Lincoln Nautilus: Front End Body Panels / Active Grille Shutter - Overview. Description and Operation
Overview
The active grille shutter system (when equipped) is comprised of the grille shutter assembly and the grille shutter actuator. The active grille shutter system is primarily used to maximize fuel economy by reducing aerodynamic drag on the vehicle. The active grille shutter system is also used to shorten engine warm-up time, increasing engine efficiency and providing heat to the vehicle occupants in a timely manner. The grille shutter actuator receives position commands from the PCM . The active grille shutter system carries out a calibration sequence whenever the engine is started, fully opening and closing the shutters before being positioned in the programmed position as requested by the PCM .
PCM inputs/outputs that may be used for controlling of grille shutters are the:
- ECT sensor
- IAT sensor
- A/C pressure transducer
- APP sensor
- ABS module (through the HS-CAN )
- AAT (ambient air temperature) sensor
- TCT (turbo charge temperature) sensor
- MCT (manifold charge temperature) sensor
- TOT (transmission oil temperature) sensor
- Engine cooling fan motor
- Engine oil temperature

Make sure you did not manually disable the traction control system using the information display controls or the switch. If the stability control and traction control light is still illuminating steadily, have the system serviced by an authorized dealer immediately. Operating your vehicle with the traction co
