I am getting a code U0032 Vehicle Communications Bus A(+) High from the TCM $18.

Anyone ever seen this before? Everything appears to be normal. If i reset it, it comes back instantly.

Any idea?

Thanks

Well it must exist because I am throwing it ;)

I diconnected the TCM and then I just got codes about losing communication with the TCM. I reconnected the TCM and I get the U0032 code again.

Last week I had my transfer case removed, repaired and reinstalled under warranty. I put the truck on the lift to inspect all the wiring and all looks good. I unplugged all the Transmission and transfer case plugs and plugged them all back in, still get the code.

I reprogrammed the ECM with EFI live and it seems to be gone now. Not sure what is up but I'm not too worried about it.

They secretly put SPYWARE in your ECM and you need to put Tin-Foil on your ON-Star antenna now so the men in black do not come after you.....:eek:

Wonder if its like when people pull codes with the predator and it shows a different code than what matches a "Factory" code.

I had looked and could not even match a failure discription like the one you put. I guess if its gone now, really dosnt matter.

Wish they were coming out with the EFI live for the LBZ, of course I already had ordered the new truck when they started looking for people to beta test.
