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.
Flash Code provides a two digit number to advise the operator of the general severity of the fault.
