Connect the J 41413-200 nitrogen/smoke supply hose and vehicle fuel fill cap to the GE-41415- 4. Command the EVAP canister vent solenoid valve open with a scan tool. 5. Compare the fuel tank pressure sensor parameter with a scan tool to theJ 41413-200 Is the difference between the two gauges less than the 1 in H2O Go to Step 6 Go to Step 12 6 1. Seal the EVAP system using the EVAP Purge/Seal function with a scan tool. 2. Turn the nitrogen/smoke valve on the J 41413- 200 control panel to NITROGEN. 3. Use the J 41413-200 to pressurize the EVAP system to the first specified value. Is the fuel tank pressure sensor parameter more than the 13 in H2O 5 in H2O Go to Step 7 Go to Step 12 7 1. Stop introducing nitrogen into the EVAP system with the remote switch. 2. Increase the EVAP canister purge solenoid valve to 100 percent. 1 in H2O
