   INT/A TEMP SE	Below 40°C (104°F)
   Difference between "COOLANT TEMP/S" and "INT/A TEMP SE"	Within 6°C (11°F)

   If they are within the specified range, perform the following steps.

   If they are out of the specified range, soak the vehicle to meet the above conditions. Then perform the following steps.
