P2 ECM connector (P2-7) Solenoid return (P2-13) Engine oil renewal solenoidTest Step 1. Inspect Electrical Connectors and Wiring
Turn the keyswitch to the OFF position.
Thoroughly inspect the ECM connector J2/P2. Inspect all of the other connectors. Refer to 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 6.0 N m (55 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 are free of corrosion, of abrasion, and of pinch points.Results:
OK - The harness and wiring are OK. Proceed to Test Step 2.
Not OK - There is a problem in the 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. Check for an Internal Short or an Open in the Solenoid
Disconnect connector J113/P113 of the engine oil renewal solenoid.
Measure the resistance of the solenoid by measuring the resistance between J113-1 and J113-2.Expected Result:The resistance is between 24 and 53 Ohms.Results:
OK - The resistance is between 24 and 53 Ohms. The resistance is correct. Proceed to Test Step 3.
Not OK - The resistance is not between 24 and 53 Ohms. The resistance is incorrect.Repair: The solenoid is internally shorted or open. Replace the solenoid.STOPTest Step 3. Check the Voltage at the Engine Oil Renewal Solenoid
Connect the Caterpillar Electronic Technician (ET) to the cab service tool connector J42. Start Cat ET.
Turn the keyswitch to the ON position. The engine should be off.
Select the override for the engine oil renewal solenoid on Cat ET.
Set the override for the engine oil renewal solenoid to 100 percent.
Measure the voltage between P113-1 and P113-2.Expected Result:The voltage is greater than 8 VDC.Results:
OK - The voltage is greater than 8 VDC. The voltage is present at the connector.Repair: The voltage is reaching the solenoid. Check the mechanical operation of the solenoid.STOP
Not OK - The voltage is not greater than 8 VDC. The voltage is not present at the connector. Proceed to Test Step 4.Test Step 4. Check the Voltage at the ECM
Turn the keyswitch to the OFF position. The engine should be off.
Remove wire F701-BR from terminal P2-13 at ECM connector J2/P2. Install a wire jumper into the socket for P2-13.
Remove wire E799-BR from terminal P2-7 at ECM connector J2/P2. Install a wire jumper into the socket for P2-7.
Turn the keyswitch to the ON position. The engine should be off.
Select the override for the engine oil renewal solenoid on Cat ET.
Set the override for the engine oil renewal solenoid to 100 percent.
Measure the voltage between the jumper wires at P2-13 and P2-7.
Remove the jumper wires and reconnect all wires.Expected Result:The voltage is greater than 8 VDC.Results:
OK - The voltage is greater than 8 VDC. The voltage is correct. There is an open circuit or excessive resistance in the harness between the ECM and the solenoid.Repair: Repair the connectors or wiring and/or replace the connectors or wiring.STOP
Not OK - The voltage is less than 8 VDC. The voltage is incorrect.Repair: Replace the ECM. Refer to Troubleshooting, "Replacing the ECM".STOP
