Okay a couple of things before we proceed. Make, model, year of vehicle and engine size to start with. if you have a part number for the ECM, that would be helpful and perhaps the manufacturer of the ECM. Delphi, Toyota ????
Next, can you show pictures of what it is you did to get you to this point? I am assuming you tried to replace incandescent lights with LED's and therefore changed current and resistance levels in the circuit you are ow trying to repair. LED's work at very low voltage and current in comparison to incandescent lights, just for future reference.
Lastly, the pictures you have on here are not comprehensible. Try to get a good clear picture from above of the entire board, and then in close on the section that is damaged. Then we can help you.
