Relay Control of Retained Accessory Power (RAP)

Retained Accessory Power (RAP) is a vehicle power mode that permits the operation of selected customer convenience items after the ignition switch is turned OFF. These selected items will remain in operation until a passenger compartment door is opened or until the RAP function timer reaches its shut-off limit.

The BCM closes the RAP relay in either the RAP function as described above or if the BCM detects a RUN/ON or accessory power mode. This provides power for the following:
^ The power windows
^ The sunroof control module (if equipped)

The BCM opens the RAP relay to end the RAP function when it ends the RAP function as outlined in the previous text.
