Cross-Reference Information for Event Codes
Table 1 is a list of the event codes for the engine. The event codes are cross-referenced with the appropriate procedure that can be used to troubleshoot the code.Event codes are generated when abnormal operating conditions exist. A further explanation of event codes and the engine's monitoring system are described after Table 1.

An event code represents a problem with the operating condition of the engine. Correct the problem as soon as possible.Each event has a trip point. The trip point is a value that is out of the normal operating range for a system such as the engine cooling system or the lubrication system. Once the trip point has been exceeded, the Electronic Control Module (ECM) will count down the trip delay for the code. Once the trip delay expires, the code will be logged. The trip delay is the amount of time before the ECM will act on the code. This delay helps to ensure that the condition is valid. There is also a start delay that prevents the ECM from mistakenly generating event codes during engine start-up. The start delay is the amount of time after the engine starts before an event code can be generated. Once the system falls below the reset level and the reset delay expires, the event will become inactive.In the format for an event code, the "E" is used to identify the code as an event code. The first three numbers "XXX" represent a numeric identifier for the event code. The fourth "(X)" identifies the event as a warning, a derate, or a shutdown. This is followed by a description of the code. Refer to the following example:
E360(1) Low Oil Pressure Warning
E360(2) Low Oil Pressure Derate
E360(3) Low Oil Pressure ShutdownThe definition for a warning, a derate, and a shutdown are defined below:Warning (1) - This condition represents a serious problem with engine operation. However, this condition does not require a derate or a shutdown.Derate (2) - For this condition, the engine's power is reduced in order to help prevent possible engine damage. However, this condition does not require a shutdown.Shutdown (3) - For this condition, the operator is alerted of the event. The operator must shut down the engine in order to prevent possible engine damage.

Output voltage from a typical temperature sensorIllustration 1 shows the typical output voltage from an analog sensor. If the output signal voltage is between 4.2 VDC and 4.8 VDC, the ECM will generate an event code.These responses to certain events may be programmed into the ECM. If the responses are programmed, Caterpillar Electronic Technician (ET) can display the event. If the responses are not programmed, the display will not appear. However, the occurrence of any event will cause the event code to be logged in the ECM.Note: Do not confuse event codes with diagnostic codes. For information on diagnostic codes, refer to Troubleshooting, "Troubleshooting with a Diagnostic Code".Logged Event Codes
When the ECM generates an event code the code is logged into permanent memory. The ECM has an internal diagnostic clock that is used to time stamp the activation of the event. The ECM will record the following information when an event code is generated:
The hour of the first occurrence of the code
The hour of the last occurrence of the code
The number of occurrences of the codeLogged events are listed in chronological order. The most recent event code is listed first.This information can be helpful for troubleshooting intermittent problems. Logged codes can also be used to review any performance problems with the engine.Clearing Event Codes
A code is cleared from memory when one of the following conditions occur:
The code does not recur for 100 hours.
A new code is logged and there are already ten codes in memory. In this case, the oldest code is cleared.
The service technician manually clears the code.Always clear logged event codes after investigating and correcting the problem which generated the code.Troubleshooting
For basic troubleshooting of the engine, perform the following steps in order to diagnose a malfunction:
Obtain the following information about the complaint:
The event and the time of the event
Determine the conditions for the event. The conditions will include the engine rpm and the load.
Determine if there are any systems that were installed by the dealer or by the customer that could cause the event.
Determine whether any additional events occurred.
Verify that the complaint is not due to normal engine operation. Verify that the complaint is not due to error of the operator.
Narrow the probable cause. Consider the operator information, the conditions of operation, and the history of the engine.
Perform a visual inspection. Inspect the following items:
Condition of the fuel and
