I have a Ford Focus European 2000 with a 1.8 TDci engine.
I tried to build a PWM Interface to communicate with the ECU.
The interface is built around a ELM320 and I'm able to log the network traffic, but the ECU doesn't answer any of my requests.
My question is: I sthe ECU compliant to the ODB II standard?
Or is there a different protocol?
