DESCRIPTION
This circuit opens and closes the Intake Air Control Valve (IACV) in response to changes in the engine load in order to increase the intake efficiency (ACIS: Acoustic Control Induction System).
When the engine speed is between 0 and 4450 rpm and the throttle valve opening angle is 60 or more, the ECM supplies current to the VSV (ON status), to close the IACV. Under other conditions, the VSV is usually OFF and the IACV is open.

INSPECTION PROCEDURE
1 PERFORM ACTIVE TEST BY INTELLIGENT TESTER (OPERATE VSV FOR ACIS)
OK: Operational noise can be heard.
2 CHECK INTAKE AIR CONTROL VALVE (OPERATION)
OK: Operational noise can be heard.
3 CHECK HARNESS AND CONNECTOR (VSV FOR ACIS - ECM)
Standard resistance : Check for open
Check for short
4 INSPECT FUSE (EFI NO. 2 FUSE)
Standard resistance: Below 1 Ω
5 CHECK HARNESS AND CONNECTOR (VSV FOR ACIS - EFI RELAY)
Standard resistance : Check for open
