The power door lock system consists of the following components:

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

When the driver switch assembly detects a transition of either its own door lock switch, the passenger door lock switch or the key cylinder switch to the LOCK position, it switches the door lock actuator lock control circuit to voltage. Since the lock actuator unlock control circuits are at ground potential within the driver switch assembly, the door lock actuator motors transition to the LOCK position.

When the driver switch assembly detects a transition of either its own door lock switch, the passenger door lock switch or the key cylinder switch to the UNLOCK position, it switches the driver door lock actuator unlock control circuit to voltage. Since the door lock actuator lock control circuit is at ground potential within the driver switch assembly, the LF door lock actuator motor transitions to the UNLOCK position.

The driver door lock actuator unlock control circuit is a dedicated control circuit used only for the driver door lock actuator motor. This is done so that the driver door may be unlocked by itself using a keyless entry transmitter or an automatic door unlock function, if programmed.

This is done so that the driver door may be unlocked separate from the passenger doors using a keyless entry transmitter or an automatic door unlock function, if programmed.

The automatic door lock/unlock function is a vehicle personalization feature with the following 6 programmable modes of operation:

1. The automatic door lock feature is disabled.
2. The automatic door lock on shift out of PARK feature is disabled.
3. All of the doors lock when the vehicle is shifted out of PARK with the ignition ON, and only the driver door unlocks when the vehicle is shifted into PARK.
4. All of the doors lock when the vehicle is shifted out of PARK with the ignition ON, and all of the doors unlock when the vehicle is shifted into PARK.
5. All of the doors lock when the vehicle is shifted out of PARK with the ignition ON, and only the driver door unlocks when the key is removed from the ignition.
6. All of the doors lock when the vehicle is shifted out of PARK with the ignition ON, and all of the doors unlock when the key is removed from the ignition.

The automatic door lock function can only be enabled by the body control module (BCM) if the driver, front passenger, and rear door switches are in an Inactive state (closed). For information on programming the automatic door locks, refer to Vehicle Personalization .

The delayed locking function is a vehicle personalization feature that is intended to allow the doors to be locked while passengers are exiting the vehicle. When delayed locking is in Active Mode, the body control module (BCM) will delay locking of the vehicle doors for 5 seconds after all of the doors have been closed. The delayed locking function will be overridden if the BCM receives a door UNLOCK input or a key in ignition input.

This function is intended to prevent the vehicle operator from locking the doors if the key is left in the ignition and any vehicle door is open. The lockout prevention function can be overridden by the body control module (BCM) if the BCM receives a remote lock input or if the door is manually locked.

This feature will unlock all of the vehicle doors 15 seconds after air deployment.
