Whatever car you are working on you can get a 1 month access to Alldata-diy, or 1 day access to OEM wiring diagrams for a few dollars. It really pays to use those resources.

[@Bosbulls]

@@mrfrenzy. can you please send me a link for this. I actually needed a wiring diagram for my personal car the other day to trouble shoot a intermittent shutdown. Eventually I found the problem by accident as there were a broken wire that made contact, but sometimes would loose that.

[@mrfrenzy.]

@@Bosbulls well it depends what country you're in and what brand car you have, if you have a car that exists on the American market just search for "alldata-diy". If you have a small European car you need to find the manufacturers website where they sell diagnostic info (which they are required to both by EU and USA laws). Some brands require that you have a company to get access but the price is usually reasonable.

[@thelostshadowofhanzo]

Well done on an other great repair. Exactly, using common sense and the wiring diagram you were able to find the fault. I have often used this exact method, start at one end of the circuit, normally the easiest to access part first and work your way along. This has served me well countless times. One thing I would like to point out is, that corrosion in the wire has been there for a while. There is a possibility that it was the cause of the original fault, or if the control module was faulty it may have been the cause. There would have been high resistance in that power feed to the module, and with the fact it completely failed the next day after getting a new TCM, I would bet it was more then likely the cause of the transmission shift problems. I would bet the circuit was having intermittent opens as the wires were only just making contact. It definitely looks like the previous person who tried to diagnose that lost their head!😄 stuff pulled out and disassembled that did not need to be. It is amazing how so many people on this industry can not diagnose electrical, I mean a broken wire is pritty simple. It is sad that the guys like me who are good at this don't get appreciated for that fact we can do what many in this industry cannot. Keep up the great videos Dan, I always enjoy following along and trying to think of the next step before to show it in the video.

[@Diagnosedan]

These easytronic modules fail alot. The unit was send to ACtronics and they comfirmed the unit was faulty and repaired it.

[@thelostshadowofhanzo]

@@Diagnosedan then I still think that wire may have contributed to the module failing. Either it was broken and touching slightly on and off causing voltage spikes. Or the excessive resistance and low voltage caused the TCM to fail.

[@pcdispatch]

This makes sense. I do not believe in coincidence when work was done shortly before. I am a software engineer and sometimes after a software update some other problem arrises. More than often the other problem has some (unexpected) relation with the work done before. I like this channel and always wondered why a garage cannot do proper diagnosis. Without analytical thinking and diagnosing I cannot do my work.

Nice job!! In some cases, a broken wire can be very hard to find, especially when the wire in question looks okay, when it is not, because not all wire breaks result in the wire breaking completely. These cases are when the wire breaks without breaking the insulation.

[@Conservator.]

Let alone intermittent faults. 😁

[@Diagnosedan]

Thanks Christopher!

[@christophermarshall5765]

@@Conservator. those are just as bad!

[@khalidacosta7133]

In those cases, I just tend to replace the entire wire as best I can. Normally most wires can be fed through existing grommets etc. Yes it is a bit of a bodge but use high quality wiring, route it in a way that a mechanic taking apart something else won't break it and it'll last the life of a car. It's usually not economically viable to remove the entire loom to check!

This video, as well as the one pinned, shows that this model of car has factory issues in that area. I'd bet that there's too much tension on the wiring harness that causes the wires to break over time. I mean, in both cases, the wires that broke were a clean break. Almost like they were cut. This is good to know and just might assist when troubleshooting any other vehicles. Job well done!
