Remote Keyless Entry Exterior Lamp Illumination

When the Remote Function Actuator (RFA) module receives a door LOCK or UNLOCK command from the remote function actuator transmitter, the RFA will send a class 2 message to the BCM in order to activate the Park Lamps Relay. The BCM must have inputs that indicate that the ignition switch is OFF, both doors are closed, and the ambient light sensor indicates low light conditions. The BCM will flash the park lamps, side marker lamps, and tail lamps once when the RFA module receives a door LOCK command from the remote function actuator transmitter, and twice when the RFA module receives a door UNLOCK command from the remote function actuator transmitter.
