notch that locates steering wheel in the
correct position.
Important: A new steering wheel attachment nut must be used.
- Install the new steering wheel attachment nut.
Tighten
Tighten the steering wheel attachment nut to 40 N·m (30 lb ft).
- Connect the cruise control switch connector and attach the harness to the wheel.
Push in the connectors until a click is heard and pull back to confirm a positive
engagement.
- Connect the inflator module wiring harness and install the harness integral
connector lock device.
- Install the inflator module into the steering wheel. Be sure to seat all
attachment points.
- Enable the SIR system. Refer to
Enabling the SIR System
in SIR.
Reprogram PCM EEPROM Option To Enable Cruise Bit
Important: In order to set the CRUISE CONTROL option to YES, the entire PCM has to be reprogrammed.
The latest software and calibrations can be selected for downloading if this is desired.
Change the CRUISE CONTROL option to YES by reprogramming the powertrain control
module (PCM) using the Service Stall System (SSS). Refer to the Service Stall System
(SSS) User Guide for reprogramming procedures.
System Performance Test
Complete the following procedures to confirm the installed cruise control system
functions properly:
- Drive the vehicle at a speed of at least 40 km/h (25 mph)
then enable the cruise control by turning the cruise ON/OFF switch to On.
Important: The PCM must see at least one brake switch transition in the ignition cycle
to allow cruise operation.
- Cycle the brake pedal twice.
- Engage the cruise control by depressing the SET/COAST switch for a minimum
period of 60 milliseconds (ms).
- Release foot from accelerator pedal. The vehicle should maintain cruise
set speed.
- Disengage the cruise control by pressing the brake pedal. The vehicle
should start to decelerate.
- Depress the RES/ACCEL switch for a minimum period of 60 ms. The
vehicle should accelerate to the cruise set speed before the brake pedal was depressed.
- Press the RES/ACCEL switch for 60 ms to 700 ms. The vehicle
should increase speed by 2 km/h (1 mph).
- Disable the cruise control by turning the cruise ON/OFF switch to Off.
The vehicle should slow down until the accelerator pedal is depressed.
- If all of the above is operating correctly, then the cruise system is
functioning correctly. Conclude the test by verifying no "active" DTCs are present
in the PCM.
