      2 (OT-) -10 (OT+) 79 Ω to 156 kΩ
      2 (OT-) - Body ground 1 MΩ or higher
      10 (OT+) - Body ground 1 MΩ or higher

      HINT:

      If the resistance is out of the specified range of either of the ATF temperatures shown in the table below, the driveability of the vehicle may decrease.
