4. Use the SMOKE to find the leak.
5. Repair and re-test until no more leaks are found.
DIAGNOSIS:
EVAP Leaks:
1. Verify that a leak is present using the Leak Decay Test with the Internal Pump or Air/Inert Gas.
2. If the vehicle has an EVAP service port (Green Cap) then remove the schrader valve with the removal/installer tool that is supplied with the kit. (NOTE: The schrader valve
has left-hand threads. Turn the valve clockwise to remove) Attach the service port adapter that is supplied with the kit to the EVAP service port. Attach the EVAP service
port adapter hose to the smoke hose cone.
If the vehicle does not have an EVAP service port, then one of the EVAP vacuum hose will have to be disconnected. One hose will have to be capped with the plugs that is
supplied with the kit. Attach the other hose to the smoke hose cone.
3. Use a scan tool to close the EVAP canister vent solenoid.
4. Pressurize the system until the gauge reaches 0.5 PSI EVAP CHECK.
5. Cap the pressure in the system by turning the flow meter control knob clockwise until the flow meter is closed.
6. Observe the pressure reading on the pressure gauge. If the gauge does not lose pressure then there are no leaks present. If the gauge does lose pressure then a leak
exists. The flow meter will indicate the size of the leak.
7. To find the leak, press the SMOKE button to start the 5 minute smoke cycle and open the flow meter control knob counter-clockwise.
8. Remove the fuel cap. When smoke is present exiting the fuel tank, re-install the fuel cap.
9. While the smoke is still being pumped into the vehicle, use the flashlight to locate the leak(s).
10. Repair and re-test until no more leaks are found.
Intake Leaks:
1. Disconnect the intake air duct from the air filter box.
2. Insert the cone adapter that is supplied with the kit into the intake duct.
3. Attach the cone adapter to the smoke hose cone.
4. Pressurize the system by pressing the PUMP button or use external Air/Inert Gas.
5. Press the SMOKE button.
6. Use the flashlight to locate any leaks.
NOTE:
Some vacuum hoses may need to be capped to find small or to isolate leaks.
NOTE:
Some intakes may not be 100 percent sealed by design.
7. Repair and re-test until no more leaks are found.
Vacuum Lines and Vacuum Component Leaks:
1. Disconnect the vacuum line for the component or vacuum circuit that is to be tested.
2. Insert the smoke hose cone to the vacuum line.
3. Pressurize the component or circuit by pressing the PUMP button or use external Air/Inert Gas.
4. Press the SMOKE button.
5. Use the flashlight to locate any leaks.
Note:
The air filter box may need to be sealed so that the circuit being tested does not back flow into the air filter box.
Note:
Some vacuum hoses may need to be capped to find small or to isolate leaks.
Note:
Some vacuum components may be not be 100 percent sealed by design.
6. Repair and re-test until no more leaks are found.
Exhaust Leaks:
1. Insert the cone adapter that is supplied with the kit into the tail pipe of the exhaust.
NOTE:
If the vehicle has dual exhaust, use the cap plugs to seal the other tail pipe.
2. Pressurize the exhaust system by pressing the PUMP button or use external Air/Inert Gas.
3. Press the SMOKE button.
NOTE:
Some smoke may be consumed by a hot catalytic converter.
4. Use the flashlight to locate any leaks.
NOTE:
Exhaust leaks are easier to find when the exhaust system is at ambient temperature.
5. Repair and re-test until no more leaks are found.
Under the Dashboard Leaks:
1. Disconnect the vacuum line for the component or vacuum circuit that is to be tested.
2. Insert the smoke hose cone into the vacuum line.
3. Pressurize the circuit by pressing the PUMP button or use external Air/Inert Gas.
4. Press the SMOKE button.
5. Check the pressure gauge and the flow meter while cycling through the climate controls.
6. Changes in the pressure gauge or the flow meter readings will indicate which system is leaking.
7. Set the climate control to the system that is leaking.
8. Use the flashlight to locate any leaks.
9. Repair and re-test until no more leaks are found.
NOTE:
The central locking can be checked in the same manner. Activate the control solenoids while smoke is being pumped into the system.
MAINTENANCE:
Cleaning the Flow Meter:
1. Disconnect the unit from the power supply.
2. Disconnect the unit from external Air/Inert Gas source.
3. Remove the screw from the bottom of the flow meter bracket.
