DESCRIPTION
The air cleaner is equipped with two inlets, one of which is opened or closed by the Air Intake Control Valve (AICV). This system reduces intake noise and increases engine power at low-to-high engine speed range.
When the engine is operating in the low-to-mid speed range, this control operates the AICV to close one of the air cleaner inlets. When the engine speed is more than 3600 rpm and the opening angle of the throttle valve is more than 60°, the ECM activates the VSV and opens the AICV.

INSPECTION PROCEDURE
1 PERFORM ACTIVE TEST BY INTELLIGENT TESTER (VSV FOR AICV)
(a) Turn the ignition switch to the ON position and turn the intelligent tester on.
(b) Select the following menu items: DIAGNOSIS / ENHANCED OBD II / ACTIVE TEST / INTAKE CTL VSV1 and operate the VSV for AICV.
(c) Check the operation of the VSV when the VSV is operated by the intelligent tester.
Standard
2 CHECK VSV (FOR AICV)
(a) Inspect the intake air control valve assembly (See page IT-8).
3 CHECK HARNESS AND CONNECTOR (VSV FOR AICV - ECM)
(a) Check the wire harness between the VSV for AICV connector and the ECM connector.
Standard resistance:
(4) Reconnect the ECM connector.
4 INSPECT FUSE (EFI NO. 2 FUSE)
(a) Check the EFI No. 2 fuse.
(1) Remove the EFI No. 2 fuse from the engine room junction block.
(2) Measure the EFI No. 2 fuse resistance.
Standard resistance: Below 1 Ω
(3) Reinstall the EFI No. 2 fuse.
5 CHECK HARNESS AND CONNECTOR (VSV FOR AICV - EFI RELAY)
(a) Check the wire harness between the VSV for AICV and the EFI relay.
(1) Remove the EFI relay from the engine room junction block.
(2) Measure the resistance according to the value(s) in the table below
Standard resistance :
(3) Reconnect the VSV for AICV connector.
(4) Reinstall the EFI relay.
6 INSPECT VACUUM TANK
(a) Inspect the vacuum tank (See page IT-6).

Initialization
1. RESET
Reset the power slide door system:
The power slide door ECU records the fully open
position of the power slide door in its memory and
the power slide door fully opens and closes based
on this memory. The power slide door cannot
operate without this memory. In the case wh ...
