How to repair automotive ECMs Class 2

HI all!
On this class I show how to get the pin outs for the ECM and how to connect the scanner to see the pids while the ECM is on the bench. A lot of good info here!

Great class i am all in for learning as much as possible and practice on old boards bad and good especially with curve tracing to build a data base this type of work is so fulfilling especially from an old school tech like myself who started in the late 80s when carbs were in and fuel injection was not out yet so i love it keep up the great work and God bless everyone

I work on the other side of repairs as a mechanic. I always wondered how intricate/complexed it is with ecu.. Now I know! Thanks Well Done..!!

[@MaicSalazarDiagnostics]

Thank you!!

[@davidshatusky8755]

Absolutely incredible material and the way you explain everything is amazing. I hope all the best for you. I can't believe I just came across your page. I rebuild diesel ECM's & FICM's etc.

[@MaicSalazarDiagnostics]

Thank you so much!

[@itsmekennyd]

I've started with computers in 1990 and went on to work in electrical for many years. I had heath issues and ended up doing automotive Diagnostics I have scopes and many other tools. I already use alldata. I started working on ecu and such due again to heath issues my meds I can't be out in heat alot so I changed back to board repair. Good job explaining to Know both sides really helps alot in this.

Highly specialized repair Maic. I didn't watch the whole video because hopefully I'll never need this skill. But for those who need this information you provided a very detailed video.

[@demonkliuchka8755]

You have done a really huge job to make this video understandable for everyone. It would be great if you probably give me an advise how properly resolve my issue??? I got Nissan X trail T 31 diesel, 4x4 , 2010 year. I got a problem with foult P1435. Its DPF. It happened because I forgot to clean up a cup oil catcher. ( My first Diesel car) I already done next steps. 1. Used AUTEL Launch scanner to delete all mistakes , but only one still remain on a dash board. Yellow Engine. 1.1Checks all sensors physically( oxigen, temperature, pressure) signal 5 volts comes to sensors. 1.1 Add DPF cleaner to a fuel and straight away before Catalytic filter and RPM between 2200- 2500 for 50 minutes to clean DPF filter. No black smoke. 1.2Car works well no power loss fast and powerful like Ferrari but unfortunately I can't ACTIVATE CRUISE CONTROL. CONCLUSION. I ENDED UP with conclusion that there is possibility that DPF filter is clean and This fault was gone to An emergency foulder. That's why Yellow Engine indicates on my dash board. To reset it from emergency Folder I need to visit a Nissan Dealer . I DON'T WANT TO DO IT. So MY QUESTION IS. Ktag programmer can help me to Reset this fault ??? Thank you very much for your Help. Sincerely yours, Dmytro Kliuchka

[@MaicSalazarDiagnostics]

Yes the problem is internal in DME, there is actually a TSB for it SI B 12 18 07

[@spinroyd]

Maic, heres a question. Do you know how the ECM decides to set a P0420 code. Is it the number of cross counts over .45 volts for the downstream 02 sensor? Have you ever tested an ecm to see what triggers this fault? There are a bunch of videos on P0420 but none discuss the actual cause of the fault.

[@MaicSalazarDiagnostics]

Well, it all depends on the vehicle manufacture criteria. I would look into monitor conditions for your specific application.

[@JK_Garage_]

Good video THANK YOU! ECU inputs testing LOOKS simple. How about outputs? In my country we have lot of diesel cars, with piezo injectors and outputs are fail in ecu. Also ECU wake-up signals if they communicate with can-bus how to turn on ecu?

[@MaicSalazarDiagnostics]

This is just the second class. All you ask here will be cover on later classes with more advanced level.

Hey brother I have a question that I don’t know where I’m going wrong with. I currently do DME BMW cloning with my Autel Im608. I currently just bought a Godiag GT100 breakout box since I want to get more in depth to be able to use my Autel Ultra or ISTA on the bench. I have a MEVD17.2P in my lab and for some reason with the godiag and ultra it is not reading DME. Not sure what I’m doing wrong but what would be the pin outs to get this to work on the bench? I have currently pin 1,22,40 12v, pin 1,3,11,7 GND, pin 43,44 Can L-H. What pins am I missing?

How would you find out the value of a burnt resistor on a board

[@MaicSalazarDiagnostics]

@@litemupkustomz the only way will be with a good board to save all the values for next time. Only manufactures ( BMW, Ford, etc) have access to internal schematics and they don’t give that to the public. Including me! It takes lots of hours saving information from a good board and reverse engineering the circuit board to find the correct parts, if possible!

[@sametyucelsarihan6477]

Hello Maic. We know that the Hall effect crank or cam sensor has 3 wires. When simulating an ecu powered by a Hall effect sensor, do you just connect the ground and signal wire between your simulator and the ecu?

[@MaicSalazarDiagnostics]

Just the signal wire. I usually have the ground and 5v ref or voltage ref wires set up with a 4mm banana adapter to make sure both are good and connect them to a multimeter to see the voltage.

Hello bro.... How are you doing.. I have watched your other videos on ecu repair from 1 t0 5 both on sensors,transistors(pnp,non etc) but I have a question on class 2 which I enjoyed but how is the connection between the ECU simulator, ECU and the scan tool. How are you able to use the scan tool to diagnose on the bench. I don't understand it and no explanation on it.... Do you have an email too or you prefer the KZbin comment section.... Anyway thanks alot. Better days ahead.

[@MaicSalazarDiagnostics]

Well connections from ECU to the simulator are based on each vehicle, powers, and grounds, the main signals, or the signal you need to test base on the customer complaint. The scanner connections are also based on each specific vehicle communication protocols, I use an OBD2 connector and supply the power, grounds, and communication lines from the ECM to DLC.
