Component Description
The mass air ¯ow (MAF) sensor is placed in the stream of intake
air. It measures the intake air ¯ow rate by measuring a part of the
entire intake air ¯ow. The mass air ¯ow sensor controls the tem-
perature of the hot wire to a certain amount. The heat generated
by the hot wire is reduced as the intake air ¯ows around it. The
more air, the greater the heat loss.
Therefore, the electric current supplied to hot wire is changed to
maintain the temperature of the hot wire as air ¯ow increases. The
ECM detects the air ¯ow by means of this current change.
CONSULT-II Reference Value in Data Monitor

Speci®cation data are reference values.

Speci®cation data are reference values, and are measured between each terminal and ground.
CAUTION:
Do not use ECM ground terminals when measuring input/output voltage. Doing so may damage the

Self-Diagnosis Function
DESCRIPTION
+Diagnosis function consists of the self-diagnosis mode performed automatically and the CONFIRMATION/
ADJUSTMENT mode operated manually.
+ Self-diagnosis mode checks for connections between the units constituting this system, analyzes each
individual unit at the same time, and displays the results on the LCD screen.
+ CONFIRMATION/ADJUSTMENT mode is used to perform trouble diagnosis that require operation and
judgment by an operator (malfunction that cannot be automatically judged by the system), to check/change
the set value, and to display the History of Errors of the navigation system.
DIAGNOSIS ITEM
Mode Description
Self-diagnosis +
NAVI Control unit diagnosis (DVD-ROM drive will not be diagnosed when no
map DVD-ROM is in it.).
+ Performs diagnosis of each unit and connections between control unit and
GPS antenna, as well as between control unit and each unit.
Con®rmation/
Adjustment Display
Color tone and shading of the screen can be checked by the display of a color
bar and a gray scale.
Vehicle signals Analyzes the following vehicle signals: Vehicle speed signal, light signal, ignition
switch signal, and reverse signal.
Navigation Display Longi-
tude & Lati-
tude
Display the map. Use the joystick to adjust position. Longitude and latitude will be
displayed.
Speed Calibra-
tion Under ordinary conditions, the navigation system distance measuring function will
automatically compensate for minute decreases in wheel and tire diameter
caused by tire wear or low-pressure. Speed calibration immediately restores sys-
tem accuracy in cases such as when distance calibration is needed because of
the use of tire chains in inclement weather.
Angle Adjust-
ment Corrects difference between actual turning angle of a vehicle and turning angle of
the car mark on the display.
Initialize Loca-
tion This mode is for initializing the current location. Use when the vehicle is trans-
ported a long distance on a trailer, etc.
History of Errors Diagnosis results previously stored in the memory (before turning ignition switch
ON) are displayed in this mode. Time and location when/where the errors
occurred are also displayed.

OPERATION PROCEDURE
1. Start the engine.
2. Push and hold ªMAPº and ªDAY/NIGHTº switches simulta-
neously for 5 seconds or more.

Trouble Diagnoses (Cont'd)
EL-4207

Cause (condition) Driving condition Remarks (correction, etc.)
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.
