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 time-out limit.

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