Hi. I hawe car Megane III 2013 with ECU EDC17C42 1.6. Car don't start, won't communicate with ecu.
Other used ecu - communicate OK. Im read wia BDM (Ktag) - im think file OK.
Betwen can lines 120 ohm, possible damage IC 40076 Bosch?
I marked where the can lines are coming from.

what about voltage on network H & L ?
CAN H /GND - 3,12v
CAN L /GND - 1,82v
CAN H/CAN L - 1,28v
I think OK, but meybe im wrong.
