Active Diagnostic Codes
An active code indicates that an electrical problem is present. Service the active code first. For the appropriate troubleshooting procedure for a diagnostic code, refer to Troubleshooting, "Diagnostic Trouble Code List".Logged Diagnostic Codes
The codes are logged and stored in the ECM memory. The problem may have been repaired and/or the problem may no longer exist. If the system is powered, it is possible to generate an active diagnostic code whenever a component is disconnected. If the component is reconnected, the code is no longer active but the code may become logged.Logged codes may not indicate that a repair is needed. The problem may have been temporary. Logged codes may be useful to help troubleshoot intermittent problems. Logged codes can also be used to review the performance of the engine and of the electronic system.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 temperature sensor. Do not use the Illustration to troubleshoot temperature sensors.
Illustration 1 g01138880
Example of the typical operating range of a temperature sensor (1) This area represents the normal operating range of the parameter. The normal output voltage of the sensor is between 0.2 VDC and 4.2 VDC. (2) In this area, the temperature above 107 °C (225 °F) is higher than normal. The output voltage of the sensor will generate an event code. The sensor does not have an electronic problem. (3) In these areas, the output voltage of the sensor is too high or too low. The voltage is outside of the normal range. The electronic problem will generate a diagnostic code. Refer to Troubleshooting, "Diagnostic Trouble Code List" for additional information on diagnostic codes.Events are represented in two formats. In the first format, the "E" means that the code is an event code. The "XXX(X)" represents a numeric identifier for the event code. This is followed by a description of the code. If a warning, a derate, or a shutdown is applicable, the numeric identifiers are different. Refer to the following example:
E004(3) Engine Overspeed Shutdown
E190(1) Engine Overspeed WarningIn the second format, the "E" means that the code is an event code. The "XXX(X)" represents 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 - This condition represents a serious problem with engine operation. However, this condition does not require a derate or a shutdown.Derate - For this condition, the engine's Electronic Control Module (ECM) reduces the engine's power in order to help prevent possible engine damage.Shutdown - For this condition, the ECM shuts down the engine in order to help prevent possible engine damage.Logged Event Codes
When the ECM generates an event code the ECM logs the code in permanent memory. The ECM has an internal diagnostic clock. 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 the performance of 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.
