C. Repair Driver Airbag Wiring and.or Replace Clockspring
IMPORTANT:This section is only for vehicles with a "Driver Squib Term Shorted to Ground" diagnostic trouble code.
1. Place the steering wheel in the straight ahead position.
2. With the ignition switch in the OFF position, disconnect the negative battery cable.
NOTE:
To enhance customer satisfaction, remember to record all radio settings before disconnecting the battery and to reset all electronic memory (clock, radio settings, etc.) when you have completed the service procedure.
3. Remove the upper and lower steering column shrouds.
4. Inspect the clockspring wiring pigtail routed along the steering column for cuts or chafing (Figure 6).
^ If NO cuts or chafing of the clockspring pigtail is found, continue with Step 5.
^ If cuts or chafing of the clockspring pigtail is found, but no wire strands have been damaged, repair the clockspring wires by taping the damaged area with high quality electrical tape and tie strap as shown in Figure 6.
^ If cuts or chafing of the clockspring pigtail is found and internal wire strands have been damaged, replace the clockspring assembly as follows:
a. Remove the four (4) airbag module retaining nuts from the back side of the steering wheel, disconnect the airbag module electrical connector and then remove the airbag module from the steering wheel and set it aside (inflator side down/face up for safety).
b. Disconnect the speed control switch connector (if equipped).
c. Disconnect the horn connector.
d. Remove the steering wheel retaining nut and then using a steering wheel puller (Special Tool C-3428B), remove the steering wheel.
e. Disconnect the clockspring wiring connector near the top of the fuse block and unclip the wiring pigtail from the steering column.
f. Disconnect the clockspring wiring connector from the back of the clockspring.
g. Unclip the clockspring assembly locating fingers from the steering column and then remove and discard the clockspring.
h. Snap the new clockspring onto the steering column.
i. Route the clockspring pigtail down the steering column such that the section of the I/P wiring harness that connects to the ignition switch is between the pigtail and the steering column. Secure the clockspring pigtail to the I/P wiring harness with a tie strap (P/N 05016944AA) (Figure 6).
j. Connect the clockspring pigtail to the I/P wiring harness connector. Secure the clockspring pigtail to the I/P wiring harness near the fuse/relay/kneeblocker bracket with a tie strap (P/N 05016944AA) (Figure 6).
k. Install the steering wheel. Torque the steering wheel retaining nut to 45 ft-lbs (61 Nm).
l. Connect the horn connector.
m. Connect the speed control switch connector (if equipped).
n. Connect the airbag module electrical connector and install the airbag module onto the steering wheel. Torque the airbag module retaining nuts to 90 in-lbs (10 Nm).
5. Install the upper and lower steering column shrouds.
6. Inspect the I/P wiring harness where it is routed past the brake pedal support to verify that the harness tie strap/clip is secured into the hole (Figure 7).
^ If the tie strap/clip is on the harness but not in the hole, inspect the wiring harness for damage. Any chafed or cut wires should be repaired per the Wiring Repair Procedure.
^ If the tie strap/clip is missing or damaged, install a new tie strap/clip (P/N 05016944AA) and insert the clip into the hole.
7. Install another mastic patch on the edge of the brake pedal support bracket to prevent damage to the I/P wiring harness as it routes up past the fuse block (Figure 7).
8. Remove the relay access cover.
9. Inspect the I/P wiring harness and verify that the harness tie strap/clip has been inserted into the tab off of the fuse/relay/kneeblocker bracket (Figure 8).
^ If the clip is on the harness but not in the hole, inspect the wiring harness for damage. Any chafed or cut wires should be repaired per the Wiring Repair Procedure.
^ If the tie strap/clip is missing or damaged, install a new tie strap/clip (P/N 0516944AA) and insert the clip into the hole.
10. Install another mastic patch to the outboard end of the steel tube that routes the transmission shifter cable and the steering column support bracket closest to the I/P wiring harness (Figure 8).
11. Install the relay access cover.
12. Install the lower steering column cover (Figure 1).
13. Connect the liftgate release switch electrical connector (Figure 1).
14. Connect the liftgate release switch electrical connector (Figure 1).
15. Tighten the lower instruments panel cover screws securely.
16. Remove the two (2) screws that attach the lower console to the instrument panel support brackets (Figure 9).
17. Slide the cupholder out.
18. Remove the two (2) upper console attaching screws behind the cupholder (Figure 9).
19. Slide the console rearward and up to remove.
20. Inspect the I/P wiring harness where it connects to the Airbag Electronic Control Module (AECM) (Figure 10). Any chafed or cut wires should be repaired per the Wiring Repair Procedure.
21. Install another mastic patch over the rear corner and left edge of the Body Control Module (BCM) (Figure 10).
22. Install the console assembly.
23. Install the upper console attaching screws behind the cupholder. Tighten the screws securely. Close the cupholder.
24. Install the two (2) lower console attaching screws (Figure 9). Tighten the screws securely.
25. ^ If any other airbag system diagnostic trouble codes were detected and must still be repaired, continue with the appropriate section of the Service Procedure to correct that issue.
^ If no other diagnostic trouble codes require correction, continue with Step 26.
26. Turn the ignition switch to the ON position and exit the vehicle.
27. Connect the negative battery terminal.
28. From outside the vehicle, turn the ignition switch to the OFF position for about 10 seconds and then back to the ON position.
29. Observe the airbag warning light in the instrument cluster. It should illuminate for 6-8 seconds and then go out.
NOTE:
If the airbag warning light fails to light or lights and stays on, there is a system malfunction. Refer to the proper Body Diagnostic Procedures manual to diagnose and repair the problem.
