Engine Monitoring
The Electronic Control Module (ECM) monitors the operating parameters of the engine. The ECM will generate an event code if a specific engine parameter exceeds an acceptable range that is defined by the engine monitoring system. For information on the engine monitoring system, refer to Troubleshooting, "Engine Monitoring System".Cross-Reference Information for Event Codes
Event codes are generated when abnormal operating conditions exist. 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.

Cross-Reference from Event Codes on Cat Data Link to Troubleshooting Procedure
Code and Description Troubleshooting Procedure
E096(1) High Fuel Pressure Troubleshooting, "Fuel Pressure Is High"
E098(1) Engine Pre-lube Override The keyswitch has been cycled from the ON position to the OFF position back to the ON position in one second or less. The prelube cycle has been overridden.
E172(1) High Air Filter Restriction Check the air intake for restrictions.
Inspect and clean the air filter or replace the air filter.
E172(2) High Air Filter Restriction
E194(1) High Exhaust Temperature Troubleshooting, "Exhaust Temperature Is High"
E233(1) Low Engine Pre-Lube Pressure The oil pressure must be equal to the pressure that is set in the software. If the oil pressure is less than the oil pressure in the software and the prelube timer has timed out, the code will be generated.
E265(1) User-Defined Shutdown Troubleshooting, "Engine Shutdown Occurrence"
E268(1) Unexpected Engine Shutdown Troubleshooting, "Engine Shutdown Occurrence"
E360(3) Low Engine Oil Pressure Troubleshooting, "Oil Pressure Is Low"
E361(2) High Engine Coolant Temperature Troubleshooting, "Coolant Temperature Is High"
E361(3) High Engine Coolant Temperature
E362(2) Engine Overspeed Troubleshooting, "Engine Overspeeds"
E362(3) Engine Overspeed
E363(1) High Fuel Supply Temperature Troubleshooting, "Fuel Temperature Is High"
E390(1) Fuel Filter Restriction Troubleshooting, "Fuel Filter Is Restricted"
E540(1) Low Engine Oil Refill Tank Level Troubleshooting, "Oil Level - Test"
E1001(1) High Right Intake Manifold Air Temperature Troubleshooting, "Inlet Air Temperature Is High"
E1001(2) High Right Intake Manifold Air Temperature Parts of the Event Code
Event Code - The "E" identifies the code as an event code. The "XXX(X)" represents a numeric identifier for the event code. The fourth "(X)" assigns one of three levels to the active event code according to the severity of the abnormal system condition. This is followed by a description of the code. Refer to the following example:
E360(1) Low Oil Pressure
E360(2) Low Oil Pressure
E360(3) Low Oil PressureThe definition for the levels of severity for an event are defined below:
Table 2
Indicators (1), (2), and (3)
Warning Category Indicator Severity
(1) "Least Severe"
(2) "Moderate Severity"
(3) "Most Severe" Active Event Codes
An active event code represents a problem with engine operation. Correct the problem as soon as possible.Active event codes are listed in ascending numerical order. The code with the lowest number is listed first.Illustration 1 is an example of the operating range of a sensor.
Illustration 1 g01365757
Example of the typical operating range of a sensor
(1) This area represents the normal operating range of the engine parameter.
(2) In these areas, the engine is operating in an unsafe operating range of the monitored parameter. An event code will be generated for the
