Circuit/System Verification

WARNING: This page is about a different car, the 2007 Suzuki XL7. However, it is still accessible from the selected car via links, so may be relevant.

WARNING:

Place a dry chemical (Class B) fire extinguisher near the area before performing a Fuel Tank Leak Check. Before removing the fuel tank for a suspected leak, make sure that the fuel pipes or the tubes are not leaking onto the tank. Once removed, make sure that the fuel is not leaking around the fuel sender O-ring. Failure to follow these precautions may result in personal injury.

Verify that the fuel tank and the fuel pipes are not damage or leaking.
- if you located a condition, repair as necessary.
Ignition ON, command the fuel pump relay ON with a scan tool. Verify that the fuel pipes are not leaking.
- if you located a condition, repair as necessary.
  NOTE:
  Refer to the J 41413-200 Evaporative Emissions System Tester (EEST) operation manual for detailed instructions.
Ignition OFF, install the J 41413-200 and the GE-41415-50 to the fuel filler pipe.
Command the EVAP vent solenoid closed with a scan tool.
Turn the nitrogen/smoke valve to Nitrogen and verify that there is no liquid fuel leak while the system is under pressure.
- if a leak is located, repair as necessary.
  NOTE:
  It may be necessary to partially lower the fuel tank.
Using the J 41413-200 introduce smoke into the EVAP system. Verify that there are no vapor leaks in any of the following locations:
- The fuel tank, the fill limiter vent valve, the pressure relief valve, and the grade vent valves
- The fuel sender housing, the fuel sender seal, the fuel pipe, and the EVAP pipes
- The fuel tank pressure (FTP) sensor seal
- The fuel fill pipe and hose
  - if a leak is observed, repair as necessary.
