Airbag Control Module
REMOVALWARNING:
- ON VEHICLES EQUIPPED WITH AIRBAGS, DISABLE THE SUPPLEMENTAL RESTRAINT SYSTEM BEFORE ATTEMPTING ANY STEERING WHEEL, STEERING COLUMN, DRIVER AIRBAG, PASSENGER AIRBAG, SEAT BELT TENSIONER, SIDE CURTAIN AIRBAG, 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 AIRBAGS. 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. FAILURE TO OBSERVE THIS WARNING COULD RESULT IN ACCIDENTAL, INCOMPLETE, OR IMPROPER AIRBAG DEPLOYMENT AND POSSIBLE OCCUPANT INJURIES.
1. Disconnect and isolate the battery negative cable. Wait two minutes for the system capacitor to discharge before further service.
2. From the right side of the floor panel transmission tunnel, remove the screw that secures the floor duct adapter to the bottom of the heater-air conditioner housing.
3. Remove the floor duct adapter from the bottom of the heater-air conditioner housing.
4. Pull the carpet on the right and left sides of the floor panel transmission tunnel rearward far enough to access the Airbag Control Module (ACM).
Fig. 5 Airbag Control Module:
5. Remove the two screws that secure the ACM to the right side of the mounting bracket that is welded onto the floor panel transmission tunnel.
6. Remove the two screws that secure the ACM to the left side of the mounting bracket that is welded onto the floor panel transmission tunnel.
7. Lift the ACM upward from the mounting bracket far enough to disengage the locator pins on the ACM housing from the locator holes in the mounting bracket, then pull the ACM out from under the instrument panel far enough to access the wire harness connector.
8. Disconnect the instrument panel wire harness connector for the ACM from the ACM connector receptacle. To disconnect the instrument panel wire harness connector for the ACM:
a. Slide the red Connector Position Assurance (CPA) lock on the top of the connector toward the right side of the vehicle.
b. Depress the latch tab on the upper surface of the connector, and pull the connector straight away from the ACM connector receptacle.
9. Remove the ACM from beneath the instrument panel.

FAILURE TO OBSERVE THIS WARNING COULD RESULT IN ACCIDENTAL, INCOMPLETE, OR IMPROPER AIRBAG DEPLOYMENT AND POSSIBLE OCCUPANT INJURIES.
1. Position the Airbag Control Module (ACM) beneath the instrument panel.
2. 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 fully engaged.
3. Carefully position the ACM to the mounting bracket that is welded onto the floor panel transmission tunnel. When the ACM is correctly positioned, the locator pins on the ACM housing will be engaged in the locator holes in the mounting bracket, and the arrow on the ACM label will be pointed forward in the vehicle.
4. Install and tighten the two screws that secure the ACM to the right side of the mounting bracket that is welded onto the floor panel transmission tunnel. Tighten the screws to 12 Nm (105 in. lbs.).
5. Install and tighten the two screws that secure the ACM to the left side of the mounting bracket that is welded onto the floor panel transmission tunnel. Tighten the screws to 12 Nm (105 in. lbs.).
6. Restore the carpet on the right and left sides of the floor panel transmission tunnel to its proper position beneath the instrument panel.
7. From the right side of the floor panel transmission tunnel, position the floor duct adapter onto the bottom of the heater-air conditioner housing.
8. Install and tighten the screw that secures the floor duct adapter to the bottom of the heater-air conditioner housing. Tighten the screw to 2 Nm (17 in. lbs.).
9. 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. (Refer to RESTRAINTS - STANDARD PROCEDURE - VERIFICATION TEST).
