Diagnosis
No.Possible causeReference
page
1 NAVI control unit malfunction–
2 NAVI control unit judged no map DVD-ROM is inserted. –
3When “DVD-ROM error. Please check disc.” is shown.
1. Eject map DVD-ROM and check if it is compatible with the system.
2. Check ejected DVD-ROM for dirt, damage, and warpage.
3. If no error is found, insert a known good map DVD-ROM of the same type and perform self-diagnosis
again. If same result is shown, the NAVI control unit is malfunctioning. If result is normal, the map DVD-
ROM is malfunctioning.–
4If “Error found in DVD-ROM or DVD-ROM driver in control unit. Please perform diagnosis in accordance
with service manual” is shown, carry out same inspection as diagnosis No. 3.–
5GPS antenna system
1. Visually check for a broken wire in the GPS antenna coaxial cable.
2. Disconnect the GPS antenna connector and check that approximately 5V is supplied from NAVI control
unit. If not, the NAVI control unit is inoperative. If the voltage is supplied, replace the GPS antenna and
perform self-diagnosis again. If the same result is shown, the NAVI control unit is inoperative.–

Vehicle Speed Signal CheckEKS00F3D
1. VEHICLE SPEED OPERATION CHECK
Does speedometer is operated normally?
Ye s o r N o
Ye s > > G O T O 2 .
No >> Check combination meter trouble diagnosis. Refer to DI-26, "
Vehicle Speed Signal Inspection
[with ESP]" in “COMBINATION METERS”.
2. HARNESS CHECK
1. Turn the ignition switch OFF.
2. Disconnect NAVI control unit connector and combination meter connector.
3. Check continuity between NAVI control unit harness connector
M117 terminal 28 (LG) and Unified meter control unit harness
connector M44 terminal 11 (LG).
4. Check continuity between NAVI control unit harness connector
M117 terminal 28 (LG) and ground.
OK or NG
OK >> GO TO 3.
NG >> Repair harness or connector.
3. VEHICLE SPEED SIGNAL CHECK
1. Connect NAVI control unit and combination meter connector.
2. Start engine and drive vehicle at more than 40 km/h (25MPH).
3. Check the signal between NAVI control unit harness connector
M117 terminal 28 (LG) and ground with CONSULT-ll or oscillo-
scope.
OK or NG
OK >> Replace NAVI control unit.
NG >> Check combination meter system. Refer to DI-20, "
Diagnosis Flow" in “COMBINATION
METERS”. 28 (LG)-11 (LG) Continuity should exist.
28 (LG) - Ground Continuity should not
exist.

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 direc-
tion correction.

When location correction has not been done
–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
–Because calculation of the current location cannot be done when travelling with the ignition OFF, for
example when traveling by ferry or when being towed, the location before travel is displayed. If the precise
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
–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 ″corrected″ to the wrong road or to a
location which is not on a road.

When GPS location correction has been done
–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 ″corrected″
to a location which is not on a road.
Precautions for
drivingJust after the engine is startedIf 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 driv-
ing after starting the engine.
Continuous driving without stopping When driving long distances without
stopping, direction errors may accu-
mulate, 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
correction and, if necessary,
direction correction.
How to correct
locationPosition correction accuracy
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
If the accuracy of location settings
during correction is poor, accuracy
may be reduced afterwards.Perform direction correction. Cause (condition) Driving condition Remarks (correction, etc.)
