WARNING: This page is about a different car, the 2002 GMC Sierra, 2002 GMC Cab & Chassis Sierra, 2002 Chevrolet Silverado, and 2002 Chevrolet Cab & Chassis Silverado. However, it is still accessible from the selected car via links, so may be relevant.
RAP is a vehicle power mode that permits the operation of selected customer convenience items after the ignition switch is turned OFF. These selected items will remain in operation until a passenger compartment door is opened or until the RAP function timer reaches its shut-off limit.
The BCM turns OFF the RAP function and de-energizes the RAP#1 relay when one of the following conditions are met:
- The BCM senses the opening of any door or the liftgate.
- The BCM detects a decrease in battery capacity below a prescribed limit.
- The BCM receives a message from its internal timer indicating the end of the RAP period after 20 minutes.
- The transition from OFF to RUN/ON of the ignition switch.
