PROCEDURE


  1. CHECK VEHICLE SIGNAL (OPERATION CHECK)


    1. B00260I

      Enter the "Vehicle Signal Check Mode" screen.

      Refer to check Vehicle Signal in Operation Check.

      Click here

    2. Check that the display changes between ON and OFF according to the shift lever position.

      OK
      Shift Lever Position Display
      R ON
      Except R OFF

      Tech Tips
