Firebird V8-5.7L VIN G (2001)
Accessory Delay Module: Description and Operation
The Body Control Module (BCM) monitors the ignition switch position, battery condition and passenger compartment door status to determine whether
Retained Accessory Power (RAP) should be initiated. If the ignition switch transitions from RUN/ON to OFF, the battery level is within the acceptable
range and the passenger compartment doors are closed, the BCM closes the internal RAP relay. The RAP relay then provides power to the:
^
Power windows
^
Power folding top
^
Radio.
The BCM module turns OFF the RAP function and opens the internal RAP relay when one of the following conditions are met:
^
The body control module senses the opening of a door in the passenger compartment
^
The body control module receives a message from its internal timer indicating the end of the RAP period after 10 minutes
^
The transition from OFF to RUN/ON or ACC of the ignition switch.
