Symptom

Map screen and BIRDVIEW™
Name of the place vary with the
screen. Some thinning of the character data is done to pre-
vent the display becoming to complex. In some
cases and in some locations, the display contents
may differ.
The same place name, street name, etc. may not
be displayed every time on account of the data
processing. System is not malfunctioning.
Vehicle mark is not positioned cor-
rectly. Vehicle is transferred by ferry or by towing after its
ignition switch is turned to OFF. Drive the vehicle for a while in the GPS sat-
ellite signal receiving condition.
Screen will not switch to nighttime
mode after the lighting switch is
turned ON. The daytime screen is selected by the “SWITCH
SCREENS” when the last time the screen dim-
ming setting is done.
Switching between daytime/nighttime screen may
be inhibited by the automatic illumination adjust-
ment function. Perform screen dimming and select the
nighttime screen by “SWITCH SCREENS”.
Map screen will not scroll in accor-
dance with the vehicle travel. Current location is not displayed.
Press “MAP” button to display the current lo-
cation.
Vehicle mark will not be shown. Current location is not displayed. Press “MAP” button to display the current lo-
cation.
Accuracy indicator (GPS satellite
mark) on the map screen stays
gray. GPS satellite signal is intercepted because the ve-
hicle is in or behind a building.
Move the vehicle out to an open space.
GPS satellite signal cannot be received because
an obstacle is placed on top of the instrument pan-
el. Do not place anything on top of the meter dis-
play (instrument panel).
GPS satellites are not visible from current location. Wait until GPS satellites are visible by mov- ing the vehicle.
Vehicle location accuracy is low. Accuracy indicator (GPS sate llite mark) on the
map screen stays gray. Current location is not determined.
Vehicle speed setting by the vehicle speed pulse
has been deviated (advanced or retarded) from
the actual vehicle speed because tire chain is fit-
ted or the system has been used on another vehi-
cle. Drive the vehicle for a while [for approx. 30
minutes at approx. 30 km/h (19 MPH)] and
the deviation will be automatically adjusted. If
advancement or retard still occur, perform
the distance adjustment by CONFIRMA-
TION/ADJUSTMENT mode of diagnosis
function.
Map data has error or omission. (Vehicle mark is
always deviated to the same position.) As a rule, an updated map DVD–ROM will be
released once a year.
Symptom
Cause Remedy
Destination cannot be set. Destination to be set is on an expressway. Set the destination on an ordinary road.
Passing point is not searched
when re-searching the route. The vehicle has already passed the passing point,
or the system judged so. To include the passing points that have been
passed into the route again, set the route
again.
Route information will not be dis-
played. Route searching has not been done.
Set the destination and perform route
searching.
Vehicle mark is not on the recommended route. Drive on the recommended route.
Route guide is turned OFF. Turn route guide ON.
Route information is not available on the dark pink
route. System is not malfunctioning.
After the route searching, no guide
sign will appear as the vehicle
goes near the entrance/exit to the
toll road. Vehicle mark is not on the recommended route.
(On the display, only guide signs related to the rec-
ommended route will be shown.)
Drive on the recommended route.

NORMAL OPERATING CONDITION
NOTE:
Except for the ordinance-designated cities. (Malfunctioning areas may be changed in the updated map disc.)
Examples of Current-Location Mark Displacement
Vehicle's travel amount is calculated by reading its trav
el distance and turning angle. Therefore, if the vehicle
is driven in the following manner, an error will occur in the vehicle's current location display. If correct location
has not been restored after driving the vehicle for a while, perform location correction.
Detouring route is recommended. In some areas, highways (gray routes) are not
used for the search. (Note). Therefore, detour
route may be recommended. Set the route closer to the basic route (gray
route).
A detour route may be shown when some traffic
regulation (one-way traffic, etc.) is set at the area
around the starting point or the destination. Slightly move the starting point or the destina-
tion, or set the passing point on the route of
your choice.
In the area where highways (gray routes) are
used for the search, left turn has priority around
the current location and the destination (passing
points). For this reason, the recommended route
may be detouring. System is not malfunctioning.
Landmarks on the map do not
match the actual ones. This can be happen due to omission or error in
the map data. As a rule, an updated map DVD-ROM will be
released once a year. Wait until the latest
map has become available.
Recommended route is far from
the starting point, passing points,
and destination. Starting point, passing points, and destination of
the route guide were set far from the desired
points because route searching data around
these area were not stored. Reset the destination onto the road nearby. If
this road is one of the highways (gray routes),
an ordinary road nearby may be displayed as
the recommended route.

BCM (Body Control Module) controls
the various electrical components. It inputs the information required to
the control from CAN communication and the si gnal received from each switch and sensor.
BCM has combination switch reading function for reading the operation status of combination switches (light,
turn signal, wiper and washer) in addition to a function fo r controlling the operation of various electrical com-
ponents. It also has the signal transmission function as the passed point of signal and the power consump-
tion control function that reduces the power consumption with the ignition switch OFF.
BCM is equipped with the diagnosis function that perfo rms the diagnosis with CONSULT-III and various set-
tings.

BCM reads the status of the combination switch (light, turn signal, wiper and washer) and recognizes the
status of each switch.
BCM is a combination of 5 output terminals (OUTPUT 1 - 5) and 5 input terminals (INPUT 1 - 5). It reads a
maximum of 20 switch status.

COMBINATION SWITCH READING FUNCTION
Description
BCM reads the status of the combination switch at 10 ms interval normally.
NOTE:
BCM reads the status of the combination switch at 20 ms interval when BCM is controlled at low power con-
sumption control mode.
BCM operates as follows and judges the status of the combination switch.
- INPUT 1 - 5 outputs the voltage waveforms of 5 systems simultaneously.
- It operates the transistor on OUTPUT side in the following order: OUTPUT 5 → 4 → 3 → 2 → 1.
