Condition

Specified Condition

1 - 2

20°C (68°F)

23 to 26 Ω

1 - VSV body ground

Always

10 kΩ or higher

2 - VSV body ground

10 kΩ or higher

If the result is not as specified, replace the purge VSV.

(b) Check the operation of the purge VSV.

(1) Check that air does not flow from port F when air is applied to port E.

(2) Apply battery voltage to the connector, and check the VSV operation.

OK:
