Scan Tool Output Control	Additional Menu Selection(s)	Description
Cylinder Power Balance	Fuel System	Disables each fuel injector. The device control will time out after 5 minutes unless changed or cancelled by the scan tool. Device Control can be changed at any engine or vehicle speed.
EGR Solenoid	Engine Output Controls	Activates the exhaust gas recirculation (EGR) solenoid ON or OFF. The EGR position is limited to 30 percent duty cycle, which is a fully open valve. The device control is limited to 10 seconds ON, with a 10 second OFF cooling time.
Fuel Pressure Control	Fuel System	Activates the Fuel Pressure Regulator in 10 percent increments from 0-100 percent. The Device Control will not change unless changed or cancelled by the scan tool.
Fuel Pump	Engine Output Controls	Activates the fuel transfer pump ON or OFF. The Device Control will not change unless changed or cancelled by the scan tool.
Glow Plug	Engine Output Controls	Activates the Glow Plug Controller ON or OFF. The Device Control will be aborted after 12 seconds for the first activation, and after 5 seconds for every other activation. Device control is inhibited if the engine is running.
Malfunction Indicator Lamp	Engine Output Controls	Activates the malfunction indicator lamp (MIL). The MIL will remain illuminated until cancelled by the scan tool.
RPM Control	Fuel System	Adjusts the engine speed in 25, 100, or 500 RPM increments. The Device Control will not change unless changed or cancelled by the scan tool.
TC Vane Sensor	Engine Output Controls	Adjusts the turbocharger vane position in 10 percent increments from 0-100 percent. The device control will be aborted if engine speed is above idle or the coolant temperature is too cold.
TC Vane Solenoid	Engine Output Controls	Cycles the turbocharger vane position solenoid to 100 percent boost and back to 0 percent boost. The vane position sensor is not accurate during this output control. The device control is limited to engine speeds less than 1500 RPM.
