Operating Inspection

Note

•

Perform the following test only as directed.

1. Carry out the “VTCS Operation Inspection”. (See 01–03B–57 Variable Tumble Control System (VTCS)

Inspection.)

•

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

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

valve actuator.

4. Apply pressure slowly and inspect the rod

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

•

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

•

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

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

VARIABLE TUMBLE CONTROL SYSTEM (VTCS) SOLENOID VALVE INSPECTION [FS]

A3U011318745W01

Simulation Test

1. Carry out the “VTCS Operation Inspection”. (See 01–03B–57 Variable Tumble Control System (VTCS)

Inspection.)

•

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

Airflow Inspection

Note

•

Perform the following test only as directed.

1. Remove the VTCS solenoid valve.
2. Inspect for airflow each port under the following

condition.

•

If as specified, replace the VTCS solenoid
valve.

•

If as specified but the “VTCS Operation
Inspection” is failed, inspect evaporative
hoses for improper routing, kinks or leakage,
and inspect “Circuit Open/Short Inspection”.
— If there is an open or short circuit, repair

or replace wiring harnesses.

— If the above open or short circuit is okay,

replace VTCS solenoid valve.
