Module, Body Control: Installation
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.
- Snap the Body Control Module (BCM) (2) into the mounting brackets.
- Install and tighten the screws (1) that secure the BCM to the mounting brackets. Tighten the screws to the proper torque specification. Refer to TECHNICAL SPECIFICATIONS .
- Position the BCM and the yoke-like BCM mounting brackets (4) to the instrument panel support structure outboard of the steering column as a unit.
- Install and tighten the screws that secure the BCM mounting bracket to the instrument panel support structure. Tighten the screws to the proper torque specification. Refer to TECHNICAL SPECIFICATIONS .
- Reconnect up to eight wire harness connectors to the connector receptacles of the BCM. Six integral connector receptacles are located on the rearward facing surface of the BCM housing and two are on the forward facing surface.
- Reinstall the steering column opening cover onto the instrument panel. Refer to KNEEBLOCKER, INSTALLATION .
- Connect the battery negative cable.
- Perform BCM module programming with the scan tool. Refer to MODULE, BODY CONTROL, MODULE PROGRAMMING .
If this Electronic Control Unit (ECU) is being replaced with a new unit, a diagnostic scan tool MUST be used to align the PROXI configuration data into the new ECU. Follow the routine outlined in the diagnostic scan tool for PROXI Configuration Alignment under Body Control Module (BCM) Miscellaneous Functions menu.
