EMCP4.1/EMCP4.2 Caterpillar

Table 1 lists the diagnostic trouble codes for the genset. The column titled "Display Text String" is the information that is displayed on the EMCP 4 control panel. To view the Suspect Parameter Number (SPN) and the Failure Mode Identifier (FMI), press the "OK" key while viewing the display text string.

If the diagnostic code was generated from the Electronic Control Module (ECM) for the engine, refer to the Systems Operation, Testing and Adjusting manual for the particular engine. Perform the diagnostic procedure as indicated by the SPN and FMI information.

If the diagnostic code is generated from the EMCP 4 ECM for the generator set, then refer to Table 1 and refer to the information that is in the "Troubleshooting Topic" column.
