Thank you for this video! Was putting my truck back together and the positive battery cable touched the ECM housing. Then I had no crank/no start. Opened up the ECM & sure enough the ground pins were broken within the connector. Remains to be seen if it’ll still work in my truck. I’ve replaced the most rear pin, the two easier ones tomorrow.

Good tips, but Would you be kind and say what software did you use to made the back up?? Merci monsieur

Hello, can you tell me why this ECU, after repair, does not work in the car? Many repairers here suffer from this problem. I am Brazilian. Thanks

what temperature are you using for the solder pin at 14:00 ?

[@autodiagobd]

It’s all about heat transfer. If the factory solder of those pins melts at 300 celsius degrees and the traces or the pins are big, you need a powerful soldering iron that can keep up with heat transfer. Or you need a preheating station to rich the temperature near melting and just a normal soldering iron.

I had to raise my solder temp to 375° C to reliably melt the existing solder, even after mixing in leaded solder
