• The transmission was in gear and speed is above
zero.
• The transmission in park or neutral and speed
is zero.
• Any door (excluding liftgate) opens.
DOOR LOCK INHIBIT
The BCM cancels out the door lock switch actua-
tion, when the key is in the Ignition Switch and
either front door is open.
Pressing the key fob RKE lock/unlock under these
conditions results in normal lock/unlock activation.
CENTRAL LOCKING
If equipped with Vehicle Theft Security System
(VTSS), all the doors can be locked with the key by
using any of the door lock cylinders. Turning the key
to the lock position will lock all the doors.
DOOR LOCK CIRCUIT PROTECTION
The door lock system is protected by a 40 amp fuse
located in the IPM. The BCM receives lock/unlock
input and will turn on the appropriate drivers and
provide a voltage level to the door lock motor for a
specific time. The IPM is located along the side of the
vehicle battery in the engine compartment.
