From the "Service Menu", use the appropriate "ARROW" button to highlight the "Diagnostics" option, then press the "OK" button in order to access the "Diagnostics "screen.
The "Diagnostics screen" shows a complete list of all active and logged diagnostic codes. Each line on the list shows the "MID, CID, and FMI". Also the display shows the number of "OK" occurrences, the time (service hour) of the first occurrence and the last occurrence of the code or event, and whether it is currently active. From the "Diagnostics screen", use the appropriate "ARROW" button to display that line's "Detailed View". The "Detailed View" will display a text message showing the reporting ECM (MID), identify the failed component (CID), and provide an explanation of the failure, such as System Voltage Below Normal (FMI).
Note: The codes and events that are displayed in the Diagnostics option may be viewed at any time. Press the button to highlight a specific code (line on the list). Fault codes that originate from the Advisor module must be cleared through Advisor. This action does not require the use of a password. Fault codes other than those issued through the Advisor module must be cleared through Caterpillar ET.
