The DTC (Diagnostic Trouble Code) consisting of SPN (Suspect Parameter Number) and FMI (Failure Mode Identifier) delivers specific information about a faulty property of the Diesel Engine.
The SPN indicates which property is in a faulty state. The FMI provides additional information about the type of error, for example, a short circuit on a sensor.
