in the electronic system has been detected. Diagnostic codes are also used by the service technician to identify the nature of the problem. Caterpillar Electronic Technician (ET) is a software program that is designed to run on a personal computer. The software can be used by the service technician in order to view the diagnostic code information for
an Electronic Control Module (ECM). Diagnostic codes may consist of the component identifier (CID), and the failure mode identifier (FMI).
Component Identifier (CID) – The CID indicates the component that generated the code. For example, the CID number 1 identifies the fuel injector for the number one cylinder. Failure Mode Identifier (FMI) – The FMI indicates the type of failure. Refer to Table 1 for a complete list of the diagnostic codes and the appropriate troubleshooting
procedure. Note: Do not confuse diagnostic codes with event codes. Event codes alert the operator that an abnormal operating condition such as low oil pressure or high coolant temperature has been detected.

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. Note: This graphic is an example. The signal ranges in this graphic are
used only as examples. Active Diagnostic Codes An active diagnostic code represents a problem with the electronic control system. Correct the problem as soon as possible. When the engine’s ECM generates an active diagnostic code, the “Active Alarm” indicator (“Engine Control Alarm Status” on Cat ET) is activated in order to alert the operator. If
the condition that generated the code is momentary, the message disappears from the list of active diagnostic codes. The diagnostic code becomes logged. Logged Diagnostic Codes When the ECM generates a diagnostic code, the ECM logs the code in permanent memory.

If the condition that generated the code is momentary, the
message disappears from the list of active diagnostic codes. The diagnostic code becomes logged. Logged Diagnostic Codes When the ECM generates a diagnostic code, the ECM logs the code in permanent memory. The ECM has an internal diagnostic clock. Each ECM will record the following information when a 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 code This information is a valuable indicator for troubleshooting intermittent problems. A code is cleared from memory when one of the following conditions occur: The service technician manually clears the code. 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. Some diagnostic codes may be easily triggered. Some diagnostic codes may log occurrences that did not result in complaints. The most likely cause of an intermittent problem is a faulty connection or damaged wiring. The next likely cause is a component failure. The least likely cause is the failure of an
electronic module. Diagnostic codes that are logged repeatedly may indicate a problem that needs special investigation.
Note: Always clear logged diagnostic codes after investigating and correcting the problem which generated the code. About | Contact | Privacy Copyright © 2019 All rights reserved.
