Diagnostic Codes

The Society of Automotive Engineers (SAE) and the Maintenance Council of the American Trucking Association (TMC) have developed a standard data interchange format referred to as J1587. This format defines a standard data list, controller names and numbers, parameter names and numbers and diagnostic fault code formats and numbers.‪

Parameter IDentifiers (PID) are numbers and names used to identify the data in the message (i.e. engine RPM, coolant temperature).‪

Failure Mode Identifiers (FMI) describes the type of failure detected in the subsystem or part identified by the PID.‪
