damaged EECU looks the other way, i'll post you pics this evening

this is ECU used now with D13. Try to get it powered and check pulses on J1708 and J1939 pins. Check for 5V internal power supply

as detachment plate to see the other side?

You'll destroy ECM finally.
Belive me CAN Trancievers are ok, something is wrong with internal power supply cirvuits.
ECM is short inside. let me be home to post pics
