What Does FMI Mean? (Can be changed)
FMI refers to Failure Mode Identifier.
Diagnostic fault codes reveal particular problems within a component or system circuit.
For instance, FMI 4 might be triggered by MID 116-CID 854, indicating “Voltage below normal.”
At Clue, you'll often encounter FMIs like 3, which means “Voltage above normal,” and 9, referring to an “Abnormal update rate,” among the many fault codes we handle.

MID refers to Module Identifier.
Caterpillar’s latest machines feature advanced Electronic Controls that can accurately identify specific modules, components, and types of failures.
For instance, the MID code designates the particular electronic control module responsible for detecting the fault, such as MID 116 for Integrated Brake Control.
