Operation CHARM: Car repair manuals for everyone.

Last Door Closed Locking

The BCM activates the last door closed locking feature when these conditions are met:
^ A vehicle door is open (closed circuit in CKT 394 or CKT 395.
^ The key is removed from the ignition switch, thus disabling lockout prevention (open signal in CKT 80).
^ Pressing lock once on a door lock switch. Upon pressing lock, the BCM sounds the chime 3 times. This provides feedback indicating that the last door closed locking feature is active 7 seconds after all doors are closed, the BCM locks all doors.

To cancel this feature:
^ Press unlock on a door lock switch, or keyless entry transmitter.
^ Turn the ignition switch to the accessory or on position.

To override this feature: Press lock twice. The BCM locks all door immediately with a door still open.
