4.VERIFY EVAPORATIVE EMISSION LEAK
To continue testing you will need Miller Tool #8404A Evaporative EmissionLeak Detector (EELD).
WARNING: Keep lit cigarettes, sparks, flames, and other ignition sourcesaway from the test area to prevent
the ignition of explosive gases. Keep the test area well ventilated.
NOTE: The fuel tank should have between 20% and 80% of fuel tank capacity to properly test the Evap
system.
Connect the red power lead of the EELD to the battery positive terminal and the black ground lead to battery neg-
ative terminal.
Block the vent hose of the canister if using the service port.
Connect shop air to the EELD.
Set the smoke/air control switch to AIR.
Insert the tester’s AIR supply tip (clear hose) into the appropriate calibration orifice on the tester’s control panel
(based on DTC leak size).
Press the remote smoke/air start button.
Position the red flag on the air flow meter so it is aligned with the indicatorball.
When the calibration is complete, release the remote button. The EELD flowmeter is now calibrated in liters per
minute to the size leak indicated by the DTC set in the PCM.
Install the service port adapter #8404-14 on the vehicle’s service port and block the vent hose of the EVAP Canister
(if equipped) or install the #8404-ADP service adaptor into the filter line.
Connect the Air supply hose from the EELD to the service port (if equipped) or to the #8404-ADP adapter.
Press the remote button to activate AIR flow.
NOTE: Larger volume fuel tanks, lower fuel levels or if the vehicle is equipped with a Flow Management
Valve may indicate high flow and will require 4 to 5 minutes to fill.
Compare the flow meter indicator ball reading to the red flag.
ABOVE the red flag indicates a leak present.
BELOW the red flag indicates a sealed system.
