Circuit Operation

Retained Accessory Power (RAP) allows the Radio, Cell Phone and Sunroof to be operated for approximately 10 minutes after the ignition switch is turned off.

When the ignition switch is turned to ACCY or RUN, voltage is applied from the IP Junction Block WSW/RFA Fuse to the Remote Function Actuator (RFA) Module. The RFA Module grounds terminal 86 of the RAP Relay. The RAP Relay energizes, supplying power to the Rear Junction Block RDO/PM Fuse and the SUNRF Fuse (if equipped).

When the ignition switch is turned off, the voltage through the IP Junction Block WSW/RFA Fuse to the RFA Module is removed. The RFA Module continues to ground terminal 86 of the RAP Relay for approximately 10 minutes or until any passenger compartment door is opened. After 10 minutes or if any passenger compartment door is opened the RFA Module removes ground from terminal 86 of the RAP Relay, removing power from the Rear Junction Block RDO/PN Fuse and the SUNRF Fuse (if equipped). The RFA Module receives passenger compartment door status from the Drivers Door Module (DDM) via CLASS 2 Serial Data Line.
