Active Diagnostic Codes
An active diagnostic code represents a problem with the electronic control system that should be investigated and corrected as soon as possible.When an active diagnostic code is generated, a display module such as the Caterpillar Monitoring System may produce an audible or visible warning indicator to alert the operator. If the condition generating the diagnostic occurs only for a brief moment, the message will disappear and the diagnostic code will be Logged in the ECM memory.Logged Diagnostic Codes
When the ECM generates a diagnostic code, it usually logs the code in permanent memory within the ECM. The ECM has an internal diagnostic clock and will record the hour of the first occurrence, the hour of the last occurrence and the number of occurrences of the code.Knowing when and how often the code was generated can be a valuable indicator when troubleshooting intermittent problems. The ECAP Electronic Service Tool can be used but does not support all logged codes.An Electronic Service Tool can retrieve and delete Logged codes. Any Logged diagnostic codes will automatically be deleted if no additional occurrences are recorded in 100 hours.When investigating logged diagnostic codes, keep in mind the following information.* Some diagnostic codes may be sensitive, and may log occurrences that did not result in operator or pilot complaints. If the time the code was logged does not correlate to a complaint, there may be nothing to fix.* The most likely cause of an intermittent problem is a faulty connection or damaged wiring. Next likely is a component failure (sensor or switch). Least likely is failure of the ECM itself.* Diagnostic codes that are logged repeatedly may indicate a problem that needs special investigation.To troubleshoot a Logged diagnostic code, refer to the Quick Reference Sheet For Diagnostic Codes in this section. The code number will direct you to a procedure in Section 5: Functional Tests. If the symptoms continue, use the proper procedure for troubleshooting the symptoms that have been experienced by the operator. Refer to Section 3: Troubleshooting Without a Diagnostic Code. Always clear logged diagnostic codes after investigating and correcting the problem which generated the code.
Figure 4.15 - Reference: Output Voltage From An Analog Temperature Sensor The diagram shown is for reference only and should not be used to troubleshoot an analog Temperature Sensor.Logged Events
The ECM can log events. Events refer to engine operating conditions such as low oil pressure or high coolant temperature. Logged events do not indicate an electronic system problem, but may indicate an engine system problem. The example diagram shown indicates the output voltage from a Coolant Temperature Sensor and how the ECM responds to that voltage.Programmable Shutdown, Alarms And Derates
On some applications, shutdown, alarms and derates are programmable. The Electronic Service Tool can be used to turn these features ON and OFF. When the features are turned ON, the indication will appear on an electronic display module (i.e. Caterpillar Monitoring System) and an Event will also be logged in the ECM. When the features are turned OFF, the display will not appear on a monitoring module, but an Event will still be logged. Refer to Section 2 for additional information.Using ECAP To Display ACTIVE Or LOGGED Diagnostic Codes
1. Connect an ECAP and Communication Adapter Tool to the Service Tool connector.2. Turn the keyswitch to the ON position, engine OFF.3. Select the Display Diagnostics/Events option from the menu.4. Each diagnostic code CID and FMI are listed on the left and followed by a text description.5. The ECAP also displays number of times the diagnostic code occurs and the engine hours at the first and last occurrence of the diagnostic code.6. The diagnostic status display is located on the far right of the display window. (a) The ACTIVE bar indicates the diagnostic is occurring.(b) No text present, as shown on the first two diagnostics, indicates that two codes are logged but are not active.

Figure 4.18 - Example ET Logged Diagnostic Code ScreenComputerized Monitoring System Display
Computerized Monitoring System receives information from the ECM pertaining to engine oil pressure, coolant temperature, and engine rpm over the CAT data link. This information can be viewed by the operator on the Computerized Monitoring System display.The ECM can also communicate with the Computerized Monitoring System over the Cat data link when an ACTIVE diagnostic occurs or loss of coolant flow exists. The Computerized Monitoring System can illuminate the proper lamp for the given condition. The Check Engine Lamp will only be illuminated when the ECM determines that an ACTIVE diagnostic conditions exists. Refer to the Computerized Monitoring System Service Manual for more information on the Computerized Monitoring System display.The ECM can not determine if the information it is sending is being received by the Computerized Monitoring System. Should there be a problem with communications between the ECM and the Computerized Monitoring System, the following conditions can be observed on the Computerized Monitoring System display:* The Oil Pressure Gauge will flash.* The Coolant Temperature Gauge will flash.* The Tachometer will flash and a digital reading of 3000 rpm will be displayed.* The Check Engine Lamp will be ON.* The Coolant Flow Lamp will be ON.Using Computerized Monitoring System Electronic Display Module To Display ACTIVE Or LOGGED Diagnostic Codes
