Definition. Identification of the fault code. Make-up of a fault code: A fault code is made up of:
- a “MID” code associated with a digital value to identify the ECU,
- a “PID” or “PPID” or “SID” or “PSID” code associated with a digital value to identify the origin,
- an “FMI” code associated with a digital value to identify the type of fault.
