How to repair car computer ECU. Connection error issue

[@EMJFUN]

I think you did an excellent job on this video. I did have to disconnect / reconnect the battery to reset.MY Transmission is now working without slipping when going from 2 to 3rd. THANK YOU

[@PeterFinnTheCarDoctor]

Great info and Thanks ! 👍

[@velocity800]

Marrie, did you solder the negative contacts too ? And then the car worked fine??

[@Ferreira019760]

I liked your observation of the board, it’s a very good tip to look at the grounding connections. Your English although not perfect is understandable, and you can get your thoughts across. If I may present a few ideas, try not to use your soldering iron tip on anything else than the solder, circuit board and component leads. It can get contaminated and prematurely worn, plus it can make your job harder. I always test the iron temperature with the solder itself, once it melts you are in the right ball park temperature wise. It should always be able to hold a small solder bead, if it doesn’t either it needs restoration or replacement. Using flux paste massively helps to melt the solder. The quicker it happens the less heat you will transfer to the board and adjacent components that might be heat sensitive. After soldering, a quick wipe with isopropanol will leave a clean and extremely professional look. I hope you take this as a contribution for other viewers that are getting started in electronic repair, aside from this thank you for sharing this video, it’s great to have people who help others improve their knowledge and skill. Most people get scared getting into circuitry as if it’s something massively difficult. As with everything else, there are some general principles to observe, proper techniques and the rest is practice as much as possible. What you did there helps demystify the black box that people see when they look at an ECU and don’t even dare cracking it open. Those usually just get replaced and they are very pricy, while it can just be a cracked joint or loose connection that any beginner can fix with limited knowledge and means. This is a good step forward, seeing how others have done it and following in their footsteps. Overall, you did a good job, I just wish you would have shown if that repair solved the problem. Well done.

Peter Finn the Car Doctor hello how are you doing Mr. Peter I have a 2008 Infiniti QX56 Jeep and one day the Jeep started malfunctioning the two side mirrors would open and closed every time the Jeep is started and the reverse cameras would come on when the Jeep is in drive and you please help me? The Jeep would not start so it got the starter rebuild and it is still not staring nah the computer is not reading the Jeep at all.

My mechanic just replaced my ECM . I bought it from "Flagstaff"(?) IN New York State $384 programmed and reconditioned. We already tried 2 from local junk yard. I don't know if it was required. I first replaced starter then ignition switch. I wasn't certain, but I'm more doubtful now with your video!

[@rogersy7209]

Ground and dc supply etch were thick and good absorb heat.. Therefore you need correct temperature and tip to melt solder lead.. Avoid lifting solder tip once solder lead start to melt . Let the melted solder lead to help spread more heat to surface. This is to avoid cold solder.

[@davidweum]

So far, I've spent $230/yr parts and labour over 13 years on my Saturn Ion 2.2 ecotec. I think that's a good deal for a free car with 130k miles on it. My brother told me that is a great deal all things considered to this point, but another BIG job may be a " bridge too far" and that I should consider a used Buick with a 3800 engine,$5000, 2000-2005, nothing fancy. That's the plan.

[@PeterFinnTheCarDoctor]

Ok.

[@24welly]

the solder is not burned out it is squashed due to the casing screws and is ok,it doesn't need soldering ,if you knew how to do it you would have put flux on the board,all you have done is to show how not to do it

[@DoshaYama]

It's very cool. if this video is watched by someone who does not have 220 volts grounded, then you attach 110 volts to your hand.😀😀😀

[@rickyshuptrine2831]

I liked your video, but it seems your Weller Soldering Iron has started running cooler than it should be. Taking the tip and the shaft off and cleaning them good at every connection with a fine scrubbing pad are a very light sand paper and cleaning and re-tinning the tip should bring it back like new. I've redone many old irons bringing them back to like new use.
