3. Connect a hand vacuum pump to solenoid valve A and carry 

out the following inspections.

(1) Even if the hand pump is operated with no other 

operation, no negative pressure develops.

(2) Negative pressure does not develop when battery 

voltage is applied to solenoid valve A. Negative pressure 
is maintained when the vacuum hose of solenoid valve B 
is blocked by bending.

(3) When battery voltage is applied to solenoids A and B, 

negative pressure is maintained.

4. Connect the hand vacuum pump to solenoid valve B. Apply 

negative pressure and carry out the following inspections.

(1) With no change, negative pressure is maintained.
(2) When battery voltage is applied to solenoid valve B, the 

vacuum shuts off.

(3) When battery voltage is applied to solenoid valve A, the 

vacuum shuts off.

5. Measure the resistance of the solenoid valves.
