Alert Indicators For AP-655C (1) Left Track Take Up Pressure. (2) Right Track Take Up Pressure. (3) System Voltage. (4) Unused. (5) Operator Error. (6) Hydraulic Oil Level Low. (7) Hydraulic Oil Filter Restricted. (8) Propulsion System Fault. (9) Material, Tamp & AUX System Fault. (10) Burner System Fault. The main display module of the Caterpillar Monitoring System is used to show information. A mode select switch is provided on the inside of the center console. Momentarily pushing the switch will allow the operator to scroll through the numeric readout modes that are listed below:
Engine speed
Hour meter
Tamper bar speedNote: The unit indicators are automatically turned ON or OFF in order to correspond with the information that is shown on the numeric display. The values for the "odometer" may be displayed in either English units or metric units. Toggling between English and metric units can be performed with the mode select switch or the ET. When the display is in the metric mode the display will show the machine speed in meters per minute up to 199 meters per minute. When the machine speed exceeds 199 meters per minute the units will change to km/h. When the display is in the English Mode the readout shows the machine speed in ft/min up to 199 ft/min. When the machine speed exceeds 199 ft/min the units will change to mph.Diagnostic codes
The operator mode switch may be used to view the active diagnostic codes and the logged diagnostic codes. The serv code indicator will be illuminated while active fault codes are displayed. The serv code indicator will be OFF while logged diagnostic codes are displayed. Diagnostic codes can also be displayed through use of the Caterpillar Electronic Technician (ET). The Caterpillar Electronic Technician (ET)

The Caterpillar Electronic Technician (ET) is a software program that is used to access data. The service technician will use the ET in order to perform the maintenance on the machine. Some of the options that are available with the Caterpillar Electronic Technician are listed below:
Diagnosis of problems
Viewing diagnostic codes
Viewing active event codes and logged event codes
View the status of parameters.
Clear active diagnostic codes and clear logged diagnostic codes
Perform calibration of machine systems.
Program the ECM (Flash). This is done with the "WINflash" program. See Troubleshooting, "Electronic Control Module (ECM) - Flash Program".
Print reports.See Troubleshooting, "Using the Caterpillar Electronic Technician to Determine Diagnostic Codes". Diagnostic information is accessed with the following drop down menus:
Active diagnostic codes
Logged diagnostic codesLogged Event Codes

Typical ET screenLogged events are provided with an indicator which is used to keep track of recurring or intermittent events. The data for the logged event shall include the following items: an event identifier (EID), a text description of the event, the number of occurrences of the event, a time stamp that
