Retained Accessory Power (RAP) Circuit Description

The retained accessory power (RAP) system allows the following components to operate for approximately 10 minutes after the ignition switch is turned off:
- The radio
- The windows
- The sunroof (if equipped)
- The cell phone (if equipped)

When the ignition switch is turned to the ACCY or the RUN position, voltage is applied from the IP fuse block WSW/RFA fuse to the Remote Function Actuator (RFA) module. When the RFA module RAP relay control output grounds the RAP relay, the RAP relay energizes and supplies power to the RDO/PH fuse and the SUNROOF fuse (if equipped).

When the ignition switch is turned to the OFF position, the voltage from the IP fuse block WSW/RFA fuse to the RFA module is removed. The RFA module continues to ground the RAP relay control output until either 10 minutes pass or any passenger compartment door opens. The RFA module receives a passenger compartment door status from the Drivers Door Module (DDM) through the class 2 serial data line. If either event occurs, power is removed from the rear fuse block RDO/PH fuse and the rear fuse block SUNROOF fuse (if equipped).
