    Greetings, I am a newbie.

    I need advice on what appears to be burn marks on an Opel Astra G 1.6 16v C16SEL ECU that did not output a 5v reference voltage and 12v supply to crank sensor. Having checked all fuses, I set my eyes on the ECU and removed it...

    Attached are the videos... please confirm that I am seeing the right thing.

    Much thanks

    Based on these photos, it's hard to tell if something burned there. Take a good magnifying glass and tweezers, check all the hairs that go to the main knuckles. They often burn out or break. And in general, this ECU is very cheap, only the issue of immo will remain. I made several such hybrids. And in each of them a few hairs had to be replaced

    Thanks buddy.

    Let me upload another video. It looks like something has burnt when I check under a magnifying glass.

    Buy a second controller if you think it's his fault, they're priceless. You don't even need to spend time diagnosing the fault.

    That I will do. But I would like to confirm whether those are burn spots or not.

    I am not good with electronics, but I am a mechanic.

    Have you tested this 5V line to see if there is a short circuit? I often test by disconnecting the 5V lines from the controller and supplying external 5V from a battery power supply with a multimeter connected to measure the current consumed. Motor controllers have current limiters on the 5V line power supply. If something draws too much current, the entire power line goes down.

    @sigwa18 I did that, my guy. I will buy another ECU as I am now confident that those are burn marks. Thanks, everyone. I appreciate the help.
