TEE 1925425 - Caterpillar

The Electronic Control Module (ECM) has the ability to diagnose many different fault conditions that are associated with the electronic components that are found on the engine. Each electronic component is represented by a Component Identifier (CID). Each diagnostic fault condition is represented by a Failure Mode Identifier (FMI). The two identifiers are combined in order to form a CID-FMI description. This description is called a diagnostic code. When a problem occurs within the engine electronics, the diagnostic code is used to pass diagnostic information to the operator. For more information, refer to the Electronic Troubleshooting Guide for this engine.As a diagnostic fault condition occurs, the ECM sends the CID-FMI to the Generator Set Control+ (GSC+). The GSC+ communicates the diagnostic information to the operator. All of the possible diagnostic fault codes for this engine and the fault code descriptions are listed below:
