Event codes alert the operator or the technician that an abnormal operating condition exists in one of the machine systems.
When the Machine ECM activates an event code, the operator or the technician will be alerted. Most active events will be logged by the ECM. Some events are not logged to the ECM. The active events and the logged events can be viewed with the Operator Monitor or the Cat® Electronic Technician (Cat ET)
The ECM will assign one of the three warning levels to an active event code according to the severity of the abnormal system condition. Each warning level requires a specific response from the operator. The warning levels and required operator response are listed below.
Warning Level 1 alerts the operator that a machine system requires attention. The operator should check the involved system. Perform any necessary maintenance to the system at the earliest possible time.
Warning Level 2 requires changing the operation of the machine or performing a maintenance procedure. Failure to correct the problem behind this warning will damage the components that are involved. The problem that caused the event requires correction, before the machine can resume operation.
Warning Level 3 requires an immediate safe shutdown of the machine to avoid damage to the machine or injury to personnel around the machine. The problem that caused the event must be corrected before machine operation can resume.
Indications and System Response
When an abnormal operating condition occurs, the Active fault LED on the Operator Console or Cat ET indicates that there is an active event.
Event codes are displayed on Cat ET 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.

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 has not reoccurred for 150 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.
Perform the following steps in order to troubleshoot 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 before and after 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 by the operator.
- Check all fluid levels and all oil levels.
- Troubleshoot and repair any active diagnostic codes.
The following table lists the event codes that apply to the control system of the machine. The recommended response is listed. Use the Cat ET service tool to determine the event codes that are active or logged.
