( 1 ) This multimeter can use an RS232C cable to connect to a laptop computer or Dataview tool gp for troubleshooting.Note: Caterpillar® Electronic Technician (Cat® ET) service tool is designed to run on a personal computer (PC) under Microsoft WindowsTo use Cat ET, the following materials must be ordered:
Special Publication, JERD2124, "ET Single Use Program License"
Special Publication, JEHP1026, "Information and Requirements Sheet"
Special Publication, JERD2142, "Data Subscription"The Special Publication, JEHP1026, "Information and Requirements Sheet" lists the required hardware and the features of Cat ET. For instructions on servicing Sure Seal connectors, see Special Instruction, SMHS7531. For instructions on servicing the Deutsch DT type connectors, see Special Instruction, SEHS9615.Cat ET is not required to view or clear the diagnostic codes. However, the process of determining the diagnostic codes is easier with Cat ET. Cat ET may also display the history and parameter status of a diagnostic code.Cat ET is used to communicate to the electronic control module (ECM) over the data link by connecting to the machine diagnostic connector. For more information about connectors, see Troubleshooting, "Electrical Components and Connector Locations" and the machine Electrical Schematic.For instructions on servicing Sure Seal connectors, see Special Instruction, SMHS7531. For instructions on servicing Deutsch connectors, see Special Instruction, SEHS9615.Use a calibrated digital multimeter to test continuity and voltage. See the instructions that are provided in the multimeter manual to operate the multimeter safely. The 7X-1710 Multimeter Probes are used to take measurements at a connector without separating the connections. The probe cables are pushed into the back of the connector along the wire. The 8T-8726 Adapter Cable has a three pin breakout and is used for sensor circuit measurements.Note: Use a 8T-0500 Continuity Tester and a 5P-7277 Voltage Tester to test a harness. Do not use a 8T-0500 Continuity Tester or a 5P-7277 Voltage Tester for electronic circuits.
