Tbc fault

Steelnc · Apr 7, 2013

Tbc fault has been going on and off for the last 35k. Lately it's gotten worse. It's driving me crazy. I read somewhere that cleaning the trailer plug with electrical cleaner will usually clear this up. Bought some and did nothing. Any ideas?

dealer told me i need a new controller when my did the code. I just unplugged it and plugged it back in and it has yet to give me the code again

So you just unplugged the original or put a new one in? If so, Oem? How much $ thanks.

Disconnect your batteries for about 10 minutes or unplug and replug the controller

Mine got bad for awhile like going off every time I hit a slight bump, I un plugged it and plugged it back in and hasn't done it since. If it happens again I'll just unplug the fcker for good.

05 under had some bad controllers but 06 up not so much

I would rather unplug the TBC than unplug the batts and lose memories and go thru adaptive relearn

however I didn't know the TBC had a memory reset ?
