B 

REPLACE HV BATTERY JUNCTION BLOCK ASSEMBLY. Refer to  REMOVAL [11/2015 - 12/2018]  , or refer to  REMOVAL [12/2018 - 07/2020]  , or refer to  REMOVAL [07/2020 -] 

Result: 

A 

See step  3

1. Read the odometer to check the total distance the vehicle has been driven.

   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.
