Operation CHARM: Car repair manuals for everyone.

Lockout Prevention

The BCM does not lock the vehicle doors when you press LOCK on either door lock switch with the lockout prevention feature active.

The BCM activates the lockout prevention factor if the following conditions exist:
^ The driver's door is open.
This causes a ground signal in CKT 159.
^ The key is fully inserted in the ignition switch cylinder.
This causes a ground signal in CKT 80.

The BCM disables the following automatic door lock features when the lockout prevention feature is active:
^ All door lock
^ Last door closed locking
^ Key cylinder unlock
^ Keyless entry system unlock (if equipped with RPO AUO)
