2013 Suzuki SX4 Crossover, Automatic CVT TransSECTION Circuit/System Testing
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.
NOTE:
  • You must start with the Circuit/System Verification before proceeding with Circuit/System Testing.
  • 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 the nitrogen/smoke valve on the control panel to SMOKE.
  2. Command the EVAP vent solenoid closed with a scan tool.
  3. Use the remote switch to introduce smoke into the EVAP system.
  4. Use the J 41413-VLV to open the EVAP service port, if equipped. Or, disconnect the EVAP purge pipe from the purge solenoid. Once smoke is observed, remove the tool, or reconnect the EVAP purge pipe.
    NOTE: Introduce smoke at 15 second intervals while testing the system.
  5. Verify the entire EVAP system with the J 41413-SPT. Smoke should not be observed.
    • If smoke is observed, repair the condition as necessary.
  6. Verify the EVAP system using the EVAP service port. Connect the J 41413-200 nitrogen/smoke supply hose to the EVAP service port. Connect the CH-48096 EVAP Service Port Access Tool between the EVAP purge solenoid and the EVAP purge pipe, if necessary.
  7. Command the EVAP vent solenoid closed with a scan tool.
  8. Use the remote switch to introduce smoke into the EVAP system.
  9. Verify the entire EVAP system with the J 41413-SPT. Smoke should not be observed.
    • If smoke is observed, repair the condition as necessary.
  10. Verify the individual EVAP system components for a leak using the J 41413-300. The EVAP system components should not leak.
    • If a condition is found replace the affected component.
