Troubleshooting Procedures
Diagnostic codes can be viewed with the Display Module or Cat® Electronic Technician (Cat ET) Service Tool.The following procedures may cause new diagnostic codes to be logged. Therefore, before any procedures are performed, make a list of all the active diagnostic codes to determine the system problems. When each procedure is complete, clear the diagnostic codes that were caused by the procedure.Note: Before performing a procedure, always check all the circuit breakers. Repair the cause of any circuit breaker that has tripped.Event Identifier (EID)
An Event indicates a reading that is outside of normal operating ranges but within component limits. An example might be a high oil temperature reading. The event will be identified by the ECM, the EID, and a time stamp.Component Identifier (CID)
The Component Identifier is a four-digit number that represents a particular component on the machine. For example, each solenoid that is connected to the Machine ECM has an assigned CID. Failure Mode Identifier (FMI)
The codes for the Failure Mode Identifier are defined by SAE standards. The following list contains a Caterpillar version of definitions.
