Power Door Locks

WARNING: This page is about a different car, the 2004 Dodge Intrepid, 2004 Chrysler Intrepid, 2004 Chrysler Concorde, and 2004 Chrysler 300M. However, it is still accessible from the selected car via links, so may be relevant.

The Body Control Module (BCM) actuates the power door lock relays when a door lock switch is activated. If the door lock switch is pressed for longer than eight consecutive seconds, the BCM will de-energize the door lock relay.

The system includes an Automatic Door Locking feature. The vehicle is shipped with the system enabled. When the system is disabled the door locks will work by use of the door lock switches and the Remote Keyless Entry System only. When the Automatic Door Lock System is enabled the BCM will automatically lock all the doors when all of the conditions below are met:

All doors are closed.
The vehicle speed exceeds 15 +/- 1 mph.
The throttle position sensor tip-in is greater than 10 +/- 2 degrees.

The DRB III(R) scan tool is used to enable/disable the automatic door lock system. Refer to the BODY DIAGNOSTIC PROCEDURES - CONCORDE, 300M & INTREPID . They are also customer programmable. Refer to Owners Manual for customer programming procedures.

The BCM will automatically re-lock all doors if the above conditions are met and if any of the doors become ajar and then closes again.

The power lock motors are also equipped with a thermal protection system which prevents the motors from burning out. The motors may chatter if they are continuously activated.
