Airbag Control Module

REMOVAL

WARNING:
- ON VEHICLES EQUIPPED WITH AIRBAGS, DISABLE THE SUPPLEMENTAL RESTRAINT SYSTEM BEFORE ATTEMPTING ANY STEERING WHEEL, STEERING COLUMN, DRIVER AIRBAG, PASSENGER AIRBAG, SEAT BELT TENSIONER, FRONT IMPACT SENSORS, 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 FRONT SUPPLEMENTAL RESTRAINTS. NEVER STRIKE OR DROP 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 FRONT SUPPLEMENTAL RESTRAINT 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. Remove the center console from the top of the floor panel transmission tunnel.

Fig.7 ACM Cover Remove/Install:




3. From the left side of the floor panel transmission tunnel, remove the Airbag Control Module (ACM) cover from the ACM. The cover flange is secured to the silencer pad on the floor panel transmission tunnel with double-faced tape.
4. Remove the ground screw that secures the ground lug on the left rear corner of the ACM housing to the ACM bracket on the floor panel transmission tunnel.

Fig.8 Airbag Control Module Remove/Install:




5. Remove the two screws that secure the ACM to the ACM bracket that is welded onto the top of the floor panel transmission tunnel.
6. Lift the ACM from the ACM bracket on the top of the floor panel transmission tunnel and move the unit to the left far enough to access the ACM wire harness connectors.
7. Disconnect the two instrument panel wire harness connectors for the ACM from the ACM connector receptacles on the right side of the module. To disconnect the large 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.

8. Remove the ACM from the left side of the floor panel transmission tunnel.

INSTALLATION

WARNING:
- ON VEHICLES EQUIPPED WITH AIRBAGS, DISABLE THE SUPPLEMENTAL RESTRAINT SYSTEM BEFORE ATTEMPTING ANY STEERING WHEEL, STEERING COLUMN, DRIVER AIRBAG, PASSENGER AIRBAG, SEAT BELT TENSIONER, FRONT IMPACT SENSORS, 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 FRONT SUPPLEMENTAL RESTRAINTS. NEVER STRIKE OR DROP 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 FRONT SUPPLEMENTAL RESTRAINT DEPLOYMENT AND POSSIBLE OCCUPANT INJURIES.

1. Position the Airbag Control Module (ACM) to the left side of the floor panel transmission tunnel near the ACM bracket.
2. Reconnect the instrument panel wire harness connectors for the ACM to the ACM connector receptacles on the right side of the module. Be certain that the latches on both connectors and the red Connector Position Assurance (CPA) lock on the large connector are each fully engaged.
3. Carefully position the ACM into the ACM bracket on the top of the floor panel transmission tunnel. When the ACM is correctly positioned, the arrow on the ACM housing will be pointed forward in the vehicle.
4. Install and tighten the two screws that secure the ACM to the ACM bracket that is welded onto the floor panel transmission tunnel. Tighten the screws to 36 Nm (26 ft. lbs.).
5. Install and tighten the ground screw that secures the ground lug on the left rear corner of the ACM housing to the ACM bracket on the floor panel transmission tunnel. Tighten the screw to 12 Nm (105 in. lbs.).
6. From the left side of the floor panel transmission tunnel, carefully position the ACM cover back over the top of the ACM.

NOTE: The integral flange on the left side of the ACM cover is secured to the floor panel transmission tunnel with a short piece of double-faced tape as an assembly aid during the manufacturing process, but this tape does not require replacement following service removal.

7. Reinstall the center console onto the top of the floor panel transmission tunnel.
8. Do not reconnect the battery negative cable at this time. The airbag system verification test procedure should be performed following service of any supplemental restraint system component. (Refer to RESTRAINTS - STANDARD PROCEDURE - VERIFICATION TEST).
