Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Module, Body Control (BCM): Removal
To avoid serious or fatal injury on vehicles equipped with airbags, disable the Supplemental Restraint System (SRS) before attempting any steering wheel, steering column, airbag, Occupant Classification System (OCS), 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 SRS. Failure to follow these instructions may result in accidental airbag deployment.
- Disconnect and isolate the negative battery cable. If equipped with an Intelligent Battery Sensor (IBS), disconnect the IBS connector first before disconnecting the negative battery cable.
- Remove the steering column opening cover from the instrument panel. Refer to COVER, STEERING COLUMN OPENING, REMOVAL .
- Remove the left lower A-Pillar extension/sill plate trim.
- Disconnect all the wire harness connectors (1) from the Body Control Module (BCM).
- Remove the fasteners (1) that secure the BCM brackets to the instrument panel carrier, outboard of the steering.
- When removing the BCM, disconnect the wire harness connectors (1) from the back of the BCM.
- Remove the BCM to bracket mounting fastener (1).
- If necessary separate the BCM from the bracket.
