EXT-12
< SYSTEM DESCRIPTION >
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 shutte r 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 a ll conditions are met.
ECM operates active grille shutter to open positi on when one of the following conditions is met.
