(b) Remove the 4 bolts, clip and canister.
INSPECTION
1. INSPECT CANISTER
(a) Visually check the canister for cracks or damage.
If cracks or damage is found, replace the canister.
(b) Check the canister operation.
(1) While holding the purge port closed, blow air
0.39 kPa (4.0 kgf/cm
2, 3 mmHg) into the vent
port, and check that air flows from the air inlet
port.
If the result is not as specified, replace the
canister.
(2) While holding the air inlet port closed, blow air
0.39 kPa (4.0 kgf/cm
2, 3 mmHg) into the vent
port, and check that air flows from the purge
port.
If the result is not as specified, replace the
canister.
(3) While holding the air inlet port closed, apply
vacuum 3.43 kPa (35.0 kgf/cm
2, 25.7 mmHg)
to the vent port, and check that air is sucked
into the purge port.

(c) Check the air tightness.
(1) While holding the vent and air inlet ports
closed, apply vacuum 3.43 kPa (35.0 kgf/cm
2,
25.7 mmHg) to the purge port, and check that
the vacuum is maintained for 1 minute.
If the result is not as specified, replace the
canister.
(d) Check the diaphragm.
(1) Remove the air hose between ports A and B.
(2) While holding the vent, purge and air inlet ports
closed, apply vacuum 1.42 kPa (14.5 kgf/cm
2,
10.6 mmHg) to port A, and check that air is not
sucked into port B.
(3) While holding the vent, purge and air inlet ports
closed, apply vacuum 1.42 kPa (14.5 kgf/cm
2,
10.6 mmHg) to port A, and measure how long it
takes for the vacuum to drop.
Vacuum drop time:
10 seconds or more
If the result is not as specified, replace the
canister.
(e) Check the leak detection pump.
(1) Check that air flows from port A to port B and
C.
If the result is not as specified, replace the
canister.
(2) Connect the positive (+) lead of the battery to
terminal 7 and the negative (-) lead to terminal
6.
(3) Check that the valve is closed.
If the result is not as specified, replace the
canister.
(4) Install the canister pump module.
