Diagnostic and Event Codes Table    
Code and Description     Conditions which Generate this Code     System Response    
2271-5
Engine Oil Renewal System Actuation Solenoid : Current Below Normal     The Electronic Control Module (ECM) detects an open circuit and/or a short to the +Battery in the circuit for the oil renewal solenoid.     The code is logged. The oil renewal system is disabled.    
2271-6
Engine Oil Renewal System Actuation Solenoid : Current Above Normal     The ECM detects a short circuit to ground in the circuit for the oil renewal solenoid.    
E2089(1)
Oil Renewal System Cannot Operate - least severe     The oil renewal system cannot operate.    The ECM adds a controlled amount of engine oil to the fuel by energizing the oil renewal solenoid. The engine oil is added to the fuel and burned during combustion. The typical oil change interval may be extended.For further information, refer to Service Manual, RENR2223, "Oil Renewal System".

Troubleshooting Test Steps    Values    Results    
1. Inspect the Electrical Connectors and the Wiring
A. Remove the electrical power from the engine ECM.
B. Thoroughly inspect the J1/P1 and J2/P2 ECM connectors. Inspect all of the other connectors that are in the circuit for the oil renewal solenoid. Refer to Troubleshooting, "Electrical Connectors - Inspect".
C. Perform a 45 N (10 lb) pull test on each of the wires in the ECM connector that are associated with the circuit.
D. Check the allen head screw on each of the ECM connectors for the proper torque. Refer to Troubleshooting, "Electrical Connectors - Inspect" for the correct torque values.
E. Check the harness and the wiring for abrasion and for pinch points.
    Inspect Connectors and Wiring    
Results: The harness and wiring appear to be OK.
Proceed to Test Step 2.
Results: 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 coupled.
Verify that the repair eliminates the problem.
   
2. Check for Active Diagnostic Codes
A. Connect Caterpillar Electronic Technician (ET) to the service tool connector.
B. Restore the electrical power to the engine ECM.
C. 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.
D. Select diagnostic tests from Cat ET.
E. Select the "Override Parameters" screen on Cat ET.
F. Activate the override for the oil renewal solenoid.
G. 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.
H. Disable the override for the oil renewal solenoid.
I. Remove the electrical power from the engine ECM.
J. Determine if the problem is related to an open circuit diagnostic code -5 or a short circuit diagnostic code -6.
    Active Code    
Results: No diagnostic codes are active.
Repair: There does not appear to be a problem with the oil renewal solenoid at this time. The problem may have been related to an intermittent electrical problem in the harness or in a connector. If an intermittent electrical problem is suspected, carefully inspect the connectors and wiring. Refer to Troubleshooting, "Electrical Connectors - Inspect" for details.
Results: A short circuit diagnostic code -6 is active at this time.
Proceed to Test Step 3.
Result: An open circuit diagnostic code -5 is active at this time.
Proceed to Test Step 4.

Troubleshooting Test Steps    Values    Results    
3. Disconnect the Connector for the Oil Renewal Solenoid in order to Create an Open Circuit
A. Disconnect the connector for the oil renewal solenoid.
B. Restore the electrical power to the engine ECM.
C. 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.
D. Select diagnostic tests from Cat ET.
E. Select the "Override Parameters" screen on Cat ET.
F. Activate the override for the oil renewal solenoid.
G. 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.
H. Disable the override for the oil renewal solenoid.
    Open Circuit    
Results: A short circuit diagnostic code -6 was active before disconnecting the connector. An open circuit diagnostic code -5 became active after disconnecting the connector.
Repair: Temporarily connect a new oil renewal solenoid to the harness, but do not install the new solenoid. Verify that there are no active diagnostic codes for the oil renewal solenoid. If there are no active diagnostic codes for the solenoid, permanently install the new solenoid. Clear any logged diagnostic codes.
Results: A short circuit diagnostic code -6 remains active when the connector for the oil renewal solenoid is disconnected. There is a short circuit between the harness connector for the oil renewal solenoid and the ECM.
Proceed to Test Step 4.

4. Create an Open at the ECM:
A. Disconnect the J1/P1 ECM connector.
B. Fabricate a jumper wire that is long enough to create a short between the ECM connector and engine ground. Crimp a connector socket to one end of the jumper wire.
C. Remove the wire from terminal location P1-20 (oil renewal solenoid) at the ECM connector. Install the jumper wire into this terminal location.
D. Connect the J1/P1 ECM connector.
E. Create an open at the ECM:
a. Restore the electrical power to the engine ECM.
Ensure that an open circuit c
