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.
- Verify the following conditions do not exist in the EVAP system:
- Loose, incorrect, missing, or damaged fuel fill cap
- Loose, missing, or damaged service port schrader valve (if equipped)
- Loose or damaged fuel tank pressure (FTP) sensor.
- A damaged EVAP purge solenoid
- Disconnected, incorrectly routed, kinked, or damaged EVAP pipes and hoses
- A damaged EVAP vent valve or EVAP canister
- If you find any of the above conditions, repair as necessary.NOTE: Refer to the J 41413-200 operation manual for detailed instructions.
- If you find any of the above conditions, repair as necessary.
- Remove the fuel fill cap. Connect the GE-41415-50 to the fuel tank filler neck. Connect the J 41413-200 to the GE- 41415-50.
- Calibrate the J 41413-200 Flow Meter to the correct leak orifice for the vehicle.
- Command the EVAP vent solenoid closed with a scan tool.NOTE: Larger volume fuel tanks and/or those with lower fuel levels may require several minutes for the floating indicator to stabilize.
- Activate the J 41413-200 and compare the flow meter's stable floating indicator position to the red flag. The floating indicator should be below the red flag.
- If the floating indicator is above the red flag, test for a leak in the EVAP system.
- If the floating indicator is below the red flag, test for a blockage or restriction in the EVAP system.
- If the vehicle passes the Circuit/System Verification test, then operate the vehicle within the conditions for running the DTC. You may also operate the vehicle within the conditions that are captured in the Freeze Frame/Failure Records List.
