Override Parameters
The override parameters screen has multiple overrides. The parameters control various functions on the engine and CEM. These functions and features allow the technician to troubleshoot different engine systems.Cat ET Location
Connect to Cat ET.

Select the Diagnostics tab.
Select the Diagnostic Tests tab.
Select the Override Parameter tab.Override Parameters Listed in the Engine ECM Menu
Engine Exhaust Manifold Bank #1 Flow Balance Valve Solenoid Override
The engine ECM will energize the exhaust balance valve solenoid to on or off. This override will be used when troubleshooting the exhaust balance valve.Fuel Priming Command Override
This override is used to verify that the ARD fuel diverter valve is working properly. The override activates the fuel priming pump. The diverter valve blocks the supply to the ARD head and allows fuel to flow into the engine fuel system.Ether injection Override
This override is used to activate the ether injection solenoid circuit to ensure that the circuit is working properly. The ether canister must be removed during testing of the ether solenoid circuit.Engine Fan Bypass
This override is used to turn ON the engine fan. The override can be used to test the engine fan operation. The engine fan speed is entered as a percent of full speed, this percent allows the user to operate the fan at different speeds.Overrides Parameters Listed in the Engine #1 Aftertreatment Controller Menu
Aftertreatment #1 DEF Dosing Control Module Key Switch Line
This override resets the Diesel Exhaust Fluid Control Unit (DCU) without having to cycle key power to the other ECM's. The reset ensures that the diesel exhaust fluid controller completes a purge cycle, resets any active codes, and shuts down correctly.This test turns off the keyswitch power from the A5:E2 Aftertreatment controller to the DCU for approximately 2 minutes. Once the DCU has successfully powered down and reset, the keyswitch power supply will be turned back on. The DCU will then be operational.Aftertreatment #1 Fuel Injector Heater #1 Override
This override activates the output for the heated nozzle in order to clean the nozzle. The output remains activated for approximately 1 hour. The engine coolant temperature must be greater than 60° C (140° F). The heat cycle will wait for an active regeneration to complete before starting. Once the override has been activated, the heat cycle will automatically start as soon as conditions have been met and cannot be deactivated. It could take up to 8 minutes for conditions to be met for the heat cycle to turn on after being activated by the override. The heat cycle stops if the engine is stopped. The heat cycle continues when the engine is started. Active regenerations will not occur until the heat cycle is complete. This override will be used if a system malfunction was not allowing current to flow to ARD nozzle heater. Lack of current flow could be caused by a blown fuse, broken heater wire, and other damaged components.Aftertreatment Fuel Pump Relay Override
The Engine #1 Aftertreatment Controller will allow the ARD fuel pump to provide fuel to the CEM. This override will be used when pressure testing the ARD fuel pump.ARD Air Pressure Control Position Override
The ECM sends a command to the ARD air valve to open to a specified percentage. The override is used to check the operation of the valve while disassembled.ARD Fuel Flow Diverter Actuator Override
This override is used to cycle the position of the diverter valve on the ARD fuel pump. The diverter valve changes the path of the fuel between the engine and the CEM.DPF Differential Pressure Line Override
This override when Activated, will ignore any fault code from the DPF Delta P sensor. This override will be used when using the DPF crack detection procedure.Overrides Parameters Listed in the Diesel Exhaust Fluid Controller #1 Menu
DEF Coolant Diverter Valve Solenoid Override
The override is used to check the solenoid and diverter valve harness electrically. This override will open the coolant diverter valve which allows coolant to flow through the PETU assembly. This test can be used to verify that the coolant diverter valve is working properly.DEF Dosing Injector Override
This override allows the user to test the electrical circuit for the DEF injector. The override commands the DEF injector to open. This override only operates when there is no engine speed.System Troubleshooting Settings

Aftertreatment #1 Ignition Transformer Primary Override
This override will energize the ARD ignition system to on or off. This override will be used when troubleshooting the ARD ignition system.ARD Regeneration Override
This override will allow the user to perform a regeneration that is similar to the operator using the force switch.Note: This override does not have any enhanced diagnostic ability. All regeneration system troubleshooting should utilize the service tests and not this override.Active Diagnostic Codes
