The power door lock system consists of the following components:

The power door lock system can be controlled by any of the following:

When either of the door lock switches are pressed to the lock position, voltage is applied to the door lock control circuit. Since the unlock control circuits are at ground potential, the door lock actuators go to the lock position.

The lock function can also be accomplished by the BCM supplying voltage to the door lock control circuit by any of the following:

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:

When either of the door lock switches are pressed to the unlock position, voltage is applied to the door lock unlock control circuits. Since the lock control circuit is at ground potential, the door lock actuators go to the unlock position.

The driver door unlock control circuit is a dedicated control only for the driver door lock. This is done so that the driver door may be unlocked by itself using a keyless entry unlock transmission or with an automatic door unlock function - Personalization.

This feature inhibits the power door lock feature when the key is in the ignition, or the ignition is in the RUN/START position and any door is open. This feature can be overridden by continuous activation of any power door lock switch for 3 seconds.

This feature will unlock the doors when the key cylinder unlock switch has been closed for 1.5 seconds, or closed twice within 3 seconds.

Vehicles equipped with the automatic door lock option are factory programmed to have the automatic door lock feature lock all the doors when the following conditions are met:

This automatic door lock function will only occur once per ignition cycle unless, any door jamb switch input changes state to active and back to inactive. Then the automatic door lock feature will lock all doors again.

Once the automatic door lock feature has locked the doors, the automatic door lock feature will then unlock all the doors once the vehicle is shifted back into the PARK position or if the ignition key is removed from the ignition switch. The automatic door unlock feature can be programmed to unlock the driver door only if desired.

This feature will unlock the vehicle doors, 15 seconds after air bag deployment.
