(a) Remove the VSV for ACM.
(b) Check operation of the VSV for ACM when positive
battery voltage is applied to the terminals of the VSV for
ACM connector.
Positive battery voltage is not applied:
The air from pipe G is flowing out through pipes E
and H.
Positive battery voltage is applied:
The air from pipe F is flowing out through pipes E
and H.
(c) Reinstall the VSV for ACM.

OK
(a) Disconnect the vacuum hose from the front engine
mount insulator.
(b) Using a vacuum pump, apply vacuum of 80 kPa (600
mmHg, 25 in.Hg) and wait for 1 minute.
(c) Check that there is no change in the needle movement
of the vacuum pump gauge.
(d) Check that there is no fluid leakage caused by a break in
the diaphragm.
OK:
Vacuum pressure exists.
(e) Reconnect the vacuum hose.
