Diagnostic Codes Table    
Code and Description     Conditions which Generate this Code     System Response    
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 E540(1) Low Engine Oil Refill Tank Level event code is active.
The ECM may detect a fault in the circuit for the fuel level sensor.
The ECM may detect a fault in the circuit for the oil pressure sensor.
The ECM may detect a fault in the circuit for the oil renewal solenoid.    The ECM adds a controlled amount of engine oil to the fuel by energizing the engine 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".

SchematicTest Step 1. Inspect the Electrical Connectors and the Wiring
Turn the keyswitch to the OFF position.
Illustration 2 g01415758
Location of ECM connectors
Thoroughly inspect the J1/P1 ECM connectors. Inspect all of the other connectors that are in the circuit for the engine oil renewal solenoid. Refer to 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 allen head screw on each of the ECM connectors for the proper torque. Refer to Troubleshooting, "Electrical Connectors - Inspect" for the correct torque values.
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 appear to be 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.
Turn the keyswitch to the ON position.
