Explain The BCM To Me Please
What exactly does the BCM do? What's the difference between the computer and the BCM? How can your BCM go bad and not your PCM? I would think that if water got into that area, then both would be ruined. :confused:

Re: Explain The BCM To Me Please (CandaceBell)
Before you replace the BCM, try cleaning the connector first. This connector gives people a lot of problems when a small amount of corrosion gets on it. I had an engineer at the factory tell me one time that about 95 % of the modules returned to them had nothing wrong with them. the dealers just pull the old one out and put a new one in. When they break the connector and replace it they clean off the little corrosion causing the problem. Problem fixed and a good module gets scrapped. Not saying this is always the case, but it's easy to to clean a connector first and try it than to pay the money for a new module. If they really get flooded due to an A/C condensate leak than they can get corroded inside but I'd still try the connector first if the car isn't under warranty and the money for a module was coming out of my pocket.

Do you know where it is located and how easy is it to get to?

Damn that was easy enough. I have seen it a few times. Does it hurt to disconnect it nad reconnect it?

Re: Explain The BCM To Me Please (minivette)
Yep, you were right :)
I got my car back yesterday...with a broken plastic/carpet covering under the passenger side dash :mad I WILL NOT EVER take my car back to a dealer unless I absolutely have to (which...I did have to) Anyway, they replaced the BCM and the EC...? Along with the relay something...? Car seems to be alright, although I still have to figure out how to stop the air conditioner from leaking, and my 3rd brake light is still the only light showing up when I brake :confused:
But as far as the car running, it seems to be alright :)
Oh, one more thing, 1st gear along with Reverse REALLY like to jump back into neutral. I've been told this is pretty common...? If I go to 1st, then Reverse, it's usually alright...
