Door Lock System Controls
The power door lock system can be controlled by any of the following:
Door Lock and Unlock Operation
When a door lock switch is activated in the lock or unlock position the BCM will receive a ground signal on either the door lock switch lock or unlock signal circuits.
The BCM, upon receipt of a lock switch lock or unlock signal, will supply battery voltage to the door lock actuator lock or unlock control circuits. Since the opposite side of the lock actuator is connected to ground through the other lock actuator control circuit, the doors, fuel filler door and liftgate will then lock or unlock as commanded.
The following three circuits are used to operate the lock:
The driver door lock actuator is isolated so it can be unlocked by itself using the keyless entry transmitter.
Automatic Door Lock Operation
This feature can be personalized to driver preference.
The BCM will automatically lock the vehicle doors if the following conditions exist:
The BCM will then unlock the doors when vehicle is shifted back into Park.
Delayed Locking Operation
With any door open and a door lock switch is activated in the lock position, the BCM will give three audible chimes. When the door is closed, the BCM will cycle the internal door lock relay to lock the doors after approximately five seconds. This feature can be overridden by activating the door lock switch a second time and the doors will lock even with a door open.
Lockout Prevention Operation
The BCM will lock all doors and unlock the driver door with a door lock switch lock activation if a vehicle door is open and the ignition key is fully inserted in the ignition. The lockout prevention feature can be overridden if a lock command is received from the keyless entry system.
