Warning Levels
The ECM will assign a warning level to an active event code. Event codes are one of three levels. The level is according to the severity of the abnormal condition. Each warning level requires a specific response from the operator. The warning levels and the required operator response are listed below.Warning Level 1
Warning level 1 alerts the operator that a machine system requires attention. The operator should check that the involved system condition or the operator should perform maintenance on the involved system at the earliest possible time.Warning Level 2
Warning level 2 requires changing the operation of the machine or performing a maintenance procedure. Failure to correct a problem that caused this warning may result in damage to the components involved in the system.Warning Level 2S
Warning level 2S requires an immediate change in machine operation in order to avoid possible damage to the system.Warning Level 3
Warning level 3 requires an immediate safe shutdown of the machine in order 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
Caterpillar Electronic Technician (Cat ET) Service Tool
When an abnormal operating condition occurs, the status screen on the Cat ET indicates that there is an active event.Event codes are displayed on Cat ET in the following format:EXXXX Description of the codeThe "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.List of Event Codes
The following table lists event codes and the recommended responses. Use the Cat ET service tool in order to determine the event codes that are active or logged.

EID Level Description Possible Cause and Recommended Response
861 1 Synchronized clock notification of manual synch required In a PL321 system using sync-clock and Product Link is not the master ECM, the Product Link module will automatically sync to the master ECM hours if the difference is not greater than 50 hours. If the difference is greater than 50 hours, a diagnostic will be generated in Cat ET that indicates that a manual sync is required. In that instance, sync the hours. In
