Ford Ecosport: Front End Body Panels / Description and Operation - Active Grille Shutter - Overview
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
