RAP Relay Feedback

Range: ON/ OFF
The RAP feedback information refers to the operation of the retained accessory power (RAP) circuit. ON displays whenever the BCM turns ON the RAP relay.

The RAP relay then allows the following components to operate:
^ The radio
^ The power windows
^ The overhead console
^ The sunroof with the ignition key removed or in the OFF position and with all of the doors closed.
