codes alert the operator that an abnormal engine operating condition such as low oil pressure or high coolant temperature has been detected. When the event code is generated, the event is active.The Electronic Control Module (ECM) can log events. Logged events usually indicate a mechanical fault instead of an electronic system fault or the engine is operating outside the design specification.Note: If a diagnostic code has already been logged then any associated event code to that fault will not be logged as well.
If an event code is already active, a diagnostic code that is associated with the same sensor will not be active.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.When certain event codes are activated, a warning will appear on the display on the control panel. Event code E361 High Engine Coolant Temperature will cause the warning lamp to illuminate on the control panel and a warning horn will sound. If equipped, the diagnostic lamp will flash the diagnostic code.Illustration 1 is an example of the operating range of an oil temperature sensor. Do not use the Illustration to troubleshoot the oil temperature sensor.

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 monitored parameter. The sensor circuit does not have an electronic problem. (3) In these areas, the signal from the sensor is outside of the operating range of the sensor. The sensor circuit has an electronic problem. A diagnostic code will be generated for the sensor circuit. Refer to Troubleshooting, "Self Diagnostics" for additional information on diagnostic codes.The following format is used for event codes:"EXXX (Y) Description of the event"The "E" means that the code is an event code. The "XXX" represents a numeric identifier for the event code. The "(Y)" represents a numeric identifier for the severity of the event. This is followed by a description of the event. Refer to the following example:"E362 (3) Engine Overspeed Shutdown"In this example, the number 3 indicates the severity of the event. The ECM has three levels of response to events:Level (1) - This level can be referred to as the "Warning Level". This condition represents a serious problem with engine operation. However, this condition does not require a derate or a shutdown.Level (2) - This level can be referred to as the "Derate Level". For this condition, the ECM reduces the power of the engine in order to help prevent possible engine damage.Level (3) - This level can be referred to as the "Shutdown Level". If engine shut down is enabled, the ECM will shut down the engine in order to prevent engine damage.Responses to certain events may be programmed into the
