(1) Display menu (2) "Four way" button (3) OK button (4) "Back to previous screen" button (5) Return to main menuThe display module can display events and codes in the service mode. The codes and events are reported by the Electronic Control Module (ECM).The diagnostic codes and events can be viewed in the service mode. Access the service mode by using the following steps. Go to the main menu by pressing the menu button (5). The main menu (1) will appear on the display module. Scroll to "service" with the 4 way button (2). Press the "OK" button (3) in order to view the service menu. Access the diagnostic mode with the "OK" button from the service menu. The events, active codes and logged codes will now be displayed. The codes and events can be viewed in more detail by pressing the "OK" button again. View all codes and events on the list by pressing the 4 way button. Exit the service mode by pressing the main menu button (5) .The following list contains some of the functions of the display module.
The diagnostic codes of the ECM systems are displayed.
The settings for the ECM are displayed.
The machine status parameters are shown in real time.
The number of occurrences and the clock hour of the first occurrence and the last occurrence are displayed for each of the events, active codes and logged codes.
The definition for each logged diagnostic code and each event is displayed.Troubleshooting Procedures
The diagnostic codes can be viewed with the following systems: the Display Module and the Caterpillar Electronic Technician (ET). See one of the following references:The following procedures may cause new diagnostic codes to be logged. Therefore, before any procedures are performed make a list of all the active diagnostic codes in order to determine the system problems. Clear the diagnostic codes that were caused by the procedure, when each procedure is complete.Note: Before performing a procedure, always check all the circuit breakers. Repair the cause of any circuit breaker that is tripped.Event Identifier (EID)
An event indicates a reading that is outside of normal operating ranges but within component limits. The data is incorrect but there is no fault in the component. An example might be a high oil temperature reading. The event will be identified by the ECM, the EID and a time stamp.Component Identifier (CID)
The component identifier is a four digit number that represents a particular component on the machine. For example, each solenoid that is connected to the Machine ECM has a number that is assigned. See Troubleshooting, "Diagnostic Code List" for a list of all of the components of the machine control system.Failure Mode Identifier (FMI)
The codes for the Failure Mode Identifier are defined by the SAE standards. The following list contains a CAT version of definitions. The diagram that follows will help you understand the use of FMI with sensors.
