General Information

This vehicle is equipped with a Body Control Module (BCM). The BCM performs multiple body control functions. Several of the vehicle systems are directly connected to the BCM such as the following systems:
^ The Retained Accessory Power (RAP)
^ The audible warnings
^ The interior lighting
^ The door locks
^ The keyless entry
^ The content theft deterrent

These systems are controlled by the BCMs outputs. The BCM controls its outputs based upon the input information obtained from the sensors and switches that are directly connected to the BCM. The BCM evaluates the input information and controls the body systems by commanding an output on or off.
