1 CLEAN THE INFRARED RAY EMITTED PORTION
(a) Clean the infrared ray emitted portion.
(1) Clean the infrared ray emitted portion on the navi-
gation controller holder and navigation controller
assy.
(2) Check whether the same malfunction occurs.
Standard: The function returns to normal.

VEHICLE POSITION MARK ROTATES ARBITRARILY (MAP ROTATES ARBITRARILY)
WIRING DIAGRAM
INSPECTION PROCEDURE
1CHECK AND OPERATE AGAIN
(a)Turn the ignition switch from OFF to ON, check that the malfunction disappea\
rs.
Standard: Malfunction disappears
HINT:
Even if the system works correctly, the following conditions may be seen: vehicle position mark turns, or the
map turns unwillingly. (It is because by turning the IG switch to ACC or ON during turning, \
navigation system
stores based on the angular speed). In that case, turn the IG switch from OFF to ACC\
or ON to return the
correct function.
