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.
