Lincoln Nautilus 2018-2023 Service Manual / Body and Paint / Body and Paint / Front End Body Panels / Active Grille Shutter - Overview. Description and Operation


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

    Traction Control

    How Does Traction Control Work

    If your vehicle begins to slide, the system applies the brakes to individual wheels and, when needed, reduces power at the same time. If the wheels spin when accelerating on slippery or loose surfaces, the system reduces power in order to increase traction.

    Switching Traction Control On and Off

    WARNING: The stability and traction control light illuminates steadily if the system detects a failure. 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
