Powertrain Verification Test VER-6

NOTE: If replacing Powertrain Control Module (PCM), the correct vehicle mileage and Vehicle Identification Number (VIN) must be programmed into PCM to prevent Diagnostic Trouble Codes (DTC) from being stored in Controller Anti-Lock Brake System (CAB) and Supplemental Restraint System (SRS) module. If replacing PCM and vehicle is equipped with a Smart Key Immobilizer Module (SKIM), secret key data must also be updated to enable engine starting.

Inspect vehicle to ensure all engine components are connected. Reassemble and reconnect components as necessary.

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.

Install Miller EVAP Emission Leak Detector (EELD) Tool (8404). 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 has 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. Connect the Air supply hose from the EELD to the service port.

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 4-5 minutes to fill.

Press the remote button to activate AIR flow. 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. Does the indicator bowl indicate a leak is present? If no, test is complete. If yes, go to next step.
Remove the Air supply hose from the service port. Connect the Smoke supply tip (Black hose) to the service port. Set the Smoke/Air control switch to Smoke. The flow meter indicator ball will not move at this point. Press the remote Smoke/Air Start button. Ensure that smoke has filled the EVAP system by continuing to press the remote Smoke/Air Start button, remove the vehicle fuel cap, and wait for the smoke to exit. Once smoke is indicated, reinstall the fuel cap. For optimal performance, introduce smoke into the system for an additional 60 seconds, continue introducing smoke at 15 second intervals, as necessary. While still holding the remote Smoke/Air Start button, use the White Light (8404-CLL) to follow the EVAP system path, and look for the source of the leak indicated by exiting smoke. If a leak is concealed from view, such as on top of fuel tank, release the remote Smoke/Air Start button, and use the Ultraviolet Black Light (8404-UVL) and the Yellow Goggles (8404-20) to look for residual traces of dye left behind by the smoke. The exiting smoke deposits a residual fluid that is either Bright Green or Bright Yellow when viewed with UVL. Carefully inspect the vent side of the EVAP Canister. Due to the filtering system in the canister, the smoke or dye may or may not be visible. Introducing smoke into the filtered side of the canister may assist in locating the leak. Was a leak found? If yes, repair or replace the leaking component as necessary. If no, repair is complete.
