2013年9月26日 · For probably the last 2 weeks I have gotten U0101 and P0880 codes shortly after starting my truck and letting it warm up. It puts the truck in limp mode, illuminates the CIL and Traction Control light, and the DIC reads "service stabilitrack" "service traction control" and "service park assist."...

2010年2月3日 · The P0880 means the TCM lost power for whatever reason unnaturally, this goes along with the line under your PRNDL going away and being stuck in a limp gear because the TCM is offline, that is also why the ECM set the U0101. Has this happened more than once? Any electrical modifications from stock? Has the TCM ever been messed with?

2010年2月2日 · I began a post about my truck getting the P0880 code (TCM Power Input Signal) and U0101 code (Lost Comm with TCM) in another forum on the DF but didnt get many replys so if any of you could lend me some advice, i would really appreciate it.

I have a '13. 213k miles. Mine threw codes U0101 and P0880. I sent my TCM to Autocomputer Specialist. They "tested it" and said it was OK, charged me $150+ shipping. I checked my wiring harness, no problems with it. Reinstalled my TCM and the codes came back. Took it to Chevrolet. They ran it thru their test equipment. Discovered a bad TCM.

2014年2月25日 · Ive had the tuning for maybe about a month. Today when I started the truck, all the service traction control and other things were gone, the check engine light was still on, throwing a U0101 code and now also a P0880 code. There is now a line under the gear selector and I am also able to drive it now.
