I've never had to replace the BCM, but from what I read, you need to have the BCM programmed to match the options on your car. As far as I know, only the dealer can do that, unless you find someone that has a Tech 2 ( the programmer/diagnostic tool that the dealer uses).

Also, I bet frohara has his airbag warning light on (airbag system is disabled) and a B1001 set ... that will have to be fixed also by the re-programming.

Yes, you are 100% correct. I do have a B1001 code and the air bag warning light is on.

A trip to the dealer is in order.

Thanks for all your help guys.
