Phase 1 — Leak Verification 
	- Disconnect the upper vapor tube-to-Evaporative Emission (EVAP) canister 
	purge valve quick connect coupling. For additional information, refer to Section  
	310-00. 
	- Connect the VACUTEC Smoke Machine Fuel Evaporative Emission Tester to the 
	upper EVAP canister purge valve fitting. For additional information, refer to 
	the manufacturer's instructions. 
	- Connect the scan tool and open the EVAP canister purge valve. 
	- Using the scan tool, close the EVAP canister vent solenoid. For additional 
	information, refer to the manufacturer's instructions. 
	- Using the VACUTEC Smoke Machine Fuel Evaporative Emission Tester, pressurize 
	the EVAP system. 
	- Monitor the indicator flag on the VACUTEC Smoke Machine Fuel Evaporative 
	Emission Tester. If the measurement is below the indicator flag, the system 
	has passed the leak test and the test procedure is complete. If the measurement 
	is above the indicator flag, the system has failed the leak test. Proceed to 
	Phase 2. 
Phase 2 — System Leak Check 
	- Introduce smoke from the VACUTEC Smoke Machine Fuel Evaporative Emission 
	Tester into the EVAP system. For additional information, refer to the manufacturer's 
	instructions. 
	- Use the halogen light provided with the VACUTEC Smoke Machine Fuel Evaporative 
	Emission Tester to look for smoke coming from the EVAP system. This would indicate 
	a leak point. 
	- Repair any leaks as necessary. 
	- Repeat the leak test until the system passes.
