ACTIVE GRILLE SHUTTER SYSTEM : Active grille shutter

INFOID:0000000009759580

Active grille shutter is located at front bumper lower opening, and
according to the signal from ECM it operates actuator   to perform
open/close movement of flap   to control the amount of air flow

taken into engine compartment.

ACTIVE GRILLE SHUTTER SYSTEM : System Description

INFOID:0000000009759579

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: 6 km/h (4 MPH)

• S2: Approx. 30 - 140 km/h (19 - 88 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.

SYSTEM

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.

When the vehicle speed is reduced below the specified speed ECM operates active grille shutter to open posi-

tion.

ACTIVE GRILLE SHUTTER OPERATIONAL CONDITIONS 

ECM operates active grille shutter to close position when following all conditions are met.

ECM operates active grille shutter to open position when one of the following conditions is met.
