Cat Data Link
The Cat Data Link is used by the engine's ECM to communicate with Caterpillar controllers or display modules. Caterpillar Electronic Technician (ET) is a software program that is designed to run on a personal computer. Cat ET can be used by the service technician in order to view information about an event code that is generated by the engine's ECM. The following term describes the elements 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 Engine Oil Pressure
E360(2) Low Engine Oil Pressure
E360(3) Low Engine Oil PressureThree possible responses may be available for each parameter. Some of the responses are not available for some of the parameters. Refer to Table 1.
Table 1
Indicators (1), (2), and (3)
Warning Category Indicator Severity
(1) Least Severe
(2) Moderate Severity
(3) Most Severe The definition for the levels of severity for an event are defined below:Level (1) - Level (1) requires no immediate action. The system may need attention soon. The operator should check the involved system condition or the operator should perform maintenance on the involved system at the earliest possible time.Level (2) - Level (2) requires a change in the operation of the engine or the performance of a maintenance procedure. Failure to correct the problem that caused this warning may result in damage to the engine components.Level (3) - Level (3) requires an immediate safe shutdown of the engine in order to avoid damage to the engine or injury to personnel around the engine. The problem that caused the event must be corrected before engine operation can resume.Cross-Reference Information for Event Codes
Table 2 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. A further explanation of event codes and the engine's monitoring system are described after Table 2.

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:Level 1 - Level 1 alerts the operator that an engine system requires attention. The operator should check the involved system condition or the operator should perform maintenance on the involved system at the earliest possible time.Level 2 - Level 2 requires a change in the operation of the engine or the performance of a maintenance procedure. Failure to correct the problem that caused this warning may result in damage to the engine components.Level 3 - Level 3 requires an immediate safe shutdown of the engine in order to avoid damage to the engine or injury to personnel around the engine. The problem that caused the event must be corrected before engine operation can resume.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 g01785898
Example of the typical operating range of a sensor
(1) This area represents the normal operating range of the engine parameter.
(2) In this area, 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, "Diagnostic Trouble Codes" for additional information on diagnostic codes. 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:
