What does our cars have?? I thought we had a BCM and PCM, but everytime I use the term BCM with a person they keep correcting me and saying I must mean TCM.

BCM=body control module, ???????????? what does it do?
TCM=transmission control module, ????????????

WFT??

I am very confised and someone is using it against me. Can someone PLEASE help me out?

ChevyMgr

We have a:

BCM = Body Control Module.
ECM = Engine Control Module.
TCM = Transmission Control Module.
PCM = Powertrain Control Module (Used prior to our vehicles which was basically an ECM and a TCM together).
EBCM = Electronic Brake Control Module (For ABS equipped vehicles).

And there are others that aren't important.

Thanks!

GDZHHR

so which one is part# 24234503

Holy cow. You're working backwards. There are multiple pn's for each of the modules that ChevyMgr called out, depending on year, trim level, motor, trans, production run, etc.

GDZHHR

Yeah I know, I just found the invoice. Plus I wanted to know the other stuff too.

• LFWCM = left front window control module
• RFWCM = right front window control module
• LRWCM = left rear window control module
• RRWCM = right rear window control module
• FWWCM = front windshield wiper control module
• RWWCM = rear windshield wiper control module
• ARDCM = acoustical reception device control module
  ... which includes sub-modules
  • AMBCM = amplitude modulation band control module
  • FMBCM = frequency modulation band control module

... OK, I'm tired of typing, and the list is getting silly

ChevyMgr

I think a TCM, by an internet search. I wont' know until Monday because I have the weekend off. Yay!!

If it is mounted where the ECM is it's a TCM if it's a BCM it's the interior electrical center (fuse box).

Mike give me your last 8 of the VIN and I will find out what part number BCM and TCM you should have.

GDZHHR

Thanks, I got what I need to know!

So my TCM got fried, not my BCM.
