( 1 ) To use the CAT ET, order Special Publication, JERD2124, "ET Single Use Program License", Special Publication, JEHP1026, "Information and Requirements Sheet", and Special Publication, JERD2142, "Data Subscription". The Special Publication, JEHP1026, "Information and Requirements Sheet" lists the required hardware and the features of CAT ET.

Reference: For more information on troubleshooting with the Caterpillar Monitoring System, refer to the Service Manual module Testing and Adjusting, "Using Caterpillar Monitoring System to Determine Diagnostic Codes" for the machine that is being serviced.

Reference: For more information on troubleshooting with the Caterpillar Electronic Technician (ET), refer to the Service Manual module Testing and Adjusting, "Using Caterpillar Electronic Technician (ET) to Determine Diagnostic Codes" for the machine that is being serviced.

Use the digital multimeter for making continuity checks or for measuring voltage. For instructions about the use of the 6V-7070 Digital Multimeter, refer to Special Instruction, SEHS7734. The 7X-1710 Multimeter Probe is used in order to measure the voltage at the connectors without needing to disconnect the connectors. The probe cables are pushed into the back of the connector along the wire. The 8T-8726 Adapter Cable has a 3-pin connector. The adapter cable is used for measurements in the sensor circuits.

Note: Except for harness tests, using continuity testers such as the 8T-0500 Continuity Tester or voltage testers such as the 5P-7277 Voltage Tester is not recommended for today's Caterpillar electrical circuits.
