  1. Enter the "Function Check/Setting" screen and select "Connection status" (HILUX_TGN26 RM000003A3N01YX.html).

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

    OK:
    Shift Lever Position
    		Display
    R
    		High
    Except R
    		Low
    HINT:
    This display is updated once per second. As a result, it is normal for the display to lag behind the actual shift lever position.
