VIAS Control Solenoid Valve (Except Murano & Pathfinder)

1. With CONSULT-II
   
   Disconnect vacuum hoses from VIAS control solenoid valve. Turn ignition on. On CONSULT-II from ACTIVE TEST mode, select VIAS SOL VALVE. Using CONSULT-II, command valve On and Off. Using an auxiliary length of vacuum hose connected to vacuum port " A" blow through valve under specified conditions. See CHECKING VIAS CONTROL SOLENOID VALVE WITH CONSULT-II  table. See Fig 1. If valve does not test as specified, replace VIAS control solenoid valve.
   CHECKING VIAS CONTROL SOLENOID VALVE WITH CONSULT-II
   
   

   VIAS Valve Condition	Air Passage Continuity Between A & B	Air Passage Continuity Between A & C
   ON	Yes	No
   OFF	No	Yes

2. Without CONSULT-II
   
   Disconnect vacuum hoses from VIAS control solenoid valve. Turn ignition on. Using 2 jumper wires, jumper VIAS control solenoid valve pin No. 1 to battery voltage and pin No. 2 to ground. Using an auxiliary length of vacuum hose connected to vacuum port "A", blow through valve under specified conditions. When voltage is applied to solenoid, air should flow between vacuum ports "A" and "B", and air should not flow between vacuum ports "A" and "C". When voltage is removed from valve, air should flow between vacuum ports "A" and "C", and air should not flow between vacuum ports "A" and "B". See Fig 1. If valve does not test as specified, replace VIAS control solenoid valve.
