    NG : REPLACE SWITCH WIRE 

    OK : GO TO NEXT STEP 

  5. CHECK HARNESS AND CONNECTOR (SPIRAL CABLE - ECM) 
    1. Connect the spiral cable connector and steering pad switch connector.
    2. Disconnect the ECM connector.
    3. Measure the resistance according to the value(s) in the table below when the paddle shift is moved to each position.

      Standard resistance 

      TESTER CONNECTION SPECIFIED CONDITION

      Paddle Shift Position Tester Connection Specified Condition
      Pull continuously "+" (Up shift) A6-30 (SFTU) - Body ground Below 1 Ω
      Release "+" (Up shift)   10 kΩ or higher
      Pull continuously "-" (Down shift) A6-19 (SFTD) - Body ground Below 1 Ω
      Release "-" (Down shift)   10 kΩ or higher
