Turn the keyswitch to the OFF position.
Thoroughly inspect the J1/P1 connectors on the Electronic Control Module (ECM), the switch connections and battery connections. Refer to Troubleshooting, "Electrical Connectors - Inspect" for details.
Perform a 45 N (10 lb) pull test on each of the wires in the sensor connector and the ECM connector that are associated with the active diagnostic code. Refer to illustration 2.
Verify that the latch tab of the connector is correctly latched. Also verify that the latch tab of the connector has returned to the fully latching position.
Check the screw for the ECM connector for the correct torque of 6 N m (53 lb in).
Check the harness for corrosion, abrasion, and pinch points from the PTO mode switches to the ECM.Expected Result:All connectors, pins, and sockets are correctly connected. The harness should be free of corrosion, abrasion, and pinch points.Results:
