P1 ECM connector (P1-3) Cat Data Link − (P1-9) Cat Data Link +Test Step 1. Inspect Electrical Connectors and Wiring
Turn the keyswitch to the OFF position.
Thoroughly inspect the ECM connectors J1/P1. Inspect all of the other connectors. Refer to Troubleshooting, "Inspecting Electrical Connectors" for details.
Perform a 45 N (10 lb) pull test on each of the wires in the ECM connector that are associated with the circuit.
Check the ECM connector (allen head screw) for the proper torque of 6.0 N m (55 lb in).
Check the customer connector (allen head screw) for the proper torque of 2.25 0.25 N m (20 2 lb in).
Check the harness and the wiring for abrasion and for pinch points.Note: Refer to the Electrical System Schematic for further information about the machine wiring.Expected Result:All connectors, pins, and sockets are completely coupled and/or inserted. The harness and wiring are free of corrosion, of abrasion, and of pinch points.Results:
OK - The harness and wiring are OK. Proceed to Test Step 2.
Not OK - There is a problem in the connectors and/or wiring.Repair: Repair the connectors or wiring and/or replace the connectors or wiring. Ensure that all of the seals are properly in place and ensure that the connectors are completely coupled.Verify that the repair eliminates the problem.STOPTest Step 2. Check for Shorts in the Harness
Disconnect ECM connector J1/P1 and ECM connector J2/P2.
Disconnect all modules from the Cat Data Link.
Disconnect Cat ET from the service tool connector.
Measure the resistance between P1-3 and every terminal on ECM connector P1 and ECM connector P2.
Measure the resistance from P1-3 to the chassis ground.
Measure the resistance between P1-9 and every terminal on ECM connector P1 and ECM connector P2.
Measure the resistance from P1-9 to the chassis ground.Expected Result:The resistance is greater than 20,000 Ohms for each measurement.Results:
OK - The resistance is greater than 20,000 Ohms. Proceed to Test Step 3.
Not OK - The resistance is less than 20,000 Ohms. There is a short circuit in the harness or connectors.Repair: Repair the connectors or wiring and/or replace the connectors or wiring.STOPTest Step 3. Check for an Open in the Harness
Use a suitable piece of wire to short J42-D to J42-E at the diagnostic connector.
Measure the resistance between P1-9 and P1-3.
Measure the resistance of the wires for the Cat Data Link at the other modules.Expected Result:The resistance is less than 5 Ohms for each measurement.Results:
OK - The resistance is less than 5 Ohms for each measurement. The Cat Data Link is OK.Repair: If the problem is intermittent, perform the diagnostic functional test Troubleshooting, "Inspecting Electrical Connectors".STOP
Not OK - The resistance is greater than 5 Ohms for each measurement. There is an open circuit in the harness or connectors.Repair: Repair the connectors or wiring and/or replace the connectors or wiring.STOPTest Step 4. Check Circuits with the Vital Information Management System (VIMS)
Check for shorts to ground between the connectors and/or wires of each VIMS module.
Check for opens in the wiring between VIMS modules. Short two wires together at the connector for the VIMS module. Check for an open between the wires by checking continuity between the wires at the connector of another module. Expected Result:The wires and connectors are free of shorts and opens.Results:
OK - The wires and connectors are free of shorts and opens.Repair: Reconnect all wires and connectors and check for proper operation.STOP
Not OK - The wires and connectors are free of shorts and opens.Repair: Repair the wires and/or connectors.STOP
