569-5 Oil Injection 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.
569-6 Oil Renewal Solenoid short to ground The ECM detects a short circuit to ground in the circuit for the oil renewal solenoid.
E2089(1) Oil Renewal System Cannot Operate A 569-5 Oil Injection Solenoid current below normal is active.
or
A 569-6 Oil Renewal Solenoid short to ground is active.
or
The ECM detects a fault in the circuit for the coolant temperature sensor.
or
The ECM detects a fault in the circuit for the fuel level sensor.
or
The ECM detects a fault in the circuit for the oil pressure sensor. 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.
