Enter Engine control module.
Module information. Hardware and software.

Write coding, backup, recover. Very nice.

Enter “EOBD”, we can only connect to the engine control unit.
“Match” CANBUS protocol, we can see VIN code and DTCs.

Live data.
Accelerator Pedal, Catalyst Temperature, Fuel Pressure, Ignition System, Long Term Fuel Trim, oxygen sensors…

Nice, too. But just Audi, Mercedes, Toyota.
