1997 Eagle Vision V6-201 3.3L VIN T SFISECTION Power Door Lock System
The door lock switches provide a variable amount of voltage through the multiplexed (MUX) circuit to the BCM Depending upon that input and various conditions that must be met (i.e., door lock inhibit, etc.). the BCM will determine the action to be taken and activate the proper relay for approximately 250 to 350 msec.
Other power door lock features:
RKE (Remote Keyless Entry) - This feature allows locking and unlocking of the vehicle door(s) by remote control using a hand-held transmitter to activate a radio receiver (RKE module). If the vehicle is equipped with vehicle theft security system, it will also arm or disarm that system. The transmitter can also unlock the trunk while the vehicle is in park and the ignition off. The system was changed in model year 1995 requiring the trunk release button to be pressed twice to prevent accidental opening of the trunk. The module is capable of retaining two (2) transmitter codes. To program the transmitter see Body and Frame/Locks/Keyless Entry.
Door Lock Inhibit - When the key is in the ignition and the left front door is open, all door lock switches are disabled. The unlock switches are still functional. This protects against locking the vehicle with the keys still in the ignition.
Automatic Door Locks - This feature can be enabled or disabled by using either the DRBIII or the MDS machine. When enabled, all the doors will lock when the vehicle reaches a speed of 15 mph and all doors are closed. If a door is opened and the vehicle slows to below 15 mph, the locks will operate again once all doors are closed and the speed is above 15 mph. This feature is not available with the 1993 body control module.
