Powertrain Verification Test VER-6
WARNING:
Keep lit 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 20-80 percent of fuel tank capacity to properly test the EVAP system. To continue testing you will need Miller Evaporative Emission Leak Detector (8404).
- Connect the Red power lead of Evaporative Emission Leak Detector (EELD) to the battery positive terminal and the Black ground lead to battery negative terminal. 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. Install the Service Port Adapter (8404-14) on the vehicle's service port.
- Connect the Air supply hose from the EELD to the service port.
- Press the remote button to activate AIR flow. On vehicles with larger volume fuel tanks, lower fuel levels or if equipped with a Flow Management Valve, this 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. If the indicator ball shows a leak present, perform the smoke test indicated in the previous test and identify the leak and repair. Perform this verification test again when the repair is completed.
- Below the Red flag indicates a sealed system.
- Does the indicator ball indicate a leak is present? If yes, repeat the DTC test that sent you here to identify the leak. Repair as necessary. If no, the test is complete.
