Hi, i just found that marea 1.4 12V uses KWP71 protocol.
I was succesfull reading some codes using Unidiag KWP71.
Just need to understand the protocol now though, to implement the code in an AVR Microcontroller....

Thank you.

Hi,

Do anyone knows the protocol used by the Bosch Motronic MA1.7.3 ECU?
I'm developing a ECU scanner for a university project on a Fiat Marea 1.4 12V and i'm not being succesfull so far.

Thank you in advance
