ACIS Control Circuit [04/2013 - 08/2015]: Description
This circuit opens and closes the intake air control valve assembly (built into intake air surge tank assembly) in response to changes in the engine load in order to increase the intake efficiency using the acoustic control induction system.
When the engine speed is between 1900 and 4200 rpm and the throttle valve opening angle is 30° or more, the ECM supplies current to the actuator (on status), to close the intake air control valve assembly. Under other conditions, the intake air control valve assembly is open.
