Caterpillar Monitoring System Display Components (1) Quad gauge electronic module (2) Speedometer/tachometer module (3) Tachometer (4) Main display module (5) Alert indicators (6) Hazard indicator (7) Speed readout (8) General indicators (9) Gear readout (10) Action Lamp (11) Gauges (12) Display areaNote: The 834G Wheel Tractor display components are shown. The 836G Landfill Compactor is similar.The Caterpillar Monitoring System sends input to the power train electronic control module (ECM). The power train ECM sends output to the Caterpillar Monitoring System. The Caterpillar Monitoring System and the power train ECM communicate back and forth on the CAT Data Link.The Caterpillar Monitoring System indicates the status of basic functions of the machine. This includes the power train system.The power train ECM receives the harness code input from the Caterpillar Monitoring System. The power train ECM determines the sales model of the machine from the harness code input. The power train ECM receives a service command from the Caterpillar Monitoring System. The service command can change the operating mode of the power train electronic control system. The service command can direct the power train ECM to read service codes that are stored in the ECM memory. The service command can direct the power train ECM to clear service codes that are stored in the ECM memory.A Warning Category 3 alerts the operator that engine shutdown should occur as soon as possible. This helps prevent injury to the operator or potential damage to the machine.A Warning Category 3 causes both action lamp (10) and alert indicator (5) to flash. A Warning Category 3 also causes the action alarm to sound.Note: Do NOT operate the machine until the cause of the warning has been corrected.For the power train system, the Caterpillar Monitoring System problems that can activate alert indicators (5) follow. Problems that appear below in bold text indicate a possible Warning Category 3.
