CAUTION / NOTICE / HINT

NOTICE:

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


PROCEDURE

1.CHECK VEHICLE SIGNAL (DISPLAY CHECK MODE)
a.
E270655

Enter the "Function Check/Setting I" mode and select "Vehicle Signal".


b.

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


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.



Result:
Proceed to
