INSTALLATION

WARNING: To avoid serious or fatal injury on vehicles equipped with airbags, disable the supplemental restraint system before attempting any steering wheel, steering column, airbag, occupant classification system, 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.

NOTE: Before replacing a Body Control Module (BCM), use a diagnostic scan tool to retrieve the current settings for the many BCM programmable features including electronic pinion factor (tire size), cabin equalization curve (audio system architecture), country code and Remote Keyless Entry (RKE) system preferences. These settings MUST be programmed into the replacement BCM using the diagnostic scan tool before returning the vehicle to service. A new BCM is shipped in default mode that may prevent proper speedometer indications and the availability of numerous electronic features until it has been properly programmed. Refer to the appropriate diagnostic information.




1. Position the Body Control Module (BCM) (2) to the Junction Block (JB) (3) and reconnect them at the JB/BCM interface connector.

2. Install and tighten the four screws (1) that secure the BCM to the JB. Tighten the screws to 2 Nm (20 in. lbs.).

3. Reinstall the Junction Block Module (JBM) onto the instrument panel end bracket.

4. Reconnect the battery negative cable.

NOTE: If the Body Control Module (BCM) is replaced with a new unit on a 2007 model year vehicle, in addition to setting the programmable features, a diagnostic scan tool MUST be used to update the model year of the replacement BCM from 2006 to 2007. Follow the programming steps outlined in the diagnostic scan tool for Update Model Year to 2007 found under Miscellaneous Functions for the BCM/Body Control Module menu item.
