Engine Exhaust Manifold Bank #1 Flow Balance Valve Solenoid Override
This override will energize the exhaust balance valve solenoid to on or off. This override will be used when troubleshooting the exhaust balance valve.Aftertreatment #1 Fuel Injector Heater 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.Engine Fan Bypass
