( 1 ) A CID for the new software has four digit numbers.Troubleshooting the Caterpillar Monitoring System requires additional information from the engine Service Manual. The Electrical System Schematic, the Electronic Troubleshooting Guide, the Parts Manual and the Operation & Maintenance Manual are materials that are required for support.When the troubleshooting procedure instructs the operator to repair the harness, use the Electrical System Schematic in the engine Service Manual to trace the circuit. Less than 5 ohms of resistance is required between the connector and ground. Ground resistance that is greater than 5 ohms can cause incorrect diagnosing of problems.During troubleshooting, inspect all components and harness connections before any component is replaced. If these connections are not clean and tight, the connections can cause permanent electrical problems or intermittent electrical problems. Check that the wires are pushed into the connectors all the way. Perform a pull test on the connector and the wires in order to confirm that the contacts are snapped into place. Make sure that the connections are tight before any other tests are performed. Problems with one electrical component can cause problems with one or more other electrical components. The operator should always attempt to find the cause of the electrical system problems and the operator should correct the cause of the electrical system problems before the operator replaces the component.
