diagnostics for the Autodig system can be accessed through the monitor display or the Caterpillar Electronic Technician (ET). Troubleshooting the Autodig system requires additional information from the machine Service Manual. For troubleshooting use the additional manuals that may be required with the Electrical Schematic for the machine that is being serviced.When the troubleshooting procedure instructs you to "REPAIR THE HARNESS", use the Electrical System Schematic for the machine that is being serviced to trace the circuit. Perform continuity checks at the harness connectors to locate harness failures. At the connectors of the components, always check the ground circuit. Less than 5 ohms of resistance is required between the ground contacts of the connector and the frame ground. Excessive ground resistance that is greater than 5 ohms can cause incorrect diagnosing of problems.Failure of an electrical component can cause the failure of other components. Also, failure of electrical components can be caused by the failure of other components. Always attempt to correct the cause of an electrical system failure before you replace a component.Note: Before any tests are made to the Autodig system, operate the machine manually. Check the machine systems for correct operation. If any problems occur on manual operation, refer to the relevant machine systems section of the machine Service Manual for troubleshooting information.
