Terminal No.	Standard
1 and 5	27+3 -2 Ω (when 20°C (68°F))
1 and 5	31±4 Ω (60°C (140°F))

Check that air is discharged from (B) when air is blown into (A).

Connect the battery positive terminal to the terminal No. 5 and the battery negative terminal to the terminal No. 1. Check that air does not come out from (B) when air is blown into (A).

NOTE: The purpose of this inspection is to check the valve movement, and it would be success if a large change of flow can be checked resulting from valve opening/closing. Therefore, it does not indicate a malfunction if a small amount of flow from (B) is detected when the valve is opened.
