i'm a newby on your forum, and i saw that there are a lot of people friendly with OBDII and Car Buses.
I want to program, via an Arduino, and interface, a steering ECU(TRW) from a Renault CLIO II
it seems to be driven by ISO 9141-2 (Kind of 12V Asynchronous Serial protocol).
But i have never done that before,
maybe one of you knows how to start ?
what to put as header for communication ?
What are the PID for functions ?
Is there any possibility to ask to the ECU to list all the functions he have ?
If i get the Eeprom Hex, could we do something with that ?
Please, i look around on the internet all the day without finding something reliable.
Please let me know
