VARIABLE TUMBLE CONTROL SYSTEM (VTCS) SOLENOID VALVE INSPECTION
Simulation Test
1. Carry out the "VTCS Operation 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 the air flow inspection 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.
