All,

With the help of this forum, I was able to isolate my excessive current draw to the Body Control Module. With its fuse in place, the system draws 200 milliamps. With its fuse removed, the system draws 9 milliamps.

Not so helpfully, the description of the BCM is "connects several circuits and switches to other circuits and switches." I could always replace the BCM, but I have a suspicion that the problem is in one of the user operated switches. Can anyone point to a circuit diagram for the BCM? I'd like to trace to all of the endpoint switches if possible to do more troubleshooting.

If you have other ideas for troubleshooting from here, please let me know.

Thanks.

 

the diagram you need is a power distribution diagram. this will show every circuit that is supplied power from the bcm.

 

Thanks for the tip.

I got the electrical diagrams and determined which circuits and relays fed into it. I pulled each of those relays and fuses but the current draw stayed the same ... around 200 milliamps.

The next step I can think of would be to replace the BCM itself, but I don't have the dealer's tool needed to program it.

Any other thoughts?

Thanks,

Jeff
