Electronic Control Module (ECM)
Illustration 1 g01060444
Test Step 1. Inspect Electrical Connectors and Wiring
Turn the keyswitch OFF/RESET.
Thoroughly inspect the J61/P61 customer connector, the J1/P1 ECM connector, and the J2/P2 ECM connector. Refer to Troubleshooting, "Electrical Connectors - Inspect" for details.
Perform a 45 N (10 lb) pull test on each of the wires in the customer connector and the ECM connector that are associated with the diagnostic lamp. Refer to illustration 1.
Check the J61/P61 customer connector (allen head screw) for the proper torque of 2.25 0.25 N m (20 2 lb in).Check the ECM connector J1/P1 and J2/P2 for the proper torque of 6.0 N m (55 lb in).
Check the harness and wiring for abrasions and for pinch points from the battery to the ECM.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 wiring and connectors are okay. Proceed to Test Step 2.
Not OK - 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. Stop.Test Step 2. Verify the Negative Battery Connections
Locate the negative battery bus bars and verify that the connections are installed properly.Refer to Troubleshooting, "Engine Wiring Information" for additional information.Expected Result:The negative battery connections have been properly installed.Results:
OK - The connections for the negative battery bus bar have been installed properly. Proceed to Test Step 3.
Not OK - Repair: Make the necessary connections in order to ensure proper installation. Stop.Test Step 3. Check the Status of the Switch
Connect the electronic service tool to the service tool connector.
Turn the keyswitch to the ON position.
Monitor the status screen on the electronic service tool while each switch is cycled.Expected Result:Each switch is displayed as "ON" and "OFF" when the switch is cycled.Results:
OK - The switches are operating properly. Stop.
Not OK - There is a problem with the wiring or the switch. Proceed to Test Step 4.Test Step 4. Bypass the Switch
Make a jumper wire that is 100 mm (4 inch) long. Use two 9W-0852 Connector Pin on the ends of the wire.
Turn the keyswitch to the OFF/RESET position.
Install the jumper wire across the switch that is suspect.
Turn the keyswitch to the ON position.
Monitor the status screen on the electronic service tool for the suspect switch.Expected Result:The switch status changes for the suspect switch.Results:
OK - The switch status changed.Repair: Replace the switch.Verify that the repair solved the problem. Stop.
Not OK - The switch status did not change. Proceed to Test Step 5.Test Step 5. Check the Negative Battery Wiring for the Suspect Switch
Turn the keyswitch to the OFF/RESET position.
Measure the resistance between the negative battery terminal on the suspect switch and a negative battery connection that is in close proximity. Check in order to ensure that the negative battery connection is good.Expected
