13. Plug outlet nozzle with finger or the rubber plug.
The evaporative emission system should now be sealed and ready to be tested.
CAUTION: The ventilation nozzle of EVAP leak check module must be blocked securely. The reason for this is that the EVAP system in
its design cannot be sealed completely even though the EVAP canister vent valve and the EVAP canister purge valve are both closed
because the leak check module internally opens to atmosphere through the leak detection pump. For this reason, if the ventilation nozzle
of the leak check module is not blocked completely, nitrogen gas will leak through it possibly resulting in a diagnostic error of EVAP leak.
14. Press and release the remote switch to activate the nitrogen flow and fill the system. Watch the flowmeter s indicator until it stabilizes.
NOTE:
^
The remote switch operates in a push ON, push OFF manner.
^
Larger volume fuel tanks and/or those with lower fuel levels may require several minutes to fill with nitrogen.
15. Compare the stable floating indicator position to the red flag as follows.
a. If indicator floats above the red flag, the result is UNACCEPTABLE. Locate and repair a leak referring to EVAP Leak Check System Smoke
Test.
