      Result

      Result Proceed to
      Total distance driven is less than 200000 km (124280 mile) A
      Total distance driven is 200000 km (124280 mile) or more Current total distance driven - total distance driven when hybrid battery terminal block replaced = less than 200000 km (124280 mile) *1
      Other than above B

      HINT: 

      *1: If the hybrid battery terminal block has been replaced, use the total distance driven since it was replaced.

    Result:
