IMPORTANT: Ensure that the vehicle underbody temperature is similar to the ambient temperature and allow the surrounding air to stabilize before starting the diagnostic procedure. The system flow will be less with higher temperatures.
  1. Turn OFF the ignition.
  2. Connect the J 41413-200  Evaporative Emissions System Tester (EEST) power supply clips to a known good 12-volt source. See Special Tools .
  3. Install the GE-41415-50  Fuel Tank Cap Adapter to the fuel fill pipe. See Special Tools .
  4. Connect the J 41413-200  Nitrogen/Smoke Supply Hose to the GE-41415-50  . See Special Tools .
  5. Turn ON the ignition, with the engine OFF.
  6. Turn the nitrogen/smoke valve on the J 41413-200  control panel to SMOKE. See Special Tools .
  7. Command the EVAP vent solenoid closed.
  8. Use the remote switch to introduce smoke into the EVAP system.
  9. Use the J 41413-VLV EVAP Port Vent Fitting tool to open the EVAP service port.
  10. Remove the J 41413-VLV once the smoke is observed.
  11. Continue to introduce smoke into the EVAP system for an additional 60 seconds.
  12. Inspect the entire EVAP system for exiting smoke with the J 41413-SPT  High Intensity White Light. See Special Tools .
  13. Continue to introduce smoke at 15-second intervals until the leak source has been located.
Did you locate and repair a leak source?		 - Go to Step 5  Go to Diagnostic Aids

IMPORTANT: Larger volume fuel tanks and/or those with lower fuel levels may require several minutes for the floating indicator to stabilize.
  1. Turn the nitrogen/smoke valve to NITROGEN.
  2. Connect the nitrogen/smoke hose to the 0.5 mm (0.020 in) test orifice on the bottom-front of the J 41413-200  . See Special Tools .
  3. Use the remote switch to activate the J 41413-200  . See Special Tools .
  4. Align the red flag on the flow meter with the floating indicator. Use the remote switch to de-activate the J 41413-200  . See Special Tools .
  5. Install the GE-41415-50  to the fuel fill pipe. See Special Tools .
  6. Remove the nitrogen/smoke hose from the test orifice and install the hose onto the GE-41415-50  . See Special Tools .
  7. Turn ON the ignition, with the engine OFF.
  8. Use the remote switch to introduce nitrogen and fill the EVAP system until the floating indicator stabilizes.
  9. Compare the flow meter stable floating indicator position to the red flag.
Is the floating indicator below the red flag?		 - Go to Step 6  Go to Step 2 
6  Observe the Capture Info with a scan tool.
Are there any DTCs that have not been diagnosed?		 - Go to Diagnostic Trouble Code (DTC) List System OK
