Event Code Code Description Comments
E396-1 High Fuel Rail Pressure - Level 1 The ECM detects the following:
The ECM detects fuel rail pressure that is more than the pressure that is required for the operating conditions.
Diagnostic code 262-3 is not active.
Diagnostic code 262-4 is not active.
Diagnostic code 1797-3 is not active.
Diagnostic code 1797-4 is not active.
No diagnostic codes are active for the fuel rail pump.
No diagnostic codes are active for the fuel injectors.
The code is logged.
The engine will be derated until the keyswitch is cycled.
E398-1 Low Fuel Rail Pressure - Level 1 The ECM detects the following:
The ECM determines that the expected fuel rail pressure is lower than the pressure that is requested by the electronic control system.
Diagnostic code 262-3 is not active.
Diagnostic code 262-4 is not active.
Diagnostic code 1797-3 is not active.
Diagnostic code 1797-4 is not active.
No diagnostic codes are active for the fuel rail pump.

Diagnostic Trouble Codes
Use one of the following methods to check for active diagnostic trouble codes:
The electronic service tool
The display on the control panelElectronic Service Tool
Connect the electronic service tool to the diagnostic connector.
Check for active diagnostic trouble codes on the electronic service tool.
Investigate any active codes before continuing with this procedure. Refer to Troubleshooting, "Troubleshooting with a Diagnostic Code". Display on the Control PanelNote: The following procedure is only applicable if the application is equipped with a display on the control panel.
Check the display on the control panel for active diagnostic trouble codes.
Troubleshoot any active codes before continuing with this procedure. Refer to Troubleshooting, "Diagnostic Trouble Codes". Electrical Connections
Check for correct installation of the P1 and P2 connectors on the ECM. Check for correct installation of all other applicable connectors. Refer to Troubleshooting, "Electrical Connectors - Inspect".
Use the electronic service tool to perform a wiggle test.
If necessary, perform any repairs to the connectors or the wiring.
Check if the fault has been eliminated. If the fault is still present, proceed to "Fuel Filters". Fuel Filters
Replace the primary fuel filter and the secondary fuel filter. Refer to the applicable procedure in the Operation and Maintenance Manual.
Check if the fault has been eliminated. If the fault is still present, proceed to "Fuel Rail Pressure Sensor". Fuel Rail Pressure Sensor
With the engine shutdown, use the electronic service tool to check the status of the "Fuel Rail Pressure". After the engine has been shut down for 10 minutes, the "Fuel Rail Pressure (absolute)" must be less than 5,000 kPa (725 psi) (gauge).
If the "Fuel Rail Pressure" on the electronic service tool is less than 5,000 kPa (725 psi), proceed to Step 4.
If the "Fuel Rail Pressure" on the electronic service tool does not fall to less than 5,000 kPa (725 psi) (gauge), the fuel rail pressure sensor may be faulty. Refer to Troubleshooting, "Engine Pressure Sensor Open or Short Circuit - Test".
Use the electronic service tool in order to perform the "Fuel Rail Pressure Test". If the test fails, replace the fuel rail pressure sensor. Refer to Disassembly and Assembly, "Fuel Pressure Sensor - Remove and Install".
If the fault is still present, proceed to "Fuel System". Fuel System
High Fuel Rail Pressure
Use the electronic service tool to monitor the fuel rail pressure. If the fuel rail pressure is abnormal, replace the fuel injection pump. Refer to Disassembly and Assembly, "Fuel Injection Pump - Remove" and Disassembly and Assembly, "Fuel Injection Pump - Install". Low Fuel Rail Pressure
Make sure that the level of fuel in the fuel tank is sufficient. If necessary, fill the fuel tank.
Inspect the high-pressure fuel system for leaks. Rectify any fuel leaks.
Check for the introduction of air in the low-pressure fuel system. Refer to Systems Operation, Testing, and Adjusting, "Air in Fuel - Test". If necessary, rectify the cause of air in the fuel.
Disconnect the outlet from the fuel rail pressure relief valve. Attach a suitable hose to the relief valve and insert the end of the hose in a suitable container. Run the engine for several minutes and check for leakage from the hose. If excessive leakage is identified, replace the fuel rail pressure relief valve. Refer to Disassembly and Assembly, "Fuel Manifold (Rail) - Remove and Install".
If the fault is still present, contact the Technical Communicator at a Caterpillar dealer.
