Circuit/System Testing

NOTE:
  • 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:  EEST to the vehicle at the EVAP service port. For vehicles without a service port, disconnect the purge tube at the quick connector on the EVAP canister side of the purge solenoid valve and install the CH 48096:  Port Tool.
  2. Seal the EVAP system and use the flow meter on the J 41413-200:  EEST, calibrated to 0.51 mm (0.020 in) to determine that there is no leak in the EVAP system.
    • If a leak is detected use the J 41413-200:  EEST to apply smoke to the EVAP system at the service port or the purge tube until the leak is located.
