PINPOINT TEST G: THE AUTO-LOCK DOES NOT OPERATE CORRECTLY


G1-G6:






Normal Operation
During auto-lock operation, the smart junction box (SJB) energizes the lock relay based upon input from the door ajar switches, the network message for the PRNDL position, the stoplamp switch input and the vehicle speed signal. The SJB locks the doors when it senses the doors are closed and the vehicle is in motion.
