Mack Fault Codes. TROUBLESHOOTING
MACK FAULT CODE IDENTIFICATION TABLE
Definitions
MID (Message Identification Description):
Identification of ECU
- The MID identifies which ECU is broadcasting the code.
- Example: MID 128 indicates that the code is being broadcasted by the Engine Management System (EMS) Module.
SID (Subsystem Identification Description):
Identification of component
- The SID describes the fault code.
- Example: SID 1 represents a failure with the Fuel Injector Unit #1.
FMI (Failure Mode Identifier): Identification of
parameter value
- The FMI specifically defines the fault.
- Example: FMI 7 indicates that the mechanical system is not responding or may be out of adjustment.
