   Sports Mode	Indicates the S position	Shift from D to S and back to D	Changes from OFF to ON and back to OFF

NG → See step   6 

OK: Go to next step 

1. Select the following menu items: Powertrain / Hybrid Control / Data List / Sports Shift UP Signal, Sports Shift Down Signal.
2. Read the data list.

   OK

   Tester Display	Description	Inspection Condition	Specified Condition
   Sports Shift UP Signal	Indicates the transmission control switch (+)	Shift from S to + and back to S	Changes from OFF to ON and back to OFF
   Sports Shift Down Signal	Indicates the transmission control switch (-)	Shift from S to - and back to S	Changes from OFF to ON and back to OFF

NG → See step   4 

OK: Go to next step 

1. Check for intermittent problems. Refer to CHECK FOR INTERMITTENT PROBLEMS .
   1. Move the shift lever to the S position and jiggle the wire harness and connector.
   2. Move the shift lever to the + and - positions and jiggle the wire harness and connector.

NG → REPAIR OR REPLACE MALFUNCTIONING PARTS, COMPONENT AND AREA 

OK → See step   10

3. Turn the power switch on (IG).
4. Measure the voltage according to the value(s) in the table below.

   Standard voltage

   Tester Connection	Switch Condition	Specified Condition
   A75-12 (M) - A75-7 (E1)	Power switch on (IG) Except for S position	Below 1 V
   A75-12 (M) - A75-7 (E1)	Power switch on (IG) S position	11 to 14 V

   NOTE:

   Turning the power switch on (IG) with the hybrid vehicle control ECU connector disconnected causes other DTCs to be stored. Clear the DTCs after performing this inspection.

5. Measure the resistance according to the value(s) in the table below.

   Standard resistance

   Tester Connection	Switch Condition	Specified Condition
   A75-11 (SFTU) - Body ground	+ position	Below 1 Ω
   A75-11 (SFTU) - Body ground	Neutral (S position)	10 kΩ or higher
