Reading DTCs from any ECU on CAN

Postby frankarnecke » Tue Jan 29, 2019 4:08 am

Hello,

I want to read DTCs from any ECU on the CAN. I know the address and whether the ecu is working with KWP on CAN (ISO 15765-2) or UDS (ISO 15765-3).
Basically, it should not be that difficult, but I do not know where to start and if it even works with the Freematics UNO. Is there any similar application or a library existing for that?
