SchematicTest Step 1. Inspect Electrical Connectors and Wiring
Turn the keyswitch to the OFF/RESET position.
Thoroughly inspect the J1/P1 ECM connector and all other connectors in the wiring harness. Refer to Troubleshooting, "Electrical Connectors - Inspect" for details.Note: Refer to the Electrical System Schematic for further information about the machine wiring.Expected Result:All connectors, pins, and sockets are completely inserted and coupled. The harness and wiring are free of corrosion, of abrasion, and of pinch points.Results:
OK - Proceed to Test Step 2.
Not OK - Repair: Repair the circuit.Verify that the repair eliminates the problem. Stop.Test Step 2. Check for Shorts in the Harness

P1 ECM connector
Disconnect the J1/P1 ECM connector.
Disconnect all modules from the CAT Data Link.
Disconnect Cat ET from the service tool connector.
Measure the resistance between P1:3 (CAT Data Link -) and P1:9 (Cat Data Link +).
Measure the resistance between P1:9 (Cat Data Link +) and chassis ground.
Measure the resistance between P1:3 (CAT Data Link -) and chassis ground.Expected Result:The resistance is greater than 20,000 Ohms for each measurement.Results:
OK - Proceed to Test Step 3.
Not OK - There is a short circuit in the harness or connectors.Repair: Repair the circuit.Verify that the repair eliminates the problem. Stop.Test Step 3. Check Resistance Through the Harness

P1 ECM connector
Use a suitable piece of wire to short J42:D (CAT Data Link +) and J42:E (CAT Data Link -) at the service tool connector.
Measure the resistance between P1:9 (CAT Data Link +) and P1:3 (CAT Data Link -).
Measure the resistance across the CAT Data Link at the other modules.Expected Result:The resistance is less than 10 Ohms for each measurement.Results:
OK - The CAT Data Link is OK.Repair: Refer to Troubleshooting, "Electrical Connectors - Inspect" if the problem is intermittent. Stop.
Not OK - There is an open circuit or excessive resistance in the harness or connectors.Repair: Repair the circuit.Verify that the repair eliminates the problem. Stop.
