Side Impact 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 SIDE IMPACT AIRBAG CONTROL MODULE CONTAINS THE IMPACT SENSOR, WHICH ENABLES THE SYSTEM TO DEPLOY THE SIDE CURTAIN AIRBAGS. NEVER STRIKE OR DROP THE SIDE IMPACT AIRBAG CONTROL MODULE, AS IT CAN DAMAGE THE IMPACT SENSOR OR AFFECT ITS CALIBRATION. IF A SIDE IMPACT 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 SIDE CURTAIN AIRBAG DEPLOYMENT AND POSSIBLE OCCUPANT INJURIES.

1. Adjust the front seat to its most forward position for easiest access to the lower B-pillar trim.
2. Disconnect and isolate the battery negative cable. Wait two minutes for the system capacitor to discharge before further service.
3. Remove the lower trim from the inside of the B-pillar.

1. Position the Side Impact Airbag Control Module (SIACM) and its mounting bracket to the sill panel as a unit.
2. Loosely install the four screws that secure the SIACM mounting bracket to the sill panel at the base of the B-pillar.
3. Tighten the four screws that secure the SIACM mounting bracket to the sill panel in the following sequence: upper front, upper rear, lower front, lower rear. Tighten the screws to 12 Nm (105 in. lbs.).
4. Engage the body wire harness retainer to the tab on the SIACM mounting bracket.
5. Reconnect the body wire harness connector for the SIACM to the module connector receptacle.
6. Reinstall the lower trim onto the inside of the B-pillar.
7. 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).
