Service Procedure
A. Inspect Steering Column Control Module Data Label
1. Turn the steering wheel to the 6 o'clock position (Figure 1).
2. Unsnap the knee bolster at the top of the bolster and allow it to hinge downward (Figure 2).
3. Remove the upper and lower plastic steering column shrouds.
4. Inspect the first four digits of the Julian data code (disregard the fifth digit) on the label located on the bottom of the Steering Column Control Module (Figure 3) for the following:
> If the Julian date code on the bar code data label is 0409, 0419, or 0429 continue with Section B. Inspect Steering Column Control Module Wiring Orientation.
> If the Julian date code on the bar code data label is not 0409, 0419, or 0429 the Steering Column Control Module does not require further inspection or replacement. Continue with Step 5 of this procedure.
5. Install the steering column cover shrouds.
6. Install the knee bolster.
7. Return the vehicle to the customer.
B. Inspect Steering Column Control Module Wiring Orientation
WARNING:
To avoid serious or fatal injury on vehicles equipped with airbags, disable the Supplemental Restraint System (SRS) before attempting Steering Column Control Module replacement. Disconnect and isolate the battery negative (ground) cable, then wait two minutes for the system capacitor to discharge before proceeding. This is the only sure way to disable the SRS. Failure to take the proper precautions could result in accidental airbag deployment.
1. Disconnect and isolate the negative battery cable, then wait two minutes before proceeding.
2. Place the steering wheel in the straight ahead position.
NOTE:
The front wheels must also be in the straight ahead position.
3. Separate the driver airbag module from the steering wheel but do not disconnect the driver airbag module squib wires.
CAUTION:
Do not allow the driver airbag module to hang by the squib wires.
NOTE:
Some models use three clips to hold the driver airbag module to the steering wheel (Figure 4).
4. Remove the black electrical tape that holds the two sets of squib wires together (Figure 5).
5. Inspect the driver airbag module squib wiring orientation going into the Steering Column Control Module (Figure 6):
> If the pair of red and blue wires going into the Steering Column Control Module enter on the left side and the pair of yellow and brown wires enter on the right side, the Steering Column Control Module does not require repair. Continue with Step 6 of this procedure.
> If the pair of red and blue wires going into the Steering Column Control Module enter on the right side and the pair of yellow and brown wires enter on the left side, the Steering Column Control Module is defective and must be replaced. Continue with Section C. Replace Steering Column Control Module.
6. Install the driver airbag module onto the steering wheel.
7. Install the steering column cover shrouds.
8. Install the knee bolster.
9. Connect the negative battery cable.
10. Return the vehicle to the customer.
C. Replace Steering Column Control Module
CAUTION:
The clockspring in the Steering Column Control Module is shipped with the clockspring pre-centered and with a molded plastic locking pin installed. This locking pin must not be removed until the steering wheel has been installed on the steering column (Step 20).
1. Disconnect the driver airbag module wires and place the module aside.
2. Disconnect the white steering wheel wiring connector.
3. Remove the steering wheel retaining bolt.
4. Remove the steering wheel from the steering shaft.
5. Move the steering column to the fully lowered position.
6. Remove the three screws that secure the Steering Column Control Module to the steering column bracket.
7. Pull the Steering Column Control Module away from the steering column far enough to access and disconnect the three instrument panel wire harness connectors from the receptacles on the back of the Steering Column Control Module case.
8. Remove the Steering Column Control Module from the steering column.
9. Transfer the right multi-function switch from the old Steering Column Control Module to the new Steering Column Control Module (Figure 7).
10. Transfer the left multi-function switch from the old Steering Column Control Module to the new Steering Column Control Module (Figure 8).
11. Transfer the multi-function switch jumper harness from the old Steering Column Control Module onto the new Steering Column Control Module (Figure 8).
CAUTION:
Make sure that the jumper wire connectors are locked in place by gently pulling on them.
12. Carefully slide the Steering Column Control Module down over the steering column upper shaft far enough to reconnect the three instrument panel wire harness connectors to the receptacles on the back of the Steering Column Control Module case.
13. Position the Steering Column Control Module onto the steering column bracket.
14. Install and tighten the three screws that secure the Steering Column Control Module to the steering column bracket to 27 in. lbs. (3 N.m) in the following sequence:
> Lower right screw
> Upper left screw
> Upper right screw
CAUTION:
Use of an improper sequence when tightening the Steering Column Control Module mounting screws may result in an audible ticking noise as the steering wheel is rotated.
15. Install the upper and lower shrouds onto the steering column.
16 Install the knee bolster.
17. Move the steering column back to the fully raised position and move the tilt release lever to the locked position.
18. Install the steering wheel onto the steering column.
19. Install the steering wheel retaining bolt and tighten bolt to 45 ft. lbs. (61 N.m).
20. Remove the plastic locking pin that secures the clockspring rotor to the Steering Column Control Module case.
21. Connect the white steering wheel wiring connector.
22. Connect the squib connectors to the driver airbag module.
23. Install the driver airbag module to the steering wheel.
24. Perform the Supplemental Restraints Verification Test below:
a. Connect the scan tool to the 16-way data link connector located on the driver's side lower edge of the instrument panel.
b. Turn the ignition switch to the "ON" position and exit the vehicle with the scan tool.
c. Check and make certain that nobody is in the vehicle, then reconnect the negative battery cable.
d. Using the scan tool, read and record active and historical Diagnostic Trouble Codes (DTC's).
e. Use the scan tool to erase the stored DTC's.
f. Turn the ignition to the "OFF" position for about 15 seconds, and then back to the "ON" position. Observe the airbag indicator lamp in the instrument cluster. It should light for six to eight seconds and then go out. This indicates that the SRS is functioning normally and that the repairs are complete.
g. Remove the scan tool from the vehicle.
h. Return the vehicle to the customer.
