| Cooling Fan | Cooling Fan Speed Enable; Cooling Fan Speed |
| Cooling Fan Relay 1 | Cooling Fan Speed Enable; Cooling Fan Speed |
| Cooling Fan Relay 2 | Cooling Fan Speed Enable; Cooling Fan Speed |
| Cooling Fan Relay 3 | Cooling Fan Speed Enable; Cooling Fan Speed |
| Crank Case Ventilation Heater | Activate heater for crankcase ventilation Crank Case Ventilation Heater ON |
| Cylinder Power Balance | Fuel Injector Enable; Fuel Injector ON |
| EGR Cooler Bypass Valve | Activate bypass valve to EGR cooler. Bypass valve to EGR cooler ON. |
| EGR Valve | This function opens or closes the exhaust gas recirculation (EGR) solenoid. The EGR solenoid increases or decreases in 10 percent increments. The device control will not change unless changed or cancelled by the scan tool. |
| Engine Speed | This function adjusts engine speed in steps of 25, 100 or 500 rpm between 600-1 500 rpm. The Device Control will not change unless changed or cancelled by the scan tool. |
