   1. Connect the GTS to the DLC3.

   2. Turn the power switch on (IG).

   3. Enter the following menus: Powertrain / Hybrid Control / Data List / Sport Up Shift Sens State, Sport Dwn Shift Sens State.

      
      Powertrain > Hybrid Control > Data List

      Tester Display
      Sport Up Shift Sens State
      Sport Dwn Shift Sens State

   4. Read the value displayed on the GTS.

      
      Powertrain > Hybrid Control > Data List

      Tester Display	Measurement Item	Range	Normal Condition
