Default Possible BCM Issue??????

my 2000 coupe has what i think could be a short in the BCM. The DIC does NOT work. it displays the odometer at all times. The buttons to change the DIC do absolutely nothing. I had a local autoshop plug a computer in to see if it was tripping any codes and i was told it is showing a ton of codes. This is why i am inclined to think it is a short in the BCM.

Anybody had any experience with this or any suggestions? I'm trying to see what i can figure out prior to paying the dealer price to look into it!

Sounds like a problem with the IPC...NOT the BCM.

Is there a way to test to see if it's the BCM or the IPC?

I'm curious as to why you suspect the BCM? The DIC buttons, odometer, etc....are all controlled by the IPC.

The amount of codes that came back when i had the computer hooked up led me to believe it was a BCM issue.

I'm not sure. The mechanic who did it for me said there were pages of codes being sent from the BCM. My headlights also blink quickly with no bulb out, i suspect this is also controlled by the BCM?

Headlights blink quickly?? Do you mean "turn signals" blink quickly?

Either way, you need to buy a scanner, so you can post your codes. It's much easier to troubleshoot, when you have all the codes.

I did mean turn signals. It just seems like regardless of the code if it's throwing that many fromt he BCM there has to be a problem. But then again i'm not well trained in the electrical departement

Anybody in the South Florida area good with this stuff that would be willing to give me a hand?????

Have you pulled up the toe kick in the passenger footwell to see if the aluminum box the BCM board is in has water stains or white oxidation on the aluminum???

Is there moisture inside the IP fuse box????

Not a replacement for having codes but it might be a starting point about what could be going on.
the carpet doesn't feel wet or have signs of stains...i'll have to look at the BCM and see if there is oxidation. At the risk of sounding like a newbie (because i am) is the BCM just up under the glove box or is it in the side kick panel? What is the easiest way to access it?

Thanks again for all the input!

No oxidation on the BCM or moisture in the area. Could this all be a result of the MFS???
