This is a very specialized area of repair. Totally necessary with modern vehicles. I'm glad there are techs such as yourself that tackle these jobs

[@keithnoneya]

I did this type of reverse engineering work on aircraft test sets when the manufacture no longer supported the end item. I too would make up test fixtures to test single boards or the whole unit. This type of work is very specialized and time consuming but when it's done you have a good feeling and a great amount of data to use in the future. I had a lot of fun doing that type of work and made ok money doing it. One of my specialties was repairing heavily damaged circuit boards. Boards that had missing runs, burnt runs or were burnt all the way through so that all that was left was a sheet of charcoal in the damaged area. As long as you have a schematic or the board still has the charred runs on it you can repair it. The hard part was inlaying new PCB in the charred out area after it was removed and adding the new runs and Eyelets. Thanks for sharing, I look fwd to the rest of the series. Best Wishes & Blessings. Keith Noneya

[@roseelectronics4582]

It's common to find through-hole burns in boards and they can be repaired but it's a nightmare when it comes to multilayer boards

[@keithnoneya]

@@roseelectronics4582 Most definitely, multi-layer is not a lot of fun to repair when you have to go through several layer. Usually I just run a jumper wire on top of the board if it's buried to deep or not work the effort. Best Wishes & Blessings. Keith Noneya

Hi Maic I joined Hi-tech Automotive Training Academy in Panjab, India. They have a two month, immersive, component level ECM repair training program. I'm watching your videos as a supplement for my training. Yours is a great channel. Keep it going.

This is really awesome, Maic. Thank you so much for taking the time to put this together. Very much looking forward to following this series.

You have some nice equipment. I have that exact X-Tronics soldering station and it has never failed. After I purchased it I actually got a email reply from X-Tronics after I asked them about replacement parts, and they said the 4000 series was their most trouble free soldering station they sell. They claimed it would be rare it would ever need any parts on normal wear if it hasn't been abused. I've had it for about 4 or 5 years now and never even had to replace a heating element in it yet... and I've used it a lot. Never replaced a tip, as I use tip tinner, and that stuff works. Your recommendation is right, this is a good unit.

Man I am learning a lot. I am pretty much self taught in using a lab scope for my diagnosis and picked up a few books. I was always curious to learn how to fix the electronics. I live in a very low income area where people can’t afford high dollar repair on electronics and I try my best to see what I can do save them some cash. I’ll be watching more videos man great stuff!

Try Platt Making Electronics great book pretty much all that us techs need to start learning basics and then grow from there you will be surprised what you can repair just learning the entry level electronics a circuit board from a ecu is no diffrent than a lg tv ccircuit board just does different tasks and keep at it if you learn the CAT diesel ecu repairs jeez the amount of money you will save your customer.

There are limitations and always will be with ecus. Modern ones have multi layer boards and troubleshooting them usually reaches a cul-de-sac. We had a lot of success with the 80s and 90s ecus with resistor, transistor or cap faults. Mostly caps become faulty, leak or swell and are easy to spot.

Just knowing what is negative and positive before replacing bad capacitors is really important. Placing a sticker on the computer doesn't mean you know what you are doing. I had to fix the computer in my own vehicle because some numbnut that replaced a cap reversed the polarity. Once you figure out what does what, its not that hard to figure them out. Faults normally starts with old capacitors and other voltage regulating components. Knowing how to read values and looking up the factory values on components helps alot. The parts that normally fail are the actual solenoids, injectors, coils, etc. Sensors and anything under the hood will fail before the components in the ECM.

[@MaicSalazarDiagnostics]

It's amazing seeing a tech delve so deep into electronics like you. I actually design and manufacture my own Auto diagnostics equipment and you're looking good. On another note, you can do more that that Chinese tool you have by using an Arduino MEGA2560 board. The issue us that the Arduino can be made to respond like an engine, that way you can see ECM response. Like for example, an ECM that kills inj pulse during an issue.
