(1) For troubleshooting, see the procedure with the same CID FMI.Note: A machine ECM will self-erase a diagnostic if the diagnostic does not reappear after 100 operating hours. When this event happens, the event history screen in the EquipmentManager application will show a code that occurred 100 hours in the past that no longer shows up in Cat ET because the diagnostic has not reoccurred.
