PROCEDURE


  1. CHECK VEHICLE SIGNAL (OPERATION CHECK)


    1. A01QTGB

      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

      This display is updated once per second. As a result, it is normal for the display to lag behind the actual shift lever position.
