EXTENSION A 1H6163 - Caterpillar

The Caterpillar Monitoring System is an input and an output of the power train ECM. These two electronic controls communicate back and forth on the CAT data link. The Caterpillar Monitoring System provides alert indicators, gauges, and numerical readouts for the power train ECM to use. The Caterpillar Monitoring System receives information from the power train ECM. Then, the Caterpillar Monitoring System displays the following information:
Problems with the steering system that are shown on the alert indicator for steering system status (5)
Problems with the braking system that are shown on the alert indicator for braking system status (6)
Problems with the transmission system that are shown on the alert indicator for the transmission system (7)
Status of the parking brake that is shown on the alert indicator for parking brake status (9)
The Status of the gears ("1R", "N", and "1F") that are shown in display area (23)
Diagnostic codes that are shown in display area (23)
Implement L.O.
Problem with the implement system.The status of the oil temperature for the outlet of the torque converter is displayed on one of the gauges. A problem with the power train oil filter is shown on alert indicator (8). The information for the oil filter and for the oil temperature is not provided by the power train ECM. The Caterpillar Monitoring System has a temperature sensor for the oil temperature of the outlet of the torque converter. The Caterpillar Monitoring System also has a pressure switch for the power train filter. The Caterpillar Monitoring System sends the information about the harness code to the power train ECM. This information informs the power train ECM of the sales model of the machine. The Caterpillar Monitoring System also sends service commands to the power train ECM. The service commands cause the power train ECM to change operating modes. The service commands also cause the power train ECM to read diagnostic codes and clear diagnostic codes that are stored in the memory of the power train ECM.The power train ECM uses the main display module on the Caterpillar Monitoring System for showing diagnostic information to service personnel. Diagnostic information concerning the power train system is sent on the CAT data link to the Caterpillar Monitoring System. Service personnel must be familiar with the Caterpillar Monitoring System in order to troubleshoot the Power Train Electronic Control System. The Caterpillar Monitoring System has several different modes of operation. For troubleshooting and calibrating the Power Train Electronic Control System, service personnel must place the Caterpillar Monitoring System in certain modes of operation. The operator mode selector switch and the 4C-8195 Control Service Tool are used for changing the display modes of the monitor. The operator mode selector switch allows personnel to view certain machine information. The operator mode selector switch is on the front dash. Pressing the operator mode selector switch will change display area (23). Display area (23) will display different information that is available. The operator mode selector switch is functional only when the monitor is
