hello everyone

I was wondering if anyone could confirm whether the ECU on that car is OBD-II compatible.
I have a cable built for ISO standard using Jeff's schematic with optocouplers and pins on the the OBD-II connector of the car seem to indicate ISO support. I know dealerships use MUT-II, but I thought that manufacturers are obliged to support common standard to some extent.

I would be very thankful for any advice. maybe I need to manipulate the ignition key somehow before starting the software? the software says that the adapter is detected but the ECU is not responding.

thanks very much in advance.
