Override Parameters
The override parameters screen has multiple overrides. The parameters control various functions on the engine and the aftertreatment. These functions and features allow the technician to troubleshoot different engine systems.In the electronic service tool, select the engine ECM or the Diesel Exhaust Fluid Controller (DCU) as appropriate for the required override.Override Parameters Listed in the Engine ECM Menu
Aftertreatment #1 Intake NOx Level Sensor Power Supply Override
This override can be used during troubleshooting to reset the SCR intake NOx sensor without having to cycle key power to the Engine ECM.Aftertreatment #1 Outlet #1 NOx Level Sensor Power Supply Override
This override can be used during troubleshooting to reset the SCR Outlet NOx Sensor without having to cycle key power to the Engine ECM.Aftertreatment #1 DEF Dosing Control Module Key Switch Line
This override resets the Dosing Control Unit (DCU) without having to cycle key power to the other ECM's. The reset ensures that the DCU completes a purge cycle, resets any active codes, and shuts down correctly.This test turns off the key switch power from the engine ECM to the DCU for approximately 2 minutes. Once the DCU has successfully powered down and reset, the key switch power supply will be turned back on. The DCU will then be operational.Engine Fan Bypass
This override is used to turn ON the engine fan, if equipped. The override can be used to test the engine fan operation. The engine fan speed is entered as a percent of full speed, allowing the user to operate the fan at different speeds.Engine Fuel Supply Lift Pump Relay Override
This override is used to energize the Electric Fuel Lift Pump (EFLP) relay. The override can be used to test the EFLP relay only when engine speed is zero. The EFLP relay is switched to either ON or OFF.Engine Shutdown Lamp
