INSTALLATION

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, 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.
