Diagnostic Example (1) First display. (2) Second display. (3) Module identifier (MID). (4) Service code indicator ("SERV CODE"). (5) Component identifier (CID). (6) Failure Mode identifier (FMI). Brief ExplanationIllustration 2 shows a main display module that is currently receiving a signal. This signal is from the transmission oil temperature sensor and the signal is out of the range.Detailed ExplanationMID (3) - "030". This code concerns the Caterpillar Monitoring System. The Caterpillar Monitoring System Service Manual should be used to troubleshoot the diagnostic code.CID (5) - "0110". This code means that a diagnostic code has occurred in the sensor circuit for the engine coolant temperature of MID "030". See the Table "Diagnostic Codes For Caterpillar Monitoring System" in Troubleshooting, "Diagnostic Code List". This will show a list of the CID and the FMI for the Caterpillar Monitoring System. FMI (6) - "08". This identifier means that a signal of abnormal frequency, pulse width, or period is being received concerning CID "0110". See the Table "Diagnostic Codes For Caterpillar Monitoring System" in Troubleshooting, " Diagnostic Code List". This table will show a list of FMIs for the Caterpillar Monitoring System.Service code indicator (4) is ON in Illustration 2. When the main display module is in service mode, the service code indicator (4) functions as a diagnostic code indicator. Therefore, the CID "0110" diagnostic code is present. The service code indicator changes from ON to OFF when the CID "0110" diagnostic code changes status. Also, the action alarm sounds when the CID "0110" diagnostic code changes status. This action will take place while the main display module is in service mode. Service ModesThe service modes allow service personnel to view and troubleshoot the system. Personnel can view and clear service code faults, view current display parameters, view and clear worst case (tattletale) values, and possibly run calibration routines of other modules connected to the CDL. The Default Modes configured are shown in Table 1.
