BCM????

Has anyone else ever had problems with a body control module going bad on them? I have a 2008 tundra with the 4.7 in it and I believe that I have a bad BCM

 

The BCM is the only item left that has not been tested or replaced that could cause the pwr wdw and pwr locks on the back doors to not work. It is the only thing that I can think of that could be causing my issues with the pwr wdw and pwr locks.

 

What are the symptoms and what have you checked?

 

^^ What they said +1.
I'm looking at the schematics, and there's more than just the Main Body ECU that could be inop.
If you want help, symptoms and a list of things already verified will let us help you. Without those things, we're all just guessing.

EDIT: See this thread.

The midwesterner- I have issues with the pwr window and pwr locks. The front works fine the back does not work at all. Master switch is good. Actually just put a brand new one in to be sure. Have checked to verify I have par at master switch, on both sides of the connectors under the fuse box in driver floorboard, and a few other things I have done. The only thing that I can think of that will cause this would be the BCM or otherwise referred to as main body ECU. Any suggestions

 

Stevj- I listed some of the things I checked on last post. Really just need help locating the Main Body ECU or otherwise referred to as the BCM. Can you tell me where I can find this on a 2008 tundra?

 

Yep. It's under the dash very near the flasher relay.
