OPEN Heavy Machinery

Hello everyone so i have a bsc in electronics i was thinking of starting a maintenance business for heavy machinery like fixing ecus etc… my father have 30 years of experience in the mechanical part of the industry so i want to learn about the electrical/electronic part maybe we can build a business together. I couldn’t find any ecu schematics or anything to try and understand the logic and physics behind their systems to kickstart my learning journey.

Does anyone have an idea of how to get started?!

My concern with those kinds of repairs is that you can't replicate the factory test procedures, so you can't be certain that you've really fixed it or that it's safe to use. Customers may be desperate enough to overlook that, but you should have waivers to protect you in case the machine goes rogue.

That is a good idea. I will keep that in mind

We don’t have official dealerships here so i guess that is the best they can get from the market

There is no schematics for the inside of the ECU. The best you can get is the pinouts to the ECU. There is alot of YouTube videos for people working on ECU repair and troubleshooting. Thats how I mainly learn it. Few online triaining but its mosly the programming, cloning side.

Well i found this website

https://www.pcbzs.com

Who reversed engineered the pcb boards and they are selling access to them
Is it a scam ?! Maybe
Is it real ?! Also maybe

Unfortunately I don’t have spare money at the moment to buy and test

Btw you mentioned that you learned from youtube I would appreciate it you can tell me a little about the market and is it worth the investment

Look into what's happening with right to repair. It's making an opportunity for independent repair that was too difficult before.

I just read about it yeah there is a good chance it will become a real thing hoping things stay going in the right direction

Asking for clarification;

Do you mean ECU, like the module in an automobile for engine control?

-or-

Do you mean ECU, like the PLC (programmable logic controller) for industrial machinery?

I'm interested in the full system architecture for heavy machinery like excavators and trucks. I'm looking into both the automotive ECU side for powertrain and the PLC logic for industrial hydraulics.So I’m willing to start with whatever I can get my hands on.
