Test Step 1. Check for Connector Damage.
Turn the circuit breaker for the battery to the OFF position.
Turn the keyswitch to the OFF position.
Disconnect the main power.
Thoroughly inspect the ECM connectors J1/P1 and J2/P2. Inspect all of the other connectors. Refer to the diagnostic functional test 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 2.25 0.25 N m (20 2 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. Expected Result:All connectors, pins, and sockets are completely coupled and/or inserted. The harness and wiring should be free of corrosion, of abrasion or of pinch points.Results:
OK - The connectors and the wiring are okay. Proceed to Test Step 2.
Not OK - The connectors and/or wiring need repair.Repair: Repair the connectors or wiring and/or replace the connectors or wiring.STOPTest Step 2. Check the Status of the Ground Level Shutdown Switch on the Cat ET.
Connect the Cat ET to the service tool connector.
Turn the circuit breaker for the battery to the ON position.
Turn the keyswitch to the ON position. The engine should be off.
Operate the ground level shutdown switch. Observe the status for the ground level shutdown switch on the Cat ET. Expected Result:The status of the ground level shutdown switch should read "ON" with the switch in the SHUTDOWN position. The status of the ground level shutdown switch should read "OFF" when the switch is in the RUN position.Results:
OK - The status of the ground level shutdown switch reads "ON" with the switch in the SHUTDOWN position. The status of the ground level shutdown switch reads "OFF" when the switch is in the RUN position. The ground level shutdown switch is operating normally.STOP
Not OK - The status of the ground level switch does not read "ON" with the switch in the SHUTDOWN position. The status of the ground level shutdown switch does not read "OFF" when the switch is in the RUN position. The ground level shutdown switch is not operating normally. Proceed to Test Step 3.Test Step 3. Short the Wires together at the Ground Level Shutdown Switch.Note: The circuit numbers for the front engine
