Programming Using Scan Tool

  1. Access PROGRAMMING menu on scan tool. Under DISABLE AUTOMATIC RECIRCULATION - YES/NO function, select NO. If NO is selected, manual or automatic air recirculation can be selected. If YES is selected, then air recirculation can only be selected manually.
  2. Under CIRCULATION PUMP - YES/NO function, select YES if vehicle is equipped with a coolant circulation pump. If vehicle is not equipped with a coolant circulation pump, select NO. If YES is selected and vehicle is not equipped with a circulation pump, an ACC control panel DTC 19 will be displayed on right side of control panel. If this occurs, select NO during ACC control module programming.
  3. Under CALIBRATION FOR CLIMATE ZONE - WARM CLIMATE/COLD CLIMATE function, make the selection most appropriate for climate region. Programming for climate zone specifies direction mixed-air flap is moved during ACC control module calibration. For WARM CLIMATE, calibration is toward maximum cold. For COLD CLIMATE, calibration is toward maximum heat. This function ensures that mixed-air flap does not leak when in position used most often for selected climate zone.
