When either of the door lock switches are pressed to the unlock position, voltage is applied to the passenger door lock unlock control circuit. Since the lock control circuit is at ground potential, the door lock actuators go to the unlock position.The unlock function can also be accomplished by the BCM supplying voltage to the door lock control circuit by any of the following:
^ A keyless entry unlock transmission
^ An automatic door unlock function - Personalization
