How to repair automotive computers class 1

Great video

Hi, what camera you use with AmScope SM-4TZ-144A ?

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

Thanks for the video, I'm studying to start repairing automotive modules here in Brazil. A big hug and thanks again for the information.

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.

super 👌 👌

I believe that black "thingie" is a combination mosfet to control the injectors. But don't quote me on that. I saw a video on one of those once. The author mentioned it is most likely to fail as it generates too much heat. But I can't recall exactly what the "thingie" does.

I have the same ecu, it do not function, can i have a number or e-mail please ?

I would like to learn how to do this specialized type of work. Thank you for posting these videos!

Thanks sir Maic for sharing your knowledge

Gotta love that $5000 fluke! So bad ass

Thanks ❤ may allah guide you

Simulate a Crank sensor hall effect engine revs!

What is the controller controlling?

That sucks when the Chilton diagram is wrong!!

Gotta learn locksmith too.

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?

loved it

Are very talented and polite to share you knowledge blessed ✨💖✨

thank you

Harry, we need you now more than ever.😢

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

What DVOM is that on the left side of your bench? Thanks! Subbed...🙂

Do you repair car computers? I have not be able get my 2010 Town Car Computer repaired? Would love to talk with you for help

Didn't know you had these videos in your arsenal

Do you repair bmw computers?

About your information to send you a jobs I like you to end my phone number and adress

modules rearly are worth repair. PCB is just to coplex if it is damaged due to moisture it is usualy not reperable, also ICs are hard process to remove and replace. That beeing said after you done time consuming error search. This job will most time be above the price of a donner module that can easily be found on the ebay.
It is another thing if car is old or rare and there is no spare parts. In this cases you can go reapir or replace the whole thing with programable racing ecu.

What a beautiful inspiration video, saludos desde New Zealand 🇳🇿

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

can I send you an ecu?

Very interesting. Pura Vida!

Any body know about gmc typhoon ECU's? I have one and the ecu failed 2 times. When it goes bad the ecu think the voltage is fluctuating and high but the actual voltage is fine.

Thankfully

You can't have point eleven. It's point one one. Eleven means a ten and a one.

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!

Great Video, direct subscribe👍

Thanks & good job. Cool bench setup.

hi maic I like your classes and am in the Bahamas and an auto tech and do need computer repairs so send me ways and mean that I can do business with you I have contact in the usa that I use to get my parts ordered but I need a reliable computer repair shop your help is greatly appreciated

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.

Saludo buenas tarde sir tendra alguna tutoria o curso en español

Man I'd love to just be able to adjust the fuel and ignition curves in the ECU of my late 80s Toyota 😂

Very interessting. All good for you.

Hi Maic, Great work. I have a quick question you may be able to help with, currently working on a telematics ecm & I have just realised there is a 120 ohm resistor in the ignition feed wire to the ecm. What could this be for ?

Question, so how do you get all the potting material off of the computer board. Most car CPU's are potted into metal or plastic boxes??

Aloha.............

Hello Great electronic repair video. Thanks. Where did you learn to repair ecu's.

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?
