Side - B-Pillar
On vehicles equipped with the high voltage system, disconnecting the 12-volt battery negative cable alone will not power down the 12-volt system. You must perform the 12-volt Power Down procedure before proceeding. Failure to follow these instructions may result in possible serious or fatal injury.
To avoid serious or fatal injury on vehicles equipped with airbags, disable the Supplemental Restraint System (SRS) before attempting any steering wheel, steering column, airbags, airbag curtains, knee blocker, seat belt tensioner, impact sensor or instrument panel component diagnosis or service. Disconnect the IBS/negative battery cable assembly from the negative battery post, 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 SRS. Failure to take the proper precautions could result in accidental airbag deployment.
To avoid serious or fatal injury, 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 Supplemental Restraint System (SRS) components. 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 side SRS component deployment.
- Adjust the driver or passenger side front seat to its most forward position for easiest access to the B-pillar.
- Perform the 12-Volt Power Down procedure. Refer to ELECTRIC VEHICLE CONTROL SYSTEM, STANDARD PROCEDURE .
- Remove the trim from the inside of the lower right or left B-pillar (2). Refer to PANEL, QUARTER TRIM, REAR, REMOVAL .
- Remove the nut (1) that secures the side impact sensor (3) to the weld stud on the lower B-pillar.
- Disconnect the body wire harness connector (4) from the sensor connector receptacle.
- Remove the sensor from the B-pillar.
