TEST ACTION APPLICABILITY
3 To continue testing you will need Miller Tool #8404 Evaporative Emission Leak
Detector (EELD).
WARNING: Keep lighted cigarettes, sparks, flames, and other ignition
sources away 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 negative terminal.
NOTE: See Charts and Graph support material EELD Calibration Setup for
an example.
Block the vent hose of the EVAP Canister.
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 indicator ball.
When the calibration is complete, release the remote button. The EELD is now
calibrated the flow meter 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 (if equipped) or
install the #8404-ADP service adapter in the NVLD filter line.
Connect the Air supply hose from the EELD to the service port.
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.
