U0101: Top reason is almost always a loose connector on the TCM 99% of the time!!! This bulky connector sits vertically on the TCM thus loosening with time between the cable harness and the TCM. Inspect, clean and secure the connection is one of the best first steps ever.

I had one years ago on a 1982 Mitsubishi Lancer Turbo. This car was an ex Rally car and the owner complained that he could not get it to start. We rigged a bypass so he could get the fuel pump to work. At the weekend we later discovered that the fuel supply connector at the ECU had drifted back away from proper contact with the pin. Turns out he had been swapping ECUs just before it got its problems. Nowadays at my age I always use a bright light and magnifying glass to inspect the ECU plugs.

[@GoTechTraining]

Hey Bigcliffe, when I was at factory training for KIA, they told us the ECU connector is only intended to come apart 3 times. Any more than that and it should be replaced. Crazy but it makes sense! Mike Becker, Senior Instructor

[@bigcliffe]

@@GoTechTraining Now that is interesting.My brother had a 1986 Mitsubishi Mirage Turbo that we spent lots of time and money on to get that car to do a 13.8 second 1/4 mile time. The problem was that the wire harness was the weak point of that car. The heat of the turbo and the high under bonnet temperatures made me think that there should have been available as a spare a full engine to ECU harness.

@@GoTechTraining all plugs/outlets have max cycle count which varies widely, 3 seems awfully low though.

[@davidb.fishburn9338]

@GoTech Mike, I've run into that kind of problem, with my own car, a 2004 Dodge Neon R/T, with a cam sensor issue. Kept getting the P0340 code, checked the wiring and replaced the sensor. Later figured out that the problem was the tabs inside the pins in the connector. The tabs had spread, causing an intermittent contact issue. It didn't help that the wiring harness was moving when the engine moved under acceleration. I simply pushed the tabs back in, fixed the issue for good, That was a few years ago. Have not had any cam sensor issues since. It is likely the same issue with this issue, and why the pin feels loose when the backprobe pin was inserted. Another issue that i've found is that sometimes the pin will not be inserted all the way into the connector so that it gets locked in, and that causes issues like this. When the backprobe pin was inserted, it pushed the pin in far enough to lock it in and make better contact with the other side.

[@jgunther3398]

Check the connector before taking the harness apart, on the basis of looking for the easy things first. Plus, the connector is going to be 1000x as likely as the splice since it's a lot more mechanically complicated. If both sides of the connector have a pigtail you can often test continuity through the connector which helps too

[@Fluffybunnys0]

Amazing video it really helps to know what probably going to be done at the auto electricians in town with my ve commodore to find the problem I have with a pending U0100/P0700 fault codes

[@darrylhowe1465]

Deja Vu. Our shop encountered this exact same problem on this exact same vehicle. All testing was initially done using the "back probing" method but every test showed no problem. To make matters worse, it was an intermittent problem. It would work great for a while then error out. I made the call that it must be an intermittent bad TCM, replaced the module, and the car drove fine ... for a while, then the issue returned (yes ... I ate the cost of a TCM). We switched to the "vampire tap" method for continued testing and that's when we found the problem. We were not able to find a used connector and had to replace the engine harness.

[@GoTechTraining]

Hey Darryl, ahh the "vampire tap" I like that. I may use that in the future! Crazy that it was the same car, same issue...wonder if it's common on these!? I ended up with an "EBAY" used connector. Seems to have done the job though. Mike Becker, Senior Instructor

[@Turbochargedtwelve]

Whoa, replacing whole connector pigtails or harnesses from one bad terminal? Can you not find the connector/terminal type, then simply depin the problem circuits, cut off the old terminal and crimp a replacement on?

[@gailtaylor1636]

@@Turbochargedtwelve A lot of these circuits are now using 22ga wiring. They are very difficult to achieve a solid connection especially if the harness can't be pulled up to get access to allow crimpers in. But this situation also brings up another consideration. Lots of instructors preach about not touching/moving anything around because it might temporarily "fix" the problem. I disagree with that. l still do wiggle/tap tests like Ford rec back 30 years ago.

[@Turbochargedtwelve]

Gail Taylor I haven’t seen that yet, but I work professionally on heavy automotive stuff (class 6,7,8) or personally on stiff no younger than five years old. Still, using 22ga wire only means that you need to find the correct size terminals and tooling for them. Every time you move a component you open yourself up to more liability and yes I agree packaging is super tight on most components. Getting the connector loose especially on high pin count ones like the major modules can be a real challenge and is often not as delicate as you’d prefer. Worst case scenario you do end up right where he did, needing to replace the whole harness, or at the least the whole pigtail. It is sad that policies now would rather get the vehicle back out the door quickly at the cost of expense and quality

[@carlthaysen5779]

Good reminder Mike. Tight is good. Thanks.

[@GoTechTraining]

Hey Carl, yes a tight fitting terminal connection is ideal! Mike Becker, Senior Instructor

[@markhonea2461]

I deal with many 5 vdc connectors similar to that in late model domestic refrigeration and MANY times have found an invisible micro-corrosion has occurred. It can throw off a 2-5 kilo ohm sensor to alter a compartments temperature wherever the sensor is in control . Slightly feeezing or not cold enough, and in certain environments, unshielded and unprotected connections will cause a 12vdc fan motor or baffle actuator to stall. It is uncommon for those components to be the problem, but if you do not test anything and blindly replace the part, the action of disconnecting and reconnecting that will certainly make it look as if was correctly diagnosed since the connection was refreshed from the reassembly act. I usually dry fu-xk the connector a half dozen times and tweak both members of that union, and maybe use electricians tape to create a barrier, and that will buy it a few or more years. Almost never happens on the line voltage connectors. And it's usually the N side of the DC circuit .

[@Anonymous-it5jw]

Great tips; you quickly narrowed down where the problem had to be, and you learned a lesson about checking the integrity of the actual connection instead of relying on back probing, which takes the actual problematic, low-socket-tension connection out of the tested circuit. If you had started by popping the white cover off of the sockets, you may have been able to spot the loose female connector by visual inspection before back probing that circuit and using new wires to go around the possible problem areas you had quickly identified. Thanks for making this video. I have a similar problem I am getting ready to dig into today, and the sharing of what you learned is extraordinarily helpful to me.

I currently have this U0101 code on my 2014 Chevy Malibu. When the TCM is down, the car is stuck in third gear (limp mode) and gear shift is not illuminated. When I drive 20-30 minutes in limp mode , the TCM does come back and stays as long as I keep driving. When I shut the engine off and wait about 10 minutes and turn engine back on, the TCM fails again, so it's an intermittent issue. Chevy dealership has no answers after I paid them 224 dollars in diagnostic fees. They wanted an additional $1300 to further diagnose it and obviously I declined that, so now I'm stuck with a TCM that goes in and out. Very frustrating.

GoTech Do you have any other good resources for networking that you recommend?

U said u were working on a wisconsin vehicle. Are u located in wisconsin. I am looking for some one that can trouble shoot the electrical. If not can u recommend some one. I prefer not to be the guy that just starts replacing things. I already have 1500 into it. Mechanic said we just have to start replacing parts. Had 2 different places lookk at it. Any help would be appreciated.

Great info as always Mike and always a pleasure even if I can't have your shirt, lol. Does the NGK email still work? Want to send you a little live data video for possible feed back. Everything seems wrong but no codes type thing.

Hey John, thanks for watching! I have new shirts, just need this stuff to end so I can go live and send them out :) Email me at [e-mail]. That's going to be the best way to get a hold of me. I'll take a look. Mike Becker, Senior Instructor
