Circuit/System Testing

WARNING: This page is about a different car, the 2007 Hummer H2. However, it is still accessible from the selected car via links, so may be relevant.
IMPORTANT:
  • Larger volume fuel tanks and/or those with lower fuel levels may require several minutes for the floating indicator to stabilize.
  • Refer to the J 41413-200 operation manual for detailed instructions.

  1. Connect the J 41413-200 to the vehicle at the EVAP service port.
  2. Seal the EVAP system and use the flow meter on the J 41413-200 , calibrated to 0.51 millimeter (0.020 inch) to determine that there is no leak in the EVAP system.
    • If a leak is detected, use the J 41413-200 to apply smoke to the EVAP system at the service port until the leak is located.
