The CID and the FMI are displayed together immediately after the MID is displayed. The CID and the FMI replace the MID. The CID describes the component or the subsystem that generated a diagnostic code.Failure Mode Identifier (FMI) - The FMI is displayed on the last three digits of the six digit display. The FMI begins with the letter "F" and the FMI ends with the two digit failure mode identifier. The CID and the FMI are displayed together immediately after the MID is displayed. The CID and the FMI replace the MID. The FMI describes the type of diagnostic code that has been generated.TATTLETALE MODETattletale mode is a tool that is used for management and maintenance. Tattletale mode is used in order to track the engine history. The main display module records the extreme value for each engine condition that is monitored. The values come from the sensor inputs and from the engine ECM through the CAT data link. The tattletale values are updated when an extreme value occurs. The previously recorded value is replaced by the more extreme value. These values are ignored for a short period of time after each engine start-up. This allows the engine systems to stabilize before the old values can be updated with new values.Hold down the clear/mode switch until "-4-" appears on the display area (for the switchgear conversion control panel). This enters the tattletale mode. The highest reading is for values that abnormally increase. The lowest reading is for values that abnormally decrease. Use the scroll switch. Advance the display area to the first tattletale value. The display area will momentarily show the system identifier "-PA-X-" or "-GA-X-". The display area will show the tattletale value. Press the scroll switch again for each succeeding tattletale value. Note: The system identifier "GA-X" is used only on 3406E generator sets. For the "PA-X" values and the "GA-X" values, refer to the Systems Operation, Testing and Adjusting, RENR2472, "Caterpillar Monitoring System for Electronic Modular Control Panel".Tattletale information is retained until the information in the memory of
