Airbag Control Module

On some models, particularly van conversions, the driver side front seat riser may require removal in order to access the Airbag Control Module (ACM) and the ACM cover for service.

WARNING:
- ON VEHICLES EQUIPPED WITH AIR-BAGS, DISABLE THE SUPPLEMENTAL RESTRAINT SYSTEM BEFORE ATTEMPTING ANY STEERING WHEEL, STEERING COLUMN, DRIVER AIRBAG, PASSENGER AIRBAG, SEAT BELT TENSIONER, 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 AND POSSIBLE PERSONAL INJURY.
- THE AIRBAG CONTROL MODULE CONTAINS THE IMPACT SENSOR, WHICH ENABLES THE SYSTEM TO DEPLOY THE SUPPLEMENTAL RESTRAINTS. NEVER STRIKE OR DROP THE AIR-BAG 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. FAILURE TO OBSERVE THIS WARNING COULD RESULT IN ACCIDENTAL, INCOMPLETE, OR IMPROPER SUPPLEMENTAL RESTRAINT DEPLOYMENT AND POSSIBLE OCCUPANT INJURIES.

REMOVAL
1. Disconnect and isolate the battery negative cable. Wait two minutes for the system capacitor to discharge before further service.
2. Remove the ACM cover from the front floor panel.

Airbag Control Module Remove/Install:

3. Reach under the front of the driver side front seat riser to access and disconnect the instrument panel wire harness connector for the ACM from the ACM connector receptacle located on the forward facing side of the module. To disconnect the instrument panel wire harness connector from the ACM:
a. Slide the red Connector Position Assurance (CPA) lock on the top of the connector toward the side of the connector.
b. Depress the connector latch tab and pull the connector straight away from the ACM connector receptacle.
4. Remove the three screws that secure the ACM to the bracket that is welded onto the floor panel under the driver side front seat.
5. Lift the ACM upward far enough to disengage the locating pins on the bottom of the ACM mounting flanges from the locating holes in the mounting bracket.
6. Remove the ACM from under the driver side front seat.

INSTALLATION
1. Carefully position the ACM to the mounting bracket that is welded onto the floor panel under the driver side front seat. When the ACM is correctly positioned, the locating pins on the ACM mounting flanges will be engaged in the locator holes in the mounting bracket, and the orientation arrow on the ACM label will be pointed forward in the vehicle.
2. Install and tighten the three screws that secure the ACM to the mounting bracket that is welded onto the floor panel under the driver side front seat. Tighten the screws to 12 N.m (105 in. lbs.).
3. Reach under the front of the driver side front seat to access and reconnect the instrument panel wire harness connector for the ACM to the ACM connector receptacle. Be certain that the connector latch and the red Connector Position Assurance (CPA) lock are each fully engaged.
4. Install a new ACM cover over the ACM and onto the front floor panel. The ACM cover MUST be replaced with a new cover following service removal.
5. Do not reconnect the battery negative cable at this time. The supplemental restraint system verification test procedure should be performed following service of any supplemental restraint system component.
