Hi Dave, really sorry to hear of your problem. I'm with Richard I find it hard to believe that MMC have locked out basic OBD2 access. As I understand it OBD2 compliance was made a legal requirement in America for all new cars sold from 1996 and Europe followed suit in 2000.

My car is a 4/4 with a Ford 1.8 silver top Zetec. The car left the factory in November of 1999 and was fitted with an ECU that is not OBD2 compliant it doesn't even have a MIL light fitted. It just scraped in legally for this country by a couple of months. It could not have been legally exported to America at that time with that ECU fitted. It took me a very long time to find software and hardware that would connect to this car. I eventually did and it turned out to be Ford DCL protocol. By 2016 that should have been long gone.

I can't help but wonder whether the inability to connect problem, is in fact a wiring fault. I am sure Richard would be able to check if cables from the diagnostic connector share a common multipole connector with the MIL light somewhere on rout to the ECU. It may be the ECU connector itself needs reseating or even (most unlikely) the ECU is faulty. Even if MMC locked out OBD2 access there would be no point in disabling the MIL light and given your severe symptoms that should defiantly be illuminated.

The photo bellow shows the standard pin out for the OBD2 connector. The lower diagram is for your car, note the diagram does not mention that pin 16 is at battery + volts with ignition on or off. You can ignore the upper diagram that is for my car and ignore my scribblings.


Regards Tony
