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

A door lock switch LOCK or UNLOCK activation

A key cylinder lock/unlock activation

A keyless entry transmitter activation

An automatic door lock activation (Personalization function)

An automatic door unlock activation (Personalization function)

A delayed locking activation (Personalization function)

Door Lock Operation

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.

Driver Door Unlock Operation

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.

Passenger Door Unlock Operation

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
door lock actuator unlock control circuits to voltage. Since the door lock actuator lock control
circuit is at ground potential within the driver switch assembly, the passenger door lock actuator
motors transition to the UNLOCK position.

The door lock actuator unlock control circuits are dedicated control circuits used only for the
passenger door lock actuator motors. 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.

Automatic Door Lock/Unlock

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 .

Delayed Locking

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.

Lockout Prevention

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.

Unlock After Air Bag Deployment

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