  • Refer to the J 41413-200Β  operation manual for detailed instructions.

  2. Seal the EVAP system and use the flow meter on the J 41413-200Β  , 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 41413-200Β  to apply smoke to the EVAP system at the service port or the purge tube until the leak is located.
