Description & Operation: Notes
WARNING:
Before servicing steering column or related components, see SERVICE PRECAUTIONS and DISABLING & ACTIVATING AIR BAG SYSTEM in AIR BAG RESTRAINT SYSTEM article.
NOTE:
On some vehicles, the power door lock system is integrated with the Remote Keyless Entry (RKE) system. For information on RKE, see REMOTE KEYLESS ENTRY SYSTEM
article.
Door locks will lock and unlock in unison when either door lock switch is pressed. Each lock can also be operated manually from locking knob. Locks are operated by reversible actuators that receive voltage from door lock relay assembly's 2 built-in relays. These relays operate to energize the actuators by applying voltage to one of the terminals and ground to the other terminal. To reverse actuators, polarity to terminals are reversed.
Door lock switches are usually closed momentarily. If switches are held closed, a circuit breaker in each actuator will open to protect against damage. Circuit breaker resets only after voltage is removed from actuator.
