If a control unit software detects a malfunction or a status fault, a Diagnostic Trouble Code (DTC) is registered. A DTC number consist of the control unit software abbreviation, suspect parameter number (SPN), and a failure mode indicator number (FMI). A DTC identifies which machine system is experiencing a certain type of problem.
