Impact Sensor: Service and Repair

REMOVAL

WARNING:
- TO AVOID PERSONAL INJURY OR DEATH, ON VEHICLES EQUIPPED WITH AIRBAGS, DISABLE THE SUPPLEMENTAL RESTRAINT SYSTEM BEFORE ATTEMPTING ANY STEERING WHEEL, STEERING COLUMN, AIRBAG, SEAT BELT TENSIONER, IMPACT SENSOR, 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.
- TO AVOID PERSONAL INJURY OR DEATH, NEVER STRIKE OR DROP THE SIDE IMPACT SENSOR, AS IT CAN DAMAGE THE IMPACT SENSOR OR AFFECT ITS CALIBRATION. THE SIDE IMPACT SENSOR ENABLES THE SYSTEM TO DEPLOY THE SIDE CURTAIN AIRBAGS. IF AN IMPACT SENSOR IS ACCIDENTALLY DROPPED DURING SERVICE, THE SENSOR MUST BE SCRAPPED AND REPLACED WITH A NEW UNIT. FAILURE TO OBSERVE THIS WARNING COULD RESULT IN ACCIDENTAL, INCOMPLETE, OR IMPROPER SUPPLEMENTAL RESTRAINT DEPLOYMENT.

1. Disconnect and isolate the battery negative cable. Wait two minutes for the system capacitor to discharge before further service.
2. Remove the trim paneling from the interior of the front door step well.

Side Impact Sensor Remove/Install:

3. Disconnect the vehicle wire harness connector from the side impact sensor connector receptacle.
4. Remove the two screws that secure the side impact sensor to the forward vertical surface of the step well.
5. Remove the side impact sensor from the step well.

INSTALLATION
1. Position the side impact sensor to the forward vertical surface of the step well. Be certain that the arrow on the sensor housing is pointed toward the outboard side of the vehicle.
2. Install and tighten the two screws that secure the side impact sensor to the step well.
3. Reconnect the vehicle wire harness connector for the side impact sensor to the sensor connector receptacle.
4. Reinstall the trim paneling to the interior of the front door step well.
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.
