2004 Buick Regal BCM VATS? in Module Repair/Swapping Posted Sunday at 11:35 PM This particular car was a later model car that does not utilize a VATS module, but stores the information in the BCM. The BCM was bad in the car. As soon as you turned the key on, the security light as well as other dash light would start blinking, as well as one of the needles on either the tach or speedometer. (I don't remember which) Also, I could hear a clicking under the dash that was in rhythm with the cluster blinking. I traced it to the BCM, and a relay on the board. Incidentally, this cycling relay coincided with a no run/no start condition. I ended up advising the customer to get a new BCM from Oh'Really. When the new BCM was plugged, everything seemed normal except the security light flashing. I could not get the Tech2 to program the BCM. I did use the Tech2 to do a theft system relearn, and as soon as it went through the 10 minute wait, the security light went out, I cycled the ignition, and she fired up. The BCM still would not program with tech2. It kept giving a no communication message. Put the 608 on it and noted that the unit was actually a refurb. It still contained the VIN from the donor vehicle. Surprisingly, the 608 allowed me to edit the VIN in the BCM. Then it showed success programming the BCM. When I finished the interior lights and the automatic windows did not work. I had the following 2 codes. I referred the customer to an auto electrician, and advised them that it is possible that one of the 2 diagnostic codes could have been responsible for frying the original module.
