Trouble Diagnoses
EL-426
Possible cause Drive condition Service procedure
AreaSlippery road surfaceOn wet, icy, or gravel road where
frequent wheel slippage occurs, dis-
tance calculations may be errone-
ous. The position marker may show
the vehicle to be in inaccurate posi-
tion.
If the position marker does
not move to the correct posi-
tion even after the vehicle
has been driven approxi-
mately 10 km (6 miles), per-
form ªAdjust Current Loca-
tionº MODE (EL-421). If
necessary, perform ªSpeed
Calibrationº (EL-413). Slanted areaHilly areas where the road has
banked curves. When the vehicle
enters these banked curves, there
may be an error in steering angle
measurement. The position marker
may show the vehicle to be in inac-
curate position.
Map
dataMap display for a given road does not appear.
SEL699V
When the vehicle is driven on a
newly constructed road that does
not appear on the existing map. Map
marking and calibration are not pos-
sible. The position marker may indi-
cate inaccurate position in close
proximity to the actual position.
Subsequently, when the vehicle is
driven on a road which is available
as map data, the position marker
may still indicate an inaccurate posi-
tion.
The vehicle is driven on a road whose course has
been altered (usually to improve the road or to
eliminate some hazard).
SEL700V
When the map data shown on the
display and the actual conditions are
different. Map matching will not be
possible. The position marker may
indicate inaccurate position in close
proximity to the actual position. If the
vehicle is driven on the indicated
road, further errors may occur.
Vehicle Use of tire chains (Stormy weather)Tire chains will affect distance sens-
ing. The position marker may indi-
cate inaccurate position.If the position marker does
not move to the correct posi-
tion even after the vehicle
has been driven approxi-
mately 10 km (6 miles), per-
form ªSpeed Calibrationº (EL-
413). After removing the tire
chains, sensing accuracy
may recover by itself.

This Condition Is Not Abnormal (Cont'd)
EL-434
Possible cause Drive condition Service procedure
Opera-
tionDriving immediately after starting engine.The gyro (angular velocity sensor)
needs about 15 seconds after the
engine is started to precisely sense
the angular velocity.
Directional sensing errors will occur
if the vehicle is moved immediately
after starting the engine. The posi-
tion marker may indicate inaccurate
position.Wait a few moments
between starting the engine
and actually driving the
vehicle.
Continuous driving for long distances (non-stop)When the vehicle is driven continu-
ously without stopping over a long
distance, errors in directional sens-
ing may occur. The position marker
may indicate inaccurate position.Stop the vehicle. Perform
ªSpeed Calibrationº (EL-413).
Rough or violent drivingWheel spinning (peeling out) or simi-
lar rough driving techniques can
adversely affect sensing accuracy.
The position marker may indicate
inaccurate position.If the position marker does
not move to the correct posi-
tion even after the vehicle
has been driven approxi-
mately 10 km (6 miles), per-
form ªAdjust Current Loca-
tionº MODE (EL-421).

duresPositional calibration precision
SEL701V
If current vehicle location is roughly
set, the system may be unable to
locate the road that the vehicle is
traveling on. (This is especially true
in an area where there are many
roads.)Perform ªAdjust Current
Locationº MODE (EL-421)
within a precision standard of
1 mm (0.04 in) on the dis-
play.
NOTE:
During calibration, use the
most detailed map possible.
Position calibration direction
SEL702V
When calibrating the position, check
the vehicle direction. If the vehicle
direction is not correct, subsequent
precision of current location will be
affected.Perform ªAdjust Current

EL-421.

Possible cause:
Ð: Vehicle running ---: IndicationDrive condition Service procedure
Road
shapesY-intersection
SEL703V
In Y-intersections with a very gradual
change in course, a directional sens-
ing may be inaccurate. This may
result in the position marker giving
the wrong road indication.
If the position marker does
not move to the correct posi-
tion even after the vehicle
has been driven approxi-
mately 10 km (6 miles), per-
form ªStore placeº. If
required, also perform
ªAdjust Current Locationº
MODE (EL-421). Spiral road
SEL704V
On loop bridges and similar struc-
tures which result in a large and
continuous turn, turning angle may
be sensed inaccurately. As a result,
the position marker may separate
from the route on the map.
Straight road
SEL705V
In long distance driving on a straight
road or road with very gradual
curves, map marking inaccuracies
may occur. In such cases, the posi-
tion marker may stray from the route
being traveled during subsequent
turns due to inaccurate distance cal-
culation.
Winding road
SEL706V
Directional sensing precision errors
may occur when traveling on wind-
ing roads. During map matching, the
position marker may stray to an
adjacent road having a similar
shape. Subsequent position marker
error may occur.
Grid-like road shape
SEL707V
Directional sensing and distance
sensing, precision errors may occur
because of many roads having a
similar shape in the immediate area.
During map matching, the position
marker may stray to an adjacent
road having a similar shape. Subse-
quent position marker error may
occur.
Parallel roads
SEL708V
When driving on a parallel road,
map matching errors may occur.
Subsequent position marker error
may also occur.
