P1 ECM connector (P1-22) Emergency stop switch (P1-23) Maintenance clear switch (P1-40) Diagnostic reset switch (P1-47) Low idle switchTest Step 1. Inspect Electrical Connectors and Wiring
Turn the keyswitch OFF.
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, and the harness and wiring are free of corrosion, of abrasion and of pinch points.Results:
OK - The connectors and wiring are OK. Proceed to Test Step 2.
Not OK - There is a problem with the electrical 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. 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 - The connections for the negative battery bus bar have not been installed properly.Repair: Make the necessary connections in order to ensure proper installation. Proceed to Test Step 3.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. Install a Jumper at the Customer Connector and Check the Status of the Switch
Turn the keyswitch to the OFF position.
Fabricate a jumper wire that will reach from the negative battery bus bar to the J61 customer connector.
Install a 9W-0844 Connection Socket on one end of the jumper wire and a connector that will connect to the negative battery bus bar on the opposite end.
Connect the jumper wire from the negative battery bus bar to the pin for
