Removal






REMOVAL

WARNING: To avoid serious or fatal injury on vehicles equipped with airbags, disable the supplemental restraint system before attempting any steering wheel, steering column, airbag, seat belt tensioner, impact sensor, or instrument panel component diagnosis or service. Disconnect and isolate the battery negative (ground) cable, then wait two minutes for the system capacitor to discharge before performing further diagnosis or service. This is the only sure way to disable the supplemental restraint system. Failure to take the proper precautions could result in accidental airbag deployment.

CAUTION: A service replacement Steering Control Module (SCM) is shipped with the clockspring pre-centered and with a molded plastic locking pin installed. This locking pin should not be removed until the SCM has been installed on the steering column. If the locking pin is removed before the SCM is installed on a steering column, the clockspring centering procedure must be performed.

NOTE: Before starting this procedure, be certain to turn the steering wheel until the front wheels are in the straight-ahead position and that the entire steering system is locked or inhibited from rotation.





1. Place the front wheels in the straight ahead position.

2. Disconnect and isolate the battery negative cable.

3. Remove the driver airbag from the steering wheel.

4. Disconnect the steering wheel wire harness connectors from the upper clockspring rotor connector receptacles.

CAUTION: Be certain that the screws that secure the steering wheel puller to the steering wheel are fully engaged in the steering wheel armature without passing through the steering wheel and damaging the clockspring.

5. Remove the steering wheel from the steering column.

6. Remove the shrouds from the steering column.

7. Remove the right (wiper ) multi-function switch (3) from the SCM (4).

8. Remove the left (lighting) multi-function switch (1) from the SCM.

9. Remove the hazard switch (2) from the SCM.





10. Disconnect the two instrument panel wire harness connectors (3 and 4) from the two connector receptacles located below the steering column (5) on the back of the SCM case (2).





11. Remove the two screws (1) that secure the SCM (3) to the steering column housing (2).

12. Remove the SCM from the steering column housing. The SCM/clockspring cannot be repaired. It must be replaced if ineffective or damaged, or if the driver airbag has been deployed.

13. If the removed SCM is to be reused, be certain to secure the clockspring rotor to the SCM case to maintain clockspring centering until it is reinstalled on the steering column. If clockspring centering is not maintained, the clockspring must be centered again before it is reinstalled.

14. Remove the turn signal cancel cam from the clockspring rotor of the SCM.
