Air Bag Control Module: Service and Repair

WARNING:
- THE AIR BAG CONTROL MODULE CONTAINS THE IMPACT SENSOR, WHICH ENABLES THE SYSTEM TO DEPLOY THE AIR BAG. 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. FAILURE TO OBSERVE THIS WARNING COULD RESULT IN ACCIDENTAL, INCOMPLETE, OR IMPROPER AIRBAG DEPLOYMENT AND POSSIBLE OCCUPANT INJURIES.

REMOVAL
1. Disconnect and isolate the battery negative cable. If either of the airbags has not been deployed, wait two minutes for the system capacitor to discharge before further service.
2. Remove the left front bucket seat assembly from the passenger compartment of the vehicle.

Airbag Control Module Remove/Install:

3. Remove the three screws that secure the Airbag Control Module (ACM) protective cover to the floor panel and the ACM mounting bracket.
4. Lift the ACM protective cover away from the ACM far enough to access and disengage the instrument panel floor wire harness retainer from the slotted mounting hole near the rear of the cover.
5. Reach under the front of the driver side front seat to access and disconnect the instrument panel floor wire harness connector from the Airbag Control Module (ACM). To disconnect the instrument panel floor wire harness connector from the ACM:
a. Squeeze the two connector latch tabs between the thumb and forefinger.
b. Pull the connector straight away from the ACM connector receptacle.
6. Remove the three nuts that secure the ACM mounting bracket to the mount that is welded onto the floor panel.
7. Remove the ACM from the mount on the floor panel.

INSTALLATION
1. Carefully position the ACM to the mount that is welded onto the floor panel. When the ACM is correctly positioned the arrow on the ACM label will be pointed forward in the vehicle.
2. Install and tighten the three nuts that secure the ACM to the mount. Tighten the nuts to 7.3 N.m (65 in. lbs.).
3. Reconnect the instrument panel floor wire harness connector to the ACM connector receptacle. Be certain that the connector latches are fully engaged.
4. Position the protective cover over the ACM.
5. Engage the instrument panel floor wire harness retainer in the slotted mounting hole near the rear of the ACM protective cover.
6. Install and tighten the three screws that secure the ACM protective cover to the floor panel and the ACM mounting bracket. Tighten the screws to 4 N.m (35 in. lbs.).
7. Install the left front bucket seat assembly into the passenger compartment of the vehicle.
