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.

When the BCM is in the RAP function as described above, it closes the RAP and the CONT PWR relays. This provides power during the RAP period for the following:
^ power windows
^ power sunroof (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.
