Cat ET
When an abnormal operating condition occurs, the status screen on the Operator Monitor or Cat ET indicates that there is an active event.Event codes are displayed on Cat ET or the monitor in the following format:EXXXX -- (Description of the code)The "E" means that the code is an event code. The "XXXX" is a numeric identifier. The numeric identifier is followed by a description of the code. Active event codes are listed in ascending numerical order. The code with the lowest number is listed first. The active event code is removed from the list when the condition is no longer present.Logged Event Codes
Some event codes are logged in the ECM memory. Some event codes are active only. The logged event codes are listed in chronological order. The most recent code is listed first.A logged code is cleared from memory when one of the following conditions occur:
The service technician manually clears the code.
The code does not reoccur for 1000 hours.
A new code is logged and there are already ten logged codes in memory. In this case, the oldest logged code is cleared.Note: Always clear logged event codes after investigating and correcting the problem which generated the code.Troubleshooting
Perform the following steps when troubleshooting an event:
Obtain the following information from the operator monitor and the machine operator:
The event and the time of the event
Determine the operating conditions for the engine at the time of the event. Conditions such as engine RPM and load may be important.
Determine if there are any systems that were installed by the dealer or by the customer that could cause the event.
Some of the events below can become active during normal system operation. Verify that the event is not due to error of the operator.
Check all fluid levels and all oil levels.
Troubleshoot and repair any active diagnostic codes. Machine ECM Event Code List
