Relay Controlled RAP
The BCM keeps the RAP relay energized during all power modes, except Off-Awake and Crank. The relay is also energized for approximately 10 minutes after shutting the ignition OFF and removing the key, providing no door is opened.
Relay controlled RAP will end when one of the following conditions is met:
- The BCM receives an input from any door ajar or open switch indicating the opening of any door after the ignition key is out of the ignition.IMPORTANT: If the BCM is receiving any door ajar or open signal from those switches when the ignition key is turned OFF, RAP will not initiate.
- The BCM internal timer for the RAP expires after approximately 10 minutes.
- The BCM detects a decrease in battery capacity below a prescribed limit.
Systems powered by the accessory relay during the retained accessory power (RAP) power mode are as follows:
- Power windows
- Sunroof
