The Power Door Locks/Remote Keyless Entry control system provides several functions. The driver operates the vehicle door locks and rear window release from outside the vehicle using a hand-held radio transmitter. The transmitter sends coded signals to the remote control door lock receiver. The remote control door lock receiver detects and decodes the signal from the transmitter. The remote control door lock receiver issues signals to the body control module (BCM) through a serial data link. The BCM actuates relays to lock and unlock the doors and liftgate. The BCM can also release the liftglass. The power door lock switches provide manual control of the door locks. Refer to Release Systems or information on the operation of the rear window release system.
