repairing dodge ram cummins engine computer (ecu) no crank, no communication

[@pootthatbak2578]

I did this work from 1981 till 1999..shiny metal balls on the semiconductors means a 98 percent chance it overheated, exceeded current, then you would find an internal open or short. Usually open. Smell that mosfet

found this video trying to figure out repairs to my ECM that had been soaked with oil from leaking injector wiring. wound up sending my ECM in to keyworks. very affordable repair pricing - mine was too roasted to repair (wasn't surprised, oil was dripping out of the plugs when i pulled it) but he hooked me up with a replacement for a good price. he was responsive and I got a quick turnaround. highly recommend.

Thank you for the feedback! Glad we could assist you with your ECM issue's!

Can you replace the zener diode with a tubular style one with the same ratings if the factory one fails or does it need to have more then two connection points? Thanks

[@ecurepair]

any proper spec tvs that fits would be fine

@@ecurepairreplaced diode checked for short circuit before closing up computer installed back in truck and keeps blowing fuses now I’ve got a short when bench testing may have to pull that mosfet to test?

If it over heated, I wonder if coolant splashed all over it. I looked up online of location of ecm on 2006 Dodge Ram Cummings. They say it's right side of engine comartment by the wheel well. So I guess it's possible.

Good work.

[@maradallibya5791]

Good job sir I work in laptop maintenance, and I often receive a car control unit, but I refuse it because I cannot find diagrams for it. My question to you is where can I find diagrams for the internal circuits, even just one diagram to train on?

[@ecurepair]

there are none available really. you have to make your own records and schematics for the internal circuits.

[@clems6989]

Very frustrating isnt it? You can slowly build your own library of info but you cannot find actual schematics. It takes a much better technician to work blind..

[@jv-man3698]

ECU repair seems like fairly niche and complicated work. What made you get into doing it?

[@ecurepair]

Just kind of happened from lack of affordable parts trying to get my customers going (I started out as a mobile auto locksmith & module flasher).

Im currently trying to diagnose a 04' ecm which after dead batteries was jump started and ran until leads removed and with charged batteries now has no communication, engine cranks, but doesnt start. When i supply power to the ecm on my table without ignition switch pin receiving power, i have 0Ma...ignition on i have .0027Ma. So maybe nothing is shorted?...Im not sure what particular areas to check. The obvious variables have been checked leading to ecm removal and investigation. Any help is appreciated and will donate for the guidance. I have a solder station, hot air rework system, transistor/mosfet tester so i am able to do the repair. Thanks!!!

[@ecurepair]

Its a pretty common issue I repair if you wanted to send it in.

[@morrispopov448]

@@ecurepair So its something you dont think I can repair or just a trade secret? haha Id like to execute the job myself but if theres no other option then ill ask the customer if hes willing to send it in. We just need price for repair and turn around time.

[@ecurepair]

Well you can give it a shot. I dont think I have any video 's on the issues your likely having. If you decide you wanted to send it in my info is keyworks.us/ramecu59.html

[@manuelamaya826]

Thanks.

I sent a message via your website contact form and haven’t heard anything back. I’m trying to get keys made for a VW beetle. When I try to pay, it’s telling me something wrong with verification code? Not sure what I’m doing wrong.

[@ecurepair]

sounds like your missing the google "I am not a robot" verification on the check out page. If your having trouble seeing it maybe try a different browser or you could also use ebay: ebay.us/MqnDK2

Merhaba profesör,cummins qsb 5.9 motor dtc 072 ECM iletişim hatası alıyorum bu konuda tecrübeniz nedir? Saygılarımla ☺️ x

[@garyjohnson801]

Where did you find that hold down for ECU. I can't find one like it

[@ecurepair]

Im not sure what you mean. I just have it open sitting on the table. The vice behind it, if you mean that, thats a panavise (Model: 334).
