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
Sir, you are a life saver. As manufacturers try to shut down the independent repair market and parts become discontinued. These skills are vital. Thank you for sharing your knowledge.
Thank you so much!!
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
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
@@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
Automotive diagnostics has lead me to circuit board repair too. Currently fixing my first ECM with a fried injector driver. Can't wait for part 2. Love the lab set up too.
where do you order the replacement to match the OEM output driver transistor??
@@glasser2819 Junk yard parts ECM. Some guys can better figure it out than me.
Thank you for sharing your knowledge and tips. I have been in electronics my entire adult life; from manufacturing to rework and repair. I am working on my first TCU and stumbled on your video. Stress level decreased by 200%!! SUBSCRIBED!
Llegue a este país ya viejo soy mecánico desde mi país México, pero encontrar personas como tú hombres buenos y generosos, con su tiempo y su conocimiento e infinita paciencia.
Los videos en español son muy apreciados por personas como yo con limitado inglés
Gracias y mire videos imagino que es agotador, pero altamente apreciado por personas como yo un video donde describes tu equipo y estoy tratando de acompletar el mio
Das precios y consejos eres increíble generoso gracias
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.
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.
I would like to do this course in india, how much does it cost?
What a beautiful inspiration video, saludos desde New Zealand 🇳🇿
Muchas gracias!! Saludos
Thanks for the video, I'm studying to start repairing automotive modules here in Brazil. A big hug and thanks again for the information.
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.
@@florenciomartinez3695 is it the “make: electronics by Charles platt” or a different book that you mean? I’m interested in purchasing
@@emyrhughes6582 Yes he has a series of books on electronics, but that particular book is the one i started with, I do the same type of work as Mr. Salazar, it is rewarding,
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.
Yes this is another level. i know people who do that kind of repair here in Serbia (sometimes it is to expensive to us to buy new PCM) and i do like to see that kind of repair on youtube.
Man I’m really impressed I was impressed before on all your previous video but I did not know you went that deep into repair of electronics.
Thank you! Hope these classes help others!
I have just started watching your ECM repair classes, Maic, I don't know how I missed watching them for so long as I have been a subscriber for a long time. Thank you for this brilliant information, much respect for your skills and knowledge.
PS. Don't worry to much about English as a second language, you are easily understandable and speak better English than many people who were born in the US lol. Thank you mate, love from Australia.
Thank you so much! Blessings
your intelligence is far more understandable than most people 😜
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.
ADPTraining thank you so much for the advice I will look into that!
ADPTraining by the way I am subscribed to your channel for long time. Great content and great tools
I am also subscribe to ADT channel really good channel
You're are doing a great job also i do my own circuit board ( modules) repair but i will learn a lot more from you.
So thanks
Subscribed! looking forward to learning more about the internal repair techniques.
This is so cool, Maic! Looking forward to the series :)
Pine Hollow Auto Diagnostics thank you so much my friend!!
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.
Thanks for sharing your knowledge with us. I’m looking forward to more of these videos.
This video im Looking for .. thanks for sharing this kind OF stuff .. im starting learning in your Channel .. I hope you Will continuing sharing this knowledge Bro thanks .. keep it UP
Great to hear!!.. I am from Costa Rica... Me encanta saber que aprendo de alguien de aquí.
Saludos y pura vida!!!
Buddy, this is soooo good. Also +1 for the Hakko gear. I love that solder sucker, worth every penny.
Thank You Maic! Very interesting and specialized videos on automotive repairs. Just discovered You and will definitely follow You.
Thank you!!
Thank you for this clear demonstration, i currently doing boilers PCB repair but looking to jump on ECM course.
Also, a thermal camera, like a FLIR that plugs into your phone, is a great tool for quick diagnosis.
True. FLIR is game changer for component level troubleshooting.
Sir how does a FLIR enable you to troubleshoot? Thanks.
same question@@flower2289
Love this. I watched the whole video. Going to follow the next videos to learn more. Thank you so much
You really are an intellectual in your field.
Thank you!! Blessings
Wanted to tank you for taking the time to give us knowledge and the ability to learn the unknown. Thanks for teaching us how the mysterious box ticks. Very much appreciated in advance and wish you much success
Kevin C thank you so much
Thanks for sharing your setup. You've showed great work and repairs can be done in a small space with the proper tools. Regards from Panama!
really enjoyed you first presentation and look forward the the next to one. Thank you
I would like to learn how to do this specialized type of work. Thank you for posting these videos!
Cool electronics. Maybe you could direct me to a sight where I can purchase wiring diagrams. Thanks
This is a great video; interesting, informative, and educational. I can’t wait for the next one. You are an exceptional talent. Thank you for sharing.
Andrew K thank you so much!!
Maic thank you for making this video! Computer internals are new to me. I’m trying to learn as much as I can. Thank you for sharing my friend!
Hope all is well.
All good here my friend. Blessings
I like the class, I learned something even though I'm repairing ECU's for years now. Keep it up.
Maic, looks like a very interesting series. Maybe you can put a link down below to some of the equipment that you are using. Maic the all data schematics is that the monthly subscription or a diyer subscription. I have the Mitchel Diyer subscription. One other item can you explain a little clearer some of the terms that you are using like Ne signal. Maybe you did I will watch it again possibly I missed it. Will definitely watch the series and the channel. I'm a retired aircraft mechanic but I am trying to learn every thing I can about todays autos and their electronic systems and how they function. Thanks for the series and sharing Artie ❤ I also follow a lot of the guys you probably interacted with on super Saturday in Philadelphia. Excellent group of technicians. 👍
Hi Arthur,
In class 1 I did cover a lot if different aspects of what is coming on the next classes. This was just an introduction, I will explain with detail as we go. Thank you so much for watching.
Muchas gracias por la clase amigo
Eres una excelente persona
Gracias por enseñar lo que sabes
12/4/22 inicie la clase
Thanks & good job. Cool bench setup.
Great video Maic, please keep up with this series, thanks
Jonathan Dean I’ll be posting one class a week.
Wow!!
Brilliant idea for subject matter.
Clear, concise & truly educational !!
Bravo!!
Kind regards
This has been a privilege to watch!!
Keep them coming in whatever format you think is best.
Thank you so much! Working on class 2 coming next week
Just wow you got the brains..unbelievable
loved it
Great start on this lesson. I'm looking forward to the next one. Thanks
I’ll be posting one every week. Stay tune
Maic, i am late watching the first video on this awesome subject and excellent teaching and can not thank you enough for this u are indeed a gentlemen and a selfish person by taking the time and effort to teach and explain how thing been done Bravo Bravo and hope more people will realizes how important this is to learn and come to sign up in ur channel you deserve much more my friend . cheeeeeeeers ps: now to the second one and hope will be third one too to watch.
j georges thank you so much! Comments like yours encourage me to keep going with these classes! I am so happy be able to help others!
Nice comment j georges but I don't know if you realized that you just insulted him by saying selfish. The correct word is selfless. Just saying, please don't be offended.
@@dirktwojr thanks for correcting me on this really appreciated and happy new year brother.
Excelente. Y gracias. Por compartir
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.
RC Hobbyist Extreme great comment, that is true a lot of times is diodes or bad caps. Getting the data sheet for the components and learning how they work is key!! Blessings
I always wondered how it's done. Thanks for sharing your knowledge Maic.
Thank you my friend!
High level teaching style Sir ,...Best of Luck for success to be there with you in every walk of life...
Keep up the good work. thanks
This is awesome. Thank you definitely Looking forward to more.
You angel for me as I was searching a trainer to train ECUs repairing !
Are very talented and polite to share you knowledge blessed ✨💖✨
Thank you so much! Blessings
Maic Salazar:
Gracias por su tiempo pero lo mejor por GENEROSIDAD
Fantastic video mate. Very informative and much to be learned 👍
I was just able to finally finish watching this! Great video! And thanks for sharing! It was full of information for me!
Voltage Drop Diagnostics tha m you so much PJ. Class 2 is in the works and with even more great info.
Very helpful. Thanks for sharing
Didn't know you had these videos in your arsenal
Hola Maestro Salazar, desde la Florida, mil Gracias
Nice work! Not much detailed info out there on this stuff.
I was wondering if you had to remove each component to test it, like resistors and capacitors, but I guess not. Is that always the case?
Hello Great electronic repair video. Thanks. Where did you learn to repair ecu's.
Too the beginners out there. You don’t need to buy crazy expensive tools. You can get wave generators and such really cheap from China or if your electronically inclined it’s Easy to make a wave generator.maic is a professional so of course he’s got the nice tools lol. Great channel ty got your knowledge.
This is fantastic! I can’t wait to learn more. Thanks for doing this!
Hi Maic , your videos are amazing. by the way I was looking for workbench purposes how to bypass key inmovilizer , could you suggest a link or some information . thanks for your support
HELLO MAIC! Am an avid Subscriber, you are my first 'Go to' when diagnosing PC issues! I recently built a new Computer in my old Tower with a new Raidmax Vampire 1000W 80 Plus Gold Power Supply, an MSI Z390-A PRO Motherboard with an Intel Pentium Gold Processor G5400 CPU @ 3.7GHz! Next added 64.0 GB DDR4 3200 Ram! Also a ZOTAC GAMING GeForce GTX 1 Video Card! Recently upgraded all my HHD's with an Intel 660p Series M.2 1 TB SSD Drive C and two WD I TB internal SSD's! My Computer now boots up completely for a cold start in 30 seconds!!!! (Once in a while when I turn it on, it Boots into the Bios Screen)!!!(But when I wont to boot into Bios, no matter what key combination I press it wont go into Bios on Command)! Windows will not display on my Digital Monitor but I can see the Bios Screen on another HDMI Output to my 32 inch TV! Am running XMP Mode and Gaming Mode on the MSI along with allocating 3/4 of my Ram to Process my Adobe Premiere 2022! My Question is: How do I get the computer to Boot into Windows EVERY TIME? And secondly, How do I get my computer to boot into Bios on command?
Gracias, practico mi ingles y aprendo mucho con sus videos
I have repaired a few of these computer in my life but it's hard when you don't have Schematics, especially when you don't know where the power and signal inputs are to the computer. What sites do you get the those diagram from? I would really like to reverse engineer it like you do. Your skill are awesome and you are truly a master of this type or work. Thanks you for sharing.
Thank you so much. I use most of the time Identifix and Alldata. They are website-based information sites where you can pay a monthly subscription or in Alldata, you can purchase a specific vehicle and that will give you access to all the info for a year.
@@MaicSalazarDiagnostics Thank you.
Very interesting. Pura Vida!
Nice! Maic you're taking us into the deep lol if I'm honest I'm only watching for entertainment purpose. I have so much ground to cover when it comes to automotive diag that it'll take me two lifetimes to get into electronics. But definitely enjoying the process
I am very excited to see any videos on this subject you wanna make. I have been rebuilding GM Instrument clusters and prior to that was doing some TV repair. I have fixed a lot of other things with guides from online. I am just a part changer. I never figured out how to break down a board to component level. I understand electricity but I dont understand electronics on the level you do.
First, thanks so much for your kind comment. And yes, there’s a lot of good guide videos online on how to replace a part, but very view that show how to test if the part on the board is actually bad. I always wanted to share the process for how I determine if you have a bad resister, capacitor, diode, etc, since there is really no one else who does that. So hopefully, more and more people will subscribe to the channel and these classes will help a lot of people.
@@MaicSalazarDiagnostics See the thing is I understand I know just enough to be dangerous. Iv fixed probably hundreds of thousands of dollars worth of cars as well as consumer electronics due to the all mighty google. Im a hands on lets tear it apart type of guy. I just never had a mentor to learn the basics of electronics from.
Awesome Skill set bro.!!!
This was a great video. Looking forward to get stuck into part 2
Thomas Meany Class 2 is up already. Look for playlist
You have an impressive electronics repair setup.
Hello Maic, I have been folowing your tutorials on the use of the MST 9000+. I am looking into getting one myself, but before I order one could you please answer a few questions for me. What operating system do I need on my computer (Windows XP, Windows 7 ECT.) is thier a technical support team and a database for other ECU's not loaded into the MST9000+ Thank you in advance Mark.
You can use it on any windows. And no there is no support
Thanks for Sharing, it is too much for me ,but I am just with out Words. blessing to you.
Blessings to you too!
Useful. Thank you for sharing this information.
Sr. Maic feliz ano nuevooooo... hace tiempo que no comento pero estoy al tanto de los videos y aprendiendo aunque con dolores de cabeza pero ahi vamos!!.,...
You said ,,, on facebook post some videos,, please let me know you facebook page,,, thanks,,,
and keep going,,, never stop growing as a person ,,,,
Que la vida le siga bendiciendo....
Muchas gracias mi estimado Gerardo. La página en Facebook tiene el mismo nombre o me puede buscar como Maic Salazar Garro. Muchas bendiciones
Thank you for your time and enthusiasm. Great explanation.
Thank you!!
great video amazing well done
What the software you use to get the wiring diagram for ECU, can you give link to the software please?
Cool informative video
I love learning ECU repair and i think i got what im looking for from long time
Thank you Maic
This series will be fun to follow along. Anticipating more use in the next few years, I've been slowly growing my skill and tool set. Fortunately the cost of some tools, like the microscope, has fallen dramatically. Basic principles apply everywhere, though programming will always be a stumbling block. Few will be able to afford your engine computer simulator, ha ha. Also I'm a little concerned that SMD manufacturing methods will make some future repairs impractical. The last phone I -worked on- played with had resistors and capacitors as small as a grain of dust. Even so, it's going to be an entertaining ride!
Pura Vida bro!.. Soy de El Salvador de nacimiento y tico de crianza... Saludos!
What do you recommend to study for reaching up that knowledge in electronics, from scratch up. Peace!
Tus videos en inglés son muy buenos, tu inglés es maravilloso menté claro
I came here to try and diagnose an ecm, now I'm leaving here knowing I'm to dumb to repair an ecm and should leave it to somebody else
Hay Maic, I am not an auto teshnician, but i do practice electronics as a hobby, so i am thinking that i may be able to suppliment my incom by getting involded in this kind of work, I am so glad that you are sharing. Do you keep, and or do you shear your Casehistory of the components that you had to replace on different make and models of bords? My name is Clifford and I live in Trinidad and Tobago.
This is a board from 30 years ago, modern boards are many many times more difficult.
Hola Maic, que bueno que encontre tu canal. Me quiero meter en este mundo de los modulos automotrices. Voy a disfrutar muchos tus videos. Saludos desde Barrio San Jose de Alajuela, Liga liga campeon!! lol
Bendiciones! Pura vida! Viva la LIGA!!!
Love this Maic, can't wait for part 2😁
Flat Rate Master thank you so much my good friend
Good info. Thanks.
Thanks I am from South Africa and need to know more to do practical solutions in South Africa Thank U a lot
just joined i learned more in 10 minutes than the hours spent online. have to ask what is the investment in equipment?
It all depends on what do you want or will be repairing. Multimeter, oscilloscope, microscope, soldering station, hot air station, de-soldering gun, signal generator. To start
Hola Maic, una pregunta respecto al osciloscopio Siglent y el Fluke Scope, es necesario tenerlos a ambos en el laboratorio? Cumplen funciones similares o con el osciloscopio Siglent y un multimetro digital regular se pueden llevar acabo los trabajos?
Claro el siglent es muy bueno y con el multimetro es suficiente. Además te recomendaría que uses este de 5.5 digitos para cuando quieras encontrar un corto a masa,

Good morning Maic ! Thankyou for posting these ! I have a PCM from my 2009 Mazda tribute with some corrosion damage. There is only one component with visible damage but I don't know what it is, resistor or capacitor? One leg is completely corroded away so I can't connect a meter to it. If I send you a couple of pictures and the numbers from the unit I wonder if you could identify it for me ?
the numbers on the component look like "842 U1J", there is also a circle with " (ON) "
any help would be appreciated !
ps: I bought a " plug and play" replacement from "flagship1" but it wasn't , and obviously has never been opened up for any refurbishing.
best regards !
Jim
Keep up the good work, I am in. 🚘🔧💻📉📈 ✔️ 💪
Hi Maic. Is it possible to diagnose the transmission computer system on BMW 745 i?
Savia que eres muy bueno pa la mecanica.
Pero ya esto es otro nivel mano...
Uffff.Respetos.....
Ahhhh,Nice collection of toys.
Envidia de la buena 😁😁😁😁..
Muchas gracias!!
Great video, I love your lab setup alone :)
I have improve a lot more. Please check my latest videos. Thank you so much!
nice.. keep sharing
very informative videos for those people who interest in repair the ECUs...
Man this makes me save all my modules and see if i can fix them. Thanks for the class
