Air Bag Control Module: Service and Repair

WARNING:
^ THE AIRBAG CONTROL MODULE CONTAINS THE IMPACT SENSOR, WHICH ENABLES THE SYSTEM TO DEPLOY THE AIRBAG. BEFORE ATTEMPTING TO DIAGNOSE OR SERVICE ANY AIRBAG SYSTEM OR RELATED STEERING WHEEL, STEERING COLUMN, OR INSTRUMENT PANEL COMPONENTS YOU MUST FIRST DISCONNECT AND ISOLATE THE BATTERY NEGATIVE (GROUND) CABLE. THEN WAIT TWO MINUTES FOR THE SYSTEM CAPACITOR TO DISCHARGE BEFORE FURTHER SYSTEM SERVICE. THIS IS THE ONLY SURE WAY TO DISABLE THE AIRBAG SYSTEM. FAILURE TO DO THIS COULD RESULT IN ACCIDENTAL AIRBAG DEPLOYMENT AND POSSIBLE PERSONAL INJURY.
^ NEVER STRIKE OR KICK THE AIRBAG CONTROL MODULE, AS IT CAN DAMAGE THE IMPACT SENSOR OR AFFECT ITS CALIBRATION. IF AN AIRBAG CONTROL MODULE IS ACCIDENTALLY DROPPED DURING SERVICE, THE MODULE MUST BE SCRAPPED AND REPLACED WITH A NEW UNIT. ALWAYS REINSTALL THE AIRBAG CONTROL MODULE PROTECTIVE COVER.

1. Disconnect and isolate the battery negative cable. If the airbag has not been deployed, wait two minutes for the system capacitor to discharge before further service.
2. Remove the left front bucket seat assembly.




3. Remove the three screws that secure the Air-bag Control Module (ACM) protective cover to the left front floor pan and the ACM mounting bracket.
4. Pull the ACM protective cover away from the ACM far enough to access and release the ACM wire harness retainer from the slotted hole near the rear of the cover.
5. Remove the ACM protective cover from the vehicle.
6. Unplug the ACM wire harness connector. To unplug the connector, squeeze the two connector latch tabs between the thumb and forefinger, while pulling the connector out from the ACM.
7. Remove the three nuts that secure the ACM mounting bracket to the floor pan mounting bracket.
8. Remove the ACM from the vehicle.
9. When installing the ACM, position the unit with the arrow on the ACM housing pointing forward.
10. Attach the ACM to the floor pan ACM mounting bracket with the three mounting nuts. Tighten the mounting nuts to 7.3 N.m (65 in. lbs.).
11. Plug in the wire harness connector to the ACM. Be certain that the connector latches are fully engaged.
12. Position the ACM protective cover over the ACM. Be certain that the wire harness retainer is correctly reinstalled in the slotted hole of the ACM protective cover. Tighten the mounting screws to 4 N.m (35 in. lbs.).
13. Reverse the remaining removal procedures to complete the installation.
14. Do not connect the battery negative cable at this time. See Testing and Inspection/Procedures for the proper procedures.
