VARIABLE TUMBLE CONTROL SYSTEM (VTCS) SHUTTER VALVE ACTUATOR INSPECTION

NOTE: Perform the following test only when directed.

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







3. Apply vacuum 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 VARIABLE TUMBLE CONTROL SYSTEM (VTCS) SHUTTER VALVE ACTUATOR REMOVAL INSTALLATION.)
- If as specified but the Simulation Test fails, inspect for the following:
Vacuum hose improper routing, kinks or leakage.
