Trouble Diagnoses (Cont'd)
EL-4217

Cause (condition) Driving condition Remarks (correction, etc.)
Road con®gu-
ration Y-intersections
ELK0192D
At a Y intersection or similar gradual
division of roads, error the direction
of travel deduced by the sensor may
result in the current location mark
appearing on the wrong road.
If after travelling about 10 km (6
miles) the correct location has not
been restored, perform location cor-
rection and, if necessary, direction
correction.
Spiral roads
ELK0193D
When driving on a large, continuous
spiral road (such as loop bridge),
turning angle error is accumulated
and the vehicle mark may deviate
from the correct location.
Straight roads
ELK0194D
When driving on a long, straight road
and slow curve without stopping,
map-matching does not work effec-
tively enough and distance errors
may accumulate. As a result, the
vehicle mark may deviate from the
correct location when the vehicle
turned at a corner.
Zigzag roads
ELK0195D
When driving on a zigzag road, the
map may be matched to other roads
in the similar direction nearby at
every turn, and the vehicle mark may
deviate from the correct location.
Roads laid out in a grid pattern
ELK0196D
When driving at where roads are laid
out in a grid pattern, where many
roads are running in the similar
direction nearby, the map may be
matched to them by mistake and the
vehicle mark may deviate from the
correct location.
Parallel roads
ELK0197D
When two roads are running in paral-
lel (such as highway and sideway),
the map may be matched to the
other road by mistake and the
vehicle mark may deviate from the
correct location.

Cause (condition) Driving condition Remarks (correction, etc.)
Place In a parking lot
SEL709V
When driving in a parking lot, or
other location where there are no
roads on the map, matching may
place the vehicle mark on a nearby
road. When the vehicle returns to the
road, the vehicle mark may have
deviated from the correct location.
When driving in circle or turning the
steering wheel repeatedly, direction
errors accumulate, and the vehicle
mark may deviate from the correct
location.
If after travelling about 10 km (6
miles) the correct location has not
been restored, perform location cor-
rection and, if necessary, direction
correction.
Turn table
SEL710V
When the ignition switch is OFF, the
navigation system cannot get the
signal from the gyroscope (angular
speed sensor). Therefore, the dis-
played direction may be wrong and
the correct road may not be easily
returned to after rotating the vehicle
on a turntable with the ignition OFF.
Slippery roads On snow, wet roads, gravel, or other
roads where tires may slip easily,
accumulated mileage errors may
cause the vehicle mark to deviate
from the correct road.
Slopes When parking in sloped garages,
when travelling on banked roads, or
in other cases where the vehicle
turns when tilted, an error in the turn-
ing angle will occur, and the vehicle
mark may deviate from the road.
Map data Road not displayed on the map
screen
SEL699V
When driving on new roads or other
roads not displayed on the map
screen, map matching does not func-
tion correctly and matches the loca-
tion to a nearby road. When the
vehicle returns to a road which is on
the map, the vehicle mark may devi-
ate from the correct road.
Different road pattern (Changed due
to repair)
ELK0201D
If the road pattern stored in the map
data and the actual road pattern are
different, map matching does not
function correctly and matches the
location to a nearby road. The
vehicle mark may deviate from the
correct road.
Vehicle Use of tire chains When tire chains are used, the mile-
age is not correctly detected, and the
vehicle mark may deviate from the
correct road.Drive the vehicle for a while. If the
distance is still deviated, adjust it by
using the distance adjustment func-
tion. (If the tire chain is removed,
recover the original value.)

Precautions
for driving Just after the engine is started
If the vehicle is driven off just after
the engine is started when the gyro-
scope (angular speed sensor) cor-
rection is not completed, the vehicle
can lose its direction and may have
deviated from the correct location.Wait for a short while before driving
after starting the engine.
Continuous driving without stopping When driving long distances without
stopping, direction errors may
accumulate, and the current location
mark may deviate from the correct
road.Stop and adjust the orientation.
Abusive driving Spinning the wheels or engaging in
other kinds of abusive driving may
result in the system being unable to
perform correct detection, and may
cause the vehicle mark to deviate
from the correct road.If after travelling about 10 km (6
miles) the correct location has not
been restored, perform location cor-
rection and, if necessary, direction
correction.
How to correct
location Position correction accuracy
SEL699V
If the accuracy of location settings is
poor, accuracy may be reduced
when the correct road cannot be
found, particularly in places where
there are many roads.
Enter in the road displayed on the
screen with an accuracy of approx. 1
mm.
NOTE:
Whenever possible, use detailed
map for the correction.
Direction when location is corrected
SEL702V
If the accuracy of location settings
during correction is poor, accuracy
may be reduced afterwards. Perform direction correction.
THE CURRENT POSITION MARK SHOWS A POSITION WHICH IS COMPLETELY WRONG
In the following cases, the current location mark may appear on completely different position in the map
depending on the GPS satellite signal receiving conditions. In this case, perform location correction and
direction correction.
+
When location correction has not been done
Ð If the receiving conditions of the GPS satellite signal is poor, if the current location mark becomes out of place, it may move to a completely different location and not come back if location correction is not done.
The position will be corrected if the GPS signal can be received.
+ When the vehicle has traveled by ferry, or when the vehicle has been being towed
Ð Because calculation of the current location cannot be done when travelling with the ignition OFF, for example when travelling by ferry or when being towed, the location before travel is displayed. If the pre-
cise location can be detected with GPS, the location will be corrected.
THE CURRENT POSITION MARK JUMPS
In the following cases, the current location mark may appear to jump as a result of automatic correction of the
current location.
+When map matching has been done
Ð If the current location and the current location mark are different when map matching is done, the current location mark may seem to jump. At this time, the location may be ªcorrectedº to the wrong road or to a
location which is not on a road.
+ When GPS location correction has been done
Ð If the current location and the current location mark are different when the location is corrected using GPS measurements, the current location mark may seem to jump. At this time, the location may be ªcorrectedº
to a location which is not on a road.

THE CURRENT LOCATION MARK IS IN A RIVER OR THE SEA
The navigation system moves the current location mark with no distinction between land and rivers or sea. If
the location mark is somehow out of place, it may appear that the vehicle is driving in a river or the sea.
WHEN DRIVING ON THE SAME ROAD, SOMETIMES THE CURRENT LOCATION MARK IS IN
THE RIGHT PLACE AND SOMETIMES IT IS THE WRONG PLACE
The conditions of the GPS antenna (GPS data) and gyroscope (angular speed sensor) change gradually.
Depending on the road traveled and the operation of the steering wheel, the location detection results will be
different. Therefore, even on a road on which the location has never been wrong, conditions may cause the
vehicle mark to deviate.
LOCATION CORRECTION BY MAP MATCHING IS SLOW
+The map matching function needs to refer to the data of the surrounding area. It is necessary to drive some
distance for the function to work.
+ Because map matching operates on this principle, when there are many roads running in similar direc-
tions in the surrounding area, no matching determination may be made. The location may not be corrected
until some special feature is found.
ALTHOUGH THE GPS RECEIVING DISPLAY IS GREEN, THE VEHICLE MARK DOES NOT
RETURN TO THE CORRECT LOCATION
+The GPS accuracy has an error of about 10 m (30 ft). In some cases the current location mark may not
be on the correct street, even when GPS location correction is done.
+ The navigation system compares the results of GPS location detection with the results from map-match-
ing location detection. The one which is determined to have higher accuracy is used.
+ GPS location correction may not be performed when the vehicle is stopped.
THE NAME OF THE CURRENT PLACE IS NOT DISPLAYED
The current place name may not be displayed if there are no place names displayed on the map screen.
CONTENTS OF THE DISPLAY DIFFER FOR THE BIRDVIEW TAND THE (FLAT) MAP SCREEN
Difference of the BIRDVIEW Tscreen from the ¯at map screen are as follows.
+ The current place name displays names which are primarily in the direction of vehicle travel.
+ The amount of time before the vehicle travel or turn angle is updated on the screen is longer than for the
(¯at) map display.
+ The conditions for display of place names, roads, and other data are different for nearby areas and for
more distant areas.
+ Some thinning of the character data is done to prevent 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 be displayed multiple times.

Features (TB48 Engine Models)
CAN COMMUNICATION SYSTEM DESCRIPTION
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Many
electronic control units are equipped onto a vehicle, and each control unit shares information and links with
other control units during operation (not independent). In CAN communication, control units are connected with
2 communication lines (CAN H line, CAN L line) allowing a high rate of information transmission with less wir-
ing. Each control unit transmits/receives data but selectively reads required data only.
SYSTEM CONSTRUCTION
Magnet clutch control
When A/C switch is pressed, turn fan control dial to ON or set mode control dial to DEF position, A/C auto
amp. inputs compressor ON signal to ECM.
ECM judges whether compressor can be turned ON, based on each sensor status (refrigerant pressure sen-
sor signal, throttle angle, etc.).
When sending compressor ON signal to ECM from A/C auto amp., ECM simultaneously sends compressor
feedback signal to uni®ed meter C/U via CAN communication line.
Uni®ed meter control unit sends compressor feedback signal to A/C auto amp. Then, A/C auto amp. uses input
compressor feedback signal to control air inlet.
