[Pages:394]SS 1033423 : J-1939 Fault Code Source Address (SA), Suspect Parameter Number (SPN), and Failure Mode Indicator (FMI) Descriptions

J-1939 Fault Code Source Address (SA), Suspect Parameter Number (SPN), and Failure Mode Indicator (FMI) Descriptions

This solution helps explain the underlying meaning of the numerical components which build a fault code.

- This is not a comprehensive list, or an alternative to the standard fault diagnostic process and only serves as a supplemental reference - For a complete reference see SAE documentation regarding Serial Control and Communications Heavy Duty Vehicle Network -

Applicable Vehicles Any - This solution is intended as supplemental reference information to be used in a general context to assist in troubleshooting.

Where Used When Fault Code Descriptions do not provide the level of detail needed to diagnose an issue i.e. "too vague". This may also be useful in cases where multiple codes have identical fault descriptions.

How to Use For example using slash notation (SA/SPN/FMI)

Fault: 11/1049/3 - Pressure Sensor 1 / Analog input 1 SA - 11 = Brakes - System Controller (ABS) SPN - 1049 = Brake Pressure Sensing Axle 1 FMI - 3 = Voltage above normal, or shorted to high source

In this instance breaking down the code may help explain what's happening behind the scenes and identify the problem.
