ACTIVE GRILLE SHUTTER SYSTEM : System Description
INFOID:0000000010479946
While driving, the active grille shutter system closes shutter to reduce air flow to engine compartment for the
purpose of reducing aerodynamic drag, and as a result, improves the vehicle's fuel efficiency.
ECM controls active grille shutter system by detecting vehicle status through respective modules and sensors.
Active grille shutter actuator is equipped with self-diagnosis function. When it detects malfunction, transmits
diagnosis signal to ECM and ECM records active grille shutter malfunction.
BASIC MOVEMENTS
• S1: Approximately 30 - 160 km/h (19 - 100 MPH)
• *1: Shutter initial position learning.
• *2: Judgement of high vehicle speed.
• *3: Judgement of low vehicle speed.
DESCRIPTION OF MOVEMENTS
Active grille shutter is fully open when the vehicle stops or the ignition switch is turned OFF.
ECM operates the shutter to close position in order to perform shutter's initial position learning when the igni-
tion switch is turned ON and the vehicle reaches the specified speed for the first time. At the end of initial posi-
tion leaning ECM operates shutter to open position. (The initial position learning is performed every time when
ignition switch is turned OFF
→
ON.)
While driving, after the initial position learning ends, ECM operates the active grille shutter to close position
when the operational conditions of active grille shutter are met.
While driving at high speed, ECM operates the shutter to open position when the vehicle reaches the specified
speed in order to prevent the shutter from shutting up by wind resistance.
