STEERING ANGLE ADJUSTMENT
The steering angle output value detected with the gyroscope is
adjusted.
SPEED CALIBRATION
During normal driving, distance error caused by tire wear and tire
pressure change is automatically adjusted for by the automatic dis-
tance correction function. This function, on the other hand, is for
immediate adjustment, in cases such as driving with tire chain fitted
on tires.

STEERING SWITCH
DescriptionINFOID:0000000001696137
When one of the steering wheel audio control switches is pushed, the resistance in the steering wheel audio
control switch circuit changes depending on which button is pushed.
Diagnosis ProcedureINFOID:0000000001696138
1.CHECK STEERING WHEEL AUDI O CONTROL SWITCH RESISTANCE
1. Turn ignition switch OFF.
2. Disconnect steering wheel audio control switch connector M102.
3. Check resistance between steering switch connector terminals.
Do the steering wheel audio control switches check OK?
YES >> GO TO 2
NO >> Replace steering wheel audio control switch. Refer to AV-174, "
Removal and Installation".
2.CHECK HARNESS
1. Turn ignition switch OFF.
2. Disconnect AV control unit connector M42 and spiral cable con- nector M30.
3. Check continuity between AV control unit harness connector M42 (A) and spiral cable harness connector M30 (B).
4. Check continuity between AV control unit connector M42 (A) and ground.
Are the continuity results as specified?
YES >> GO TO 3
NO >> Repair harness.

AV-160
< SYMPTOM DIAGNOSIS >[AUDIO SYSTEM]
NORMAL OPERATING CONDITION
- Because calculation of the current location cannot be
done when traveling 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.
Vehicle Mark Jumps
In the following cases, the vehicle mark may appear to ju mp as a result of automatic correction of the current
location.
• When map matching has been done
- If the current location and the vehicle mark are diff erent when map matching is done, the vehicle mark may
seem to jump. At this time, the location may be “corre cted” 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 vehicle mark are different when the location is corrected using GPS measure-
ments, the vehicle mark may seem to jump. At this time, the location may be “corrected” to a location which
is not on a road.
Vehicle Mark is in a River or Sea
The navigation system moves the vehicle mark with no distinction between land and rivers or sea. If the vehi-
cle mark is somehow out of place, it may appear that the vehicle is driving in a river or the sea.
Vehicle Mark Automatically Rotates
The system wrongly memorizes the rotating status as st opping when the ignition switch is turned ON with the
turntable rotating. That causes the vehicle mark to rotate when the vehicle is stopped.
When Driving on Same Road, Sometimes Vehicle Mark is in Right Place and Sometimes it is in 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 lo cation has never been wrong, conditions may cause the
vehicle mark to deviate.
