Operating Inspection

Note

•

Perform the following test only as directed.

1. Carry out the “VICS Operation Inspection”. (See 01–03B–57 VICS Operation Inspection.)

•

If not as specified, perform the further inspection for the VICS shutter valve actuator.

2. Disconnect the vacuum hose from the VICS shutter valve actuator.
3. Connect a vacuum pump to the VICS shutter

valve actuator.

4. Apply pressure slowly and inspect the rod

movement of the VICS shutter valve actuator
under the following condition.

•

If not as specified, replace the VICS shutter
valve actuator. (See 01–13B–11 VARIABLE
INERTIA CHARGING SYSTEM (VICS)
SHUTTER VALVE ACTUATOR REMOVAL/
INSTALLATION [FS].)

•

If as specified, but “VICS Operation
Inspection” failed, inspect the vacuum hoses
for proper routing, kinks or leakage.

5. Disconnect the vacuum pump from the VICS shutter valve actuator.
6. Reconnect the vacuum hose to the VICS shutter valve actuator.

VARIABLE INERTIA CHARGING SYSTEM (VICS) SOLENOID VALVE INSPECTION [FS]

A3U011318740W01

Airflow Inspection

Note

•

Perform the following test only as directed.

1. Carry out the “VICS Operation Inspection”. (See 01–03B–57 VICS Operation Inspection.)

•

If not as specified, perform the further inspection for the VICS solenoid valve.

2. Disconnect the battery negative cable.
3. Remove the VICS solenoid valve.
4. Inspect for airflow between each port under the

following condition.

•

If not as specified, replace the VICS solenoid
valve.

•

If as specified but the “VICS Operation
Inspection” failed, carry out the “Circuit Open/
Short Inspection”.
— If there is an open or short circuit, repair

or replace wiring harnesses.

— If there is no open or short circuit, replace

VICS solenoid valve.

Circuit Open/Short Inspection

1. Disconnect the PCM connector. (See 01–40B–7 PCM REMOVAL/INSTALLATION [FS].)
2. Connect the SST (104 Pin Breakout Box) to the

PCM as shown.

3. Tighten the connector attaching screw.

Tightening torque

7.9—10.7 N·m {80—110 kgf·cm, 69.5—95.4

in·lbf}

4. Inspect for an open or short circuit in the following

wiring harnesses by probing the applicable
sensor and SST (104 Pin Breakout Box) terminals
with ohmmeter leads.
Open circuit

•

Power circuit (VICS solenoid valve connector
terminal A and main relay connector terminal D)

•

Control circuit (VICS solenoid valve connector terminal B and PCM connector terminal 19)

Short circuit

•

Power circuit (VICS solenoid valve connector terminal A and main relay connector terminal D to GND)

•

Control circuit (VICS solenoid valve connector terminal B and PCM connector terminal 19 to GND)

5. Reconnect the VICS solenoid valve connector.
6. Reconnect the battery negative cable.
