Test Step 1. Check for Connector Damage.
Turn the breaker at the battery to the OFF position.
Turn the keyswitch to the OFF position.
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 not have corrosion, abrasion or pinch points.Results:
OK - The connectors and wiring are okay. Proceed to Test Step 2.
Not OK - The connectors and/or wiring are not okay.Repair: Repair the connectors or wiring and/or replace the connectors or wiring.STOPTest Step 2. Check for a Short Circuit in the Wiring Harness.Note: The circuit for the front engine begins with the letter T. The circuit for the rear engine begins with the letter R. The circuit for the master ECM begins with the letter X.
Disconnect ECM connector J1/P1 and all of the digital sensors if you are troubleshooting the digital supply for an exhaust temperature sensor. Disconnect the Master ECM connector J1/P1 and J2/P2 if you are troubleshooting the digital supply for the throttle position sensor.
Measure the resistance between the digital supply P1-35 (800-OR(Orange)) and the digital return P1-29 (998-BR(Brown)) on connector P1 if you are troubleshooting the digital supply for an exhaust temperature sensor. Measure the resistance between the digital supply P2-35 (X800-OR(Orange)) and the digital return P1-29 (X998-BR(Brown)) if you are troubleshooting the digital supply for the throttle position sensor.
Measure the resistance between the digital supply P1-35 (800-OR(Orange)) and the engine ground if you are troubleshooting the digital supply for an exhaust temperature sensor. Measure the resistance between the digital supply P2-35 (X800-OR(Orange)) and the engine ground if you are troubleshooting the digital supply for the throttle position sensor.
Measure the resistance between the digital return P1-29 (998-BR(Brown)) and the engine ground. Expected Result:The resistance should be 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.Repair: Repair the connectors or wiring and/or replace the connectors or wiring.STOPTest Step 3. Check the Digital Supply Voltage at the ECM.Note: The circuit for the front engine begins with the letter T. The circuit for the rear engine begins with the letter R. The circuit for the master ECM begins with the letter X.
Remove the wire P1-35 (800-OR(Orange)) from the harness side of ECM connector P1 if you are troubleshooting the digital supply for an exhaust temperature sensor. Install a wire jumper with
