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

A3U011320153W02

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.
