The Retained Accessory Power (RAP) system allows selected accessory circuits, such as radios or power windows, to remain powered even when the ignition switch is turned off. These accessory circuits will continue to be “live” until the system grounding relay is activated.
RAP stands for Retained Accessory Power. It is a feature found in many vehicles, including Chevy Silverado and Malibu. The RAP relay keeps voltage applied to various components, such as the sunroof, power windows, door locks, radio(s), and OnStar, even with the ignition off and all doors closed. This feature allows the stereo and select accessories to operate for some time after the ignition key has been switched off.

How Does Retained Accessory Power Work?
The retained accessory power module takes control of any accessory driven by its relay. When the key is turned on, the relay is closed, providing power to the selected accessory circuits. Even after turning off the key, the RAP system allows these circuits to remain powered for a predetermined time, ensuring continued operation of the accessories.
Many GM vehicles have RAP, which enables the radio to remain on in the car for up to ten minutes after the key is turned off. Once the door opens, the RAP system is disabled, and the power is cut off from the accessories.
