Decode Your FMI:MID:CID Fault Code Now
What Does FMI Mean?
FMI refers to Failure Mode Identifier.
Fault codes are used to diagnose specific issues within a system circuit or component.
For instance, MID 116-CID 854 could trigger FMI 4, indicating "Voltage below normal."
At Clue, we frequently encounter FMIs such as 3, which means "Voltage above normal," and 9, signifying an "Abnormal update rate."
What Does MID Mean?
MID refers to Module Identifier.
Caterpillar's latest machines are equipped with advanced electronic controls that enhance the ability to diagnose issues by identifying specific modules, components, and failure modes.
For example, the MID code, such as MID 116 for Integrated Brake Control, indicates the exact electronic control module that detected a fault.
This system allows for precise troubleshooting and quick identification of issues, helping to streamline maintenance and repairs.
What Does CID Mean?
CID stands for Component Identifier.
The CID helps pinpoint a specific circuit or system, usually within the MID.
For example, CID 854 - Brake Oil Temperature Sensor (Right Rear) is related to MID 116.
At Clue, our top three CID fault codes are 3565 (Air Conditioner Suction Pressure Sensor), 1961 (Hydraulic Oil Temperature Sensor), and 1469 (SAE J1939 Data Link).
