INSPECTION PROCEDURE

Note

Inspect the fuses for circuits related to this system before performing the following inspection procedure.

PROCEDURE


  1. CHECK NAVIGATION RECEIVER ASSEMBLY (DISPLAY CHECK MODE)


    1. A005SQ5E17

      Enter the "Display Check" mode and select "Vehicle Signal Check Mode" Click here.

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

      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 operation.
