TECHNICAL
Subject:
Unwanted Intermittent Door Lock Activation (Reprogram BCM)
Models:
2004 Pontiac Grand Prix
Condition
Some customers may comment that the door locks intermittently attempt to lock while driving, even through they are already locked.
Correction
Normal operation of the door relock system on the 2004 Grand Prix is a little different than other vehicles. For example, if you open and close the door
while the vehicle is in any gear selection other than Park, the doors will not relock until the vehicle reaches 40km/h (25mph). That speed is much higher
than the 11-14km/h (7-9 mph) that most other vehicles are programmed to relock. When diagnosing, be sure the condition is verified with the customer
and the customer understands the relock operation on this vehicle.
If the customer is still sure the door locks are cycling on their own and the concern can be duplicated, reprogram the BCM with an updated software
calibration. This new service calibration was released with TIS satellite data update version 5.5, available May 16, 2005. As always, make sure your
Tech 2(R) is updated with the latest software version.
