RENR5042-02 81 Troubleshooting Section i02277367 E096 High Fuel Pressure E360-2 (Derate) The engine power will be derated. SMCS Code: 1250-038-HQ E360-3 (Shutdown) Conditions Which Generate This Code: The engine will shut down. The Electronic Control Module (ECM) detects a problem with the engine’s fuel pressure. Information on default settings and ranges for this event code can be found in Troubleshooting, “Event Codes”. Troubleshooting: There may be a problem with the engine’s lubrication system. System Response: Check the Engine’s Lubrication System The event code will be logged. A. Check the engine oil level.
If the oil level is below the oil pump’s supply tube, the oil pump will not have the ability to supply enough lubrication to the engine components. If the engine oil level is low, add engine oil in order to obtain the correct engine oil level. Possible Performance Effect: E096 (Warning) None Check the Fuel System B. Check the following problems that may occur to the engine oil pump: A. Verify that the check valve in the fuel manifold is operating correctly. Check for damage or for dirt in the check valve. a. Air leakage in the supply side of the oil pump will also cause cavitation and loss of oil pressure. Check the supply side of the oil pump and make necessary repairs. B.
Check the return line from the check valve to the fuel tank for damage or collapse. b. Oil pump gears that have too much wear will cause a reduction in oil pressure. Repair the engine oil pump. Results: OK A problem was found in either the check valve or in the return line to the fuel tank. c. If the engine is equipped with a scavenge pump, the scavenge pump may not be supplying oil to the main engine oil pump. Repair: Replace all suspect parts. STOP. C. The inlet screen of the oil suction tube for the engine oil pump can have a restriction. This restriction will cause cavitation and a loss of engine oil pressure.
Check the inlet screen on the oil pickup tube and remove any material that may be restricting engine oil flow. Low engine oil pressure may also be the result of the oil pickup tube that is drawing in air. Check the joints of the oil pickup tube for cracks or a damaged O-ring seal. i02274316 E360 Low Engine Oil Pressure SMCS Code: 1348-038-LP Conditions Which Generate This Code: The Electronic Control Module (ECM) detects a problem with the engine’s oil pressure. Information on default settings and ranges for this event can be found in Troubleshooting, “Event Codes”. D. If the engine oil bypass valves are held in the open position, a reduction in the oil pressure can be the result.
This may be due to debris in the engine oil. If the engine oil bypass valves are stuck in the open position, remove each engine oil bypass valve and clean each bypass valve in order to correct this problem. You must also clean each bypass valve bore. System Response: The event code will be logged. Possible Performance Effect: E. Engine oil that is contaminated with fuel or coolant will cause low engine oil pressure. High engine oil level in the crankcase can be an indication of contamination. E360-1 (Warning) None
