(P1-11) Engine oil renewal solenoid Test Step 1. Inspect Electrical Connectors and Wiring
Remove the electrical power from the ECM.
Thoroughly inspect the ECM connector J1/P1. Inspect all of the other connectors for the circuit. Refer to the diagnostic functional test Troubleshooting, "Electrical Connectors - Inspect".
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. Refer to the diagnostic functional test Troubleshooting, "Electrical Connectors - Inspect".
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 Active Diagnostic Codes
Connect Caterpillar Electronic Technician (ET) to the service tool connector.
Restore the electrical power to the ECM.
Monitor the active diagnostic code screen on Cat ET. Check and record any active diagnostic codes. Note: Wait at least 30 seconds in order for the diagnostic codes to become active.
Determine if the problem is related to an open circuit diagnostic code (05) or a short circuit diagnostic code (06). Expected Result:No diagnostic codes are active.Results:
OK - No diagnostic codes are active.Repair: The problem may have been related to a faulty connection in the harness. Carefully reinspect the connectors and wiring. Refer to the diagnostic functional test Troubleshooting, "Electrical Connectors - Inspect".STOP
Not OK - A short circuit diagnostic code (06) is active at this time. Proceed to Test Step 3.
Not OK - An open circuit diagnostic code (05) is active at this time. Proceed to Test Step 4.Test Step 3. Disconnect the Connector for the Engine Oil Renewal Solenoid in Order to Create an Open Circuit
Remove the electrical power from the ECM.
Disconnect the connector for the engine oil renewal solenoid.
Restore the electrical power to the ECM. Wait at least 30 seconds for activation of the diagnostic codes.
Access the "Active Diagnostic Code" screen on Cat ET. Check for an active open circuit diagnostic code (05) for the engine oil renewal solenoid.
Remove the electrical power from the ECM. Expected Result:An open circuit diagnostic code (05) is now active for the engine oil renewal solenoid.Results:
OK - A short circuit diagnostic code (06) was active before disconnecting the connector. An open circuit diagnostic code (05) became active after disconnecting the connector.Repair: Temporarily connect a new engine oil renewal solenoid to the harness, but do not install the new engine oil renewal solenoid. Verify that there are no active diagnostic codes for the solenoid. If there are no active diagnostic codes for the solenoid, permanently install the new solenoid. Clear any logged diagnostic codes.STOP
Not OK - There is a short circuit between the solenoid harness connector and the ECM. Leave the solenoid connector disconnected. Proceed to Test Step 5.Test Step 4. Create a Short at the Connector for the Engine Oil Renewal Solenoid
Remove the electrical power from the ECM.
Install a jumper wire with Deutsch sockets on each end between terminal 1 (engine oil renewal solenoid) and terminal 2 (solenoid return) on P506. Connect the jumper on the harness side of the connector.
Restore the electrical power to the ECM.
Wait at least 30 seconds for activation of the short circuit diagnostic code (06). Note: Monitor the "Active Diagnostic Codes" screen on Cat ET before installing the jumper wire and after installing the jumper wire.
Remove the jumper wire.
Remove the electrical power from the ECM. Expected Result:A short circuit diagnostic code (06) is active when the jumper wire is installed. An open circuit diagnostic code (05) is active when the jumper wire is removed.Results:
OK - The engine harness and the ECM are OK.Repair: Temporarily connect a new engine oil renewal solenoid to the harness, but do not install the new engine oil renewal solenoid. Verify that there are no active diagnostic codes for the solenoid. If there are no active diagnostic codes for the solenoid, permanently install the new solenoid. Clear any logged diagnostic codes.STOP
Not OK - The open circuit diagnostic code (05) remains active with the jumper in place. The open circuit is
