MULTI AV SYSTEM : System Description
INFOID:0000000006216216
Multi AV system means that the following systems are integrated.
COMMUNICATION SIGNAL
AV control unit function by transmitting/receiving dat a one by one with each unit (slave unit) that configures
them completely as a master unit by connecting between units that configure MULTI AV system with two AV
communication lines (H, L).
Two AV communication lines (H, L) adopt a twisted pair line that is resistant to noise.
AV control unit is connected by CAN communication, and it receives data signal from ECM and combination
meter It computes and displays fuel economy information value with the obtained information. Transmitting/
receiving of data signal is performed by BCM. Also, it transmits the required signal of vehicle setting and
receives the response signal.
AV control unit is connected with front display unit and serial communication, and it transmits the required
signal of display and display control and receives the response signal from front display unit.
NAVIGATION SYSTEM FUNCTION
Description
The AV control unit controls navigation function whil e GPS tuner has built-in map data, GYRO (angle speed
sensor), on the HDD (Hard Disk Drive).
The AV control unit inputs operation signal with communication signal, through display (touch panel) and multifunction switch and steering switch.
Guide sound is output to front speaker through BOSE am p. from AV control unit when operating navigation
system.
A vehicle position is calculated with the GYRO (angl e speed sensor), vehicle sensor, signal from GPS satel-
lite and map data stored on HDD (Hard Disk Drive), and transmits the map image signal (RGB image, RGB
area, RGB image synchronizing) to the display.
Position Detection Principle
The navigation system periodically calculates the current vehicle
position according to the following three types of signals.
Travel distance of the vehicle as determined by the vehicle speed
sensor
Vehicle turning angle determined by the gyroscope (angular speed
sensor)
The travel direction of the v ehicle determined by the GPS antenna
(GPS information)
The current position of the vehicle is then identified by comparing the
calculated vehicle position with map data, which is stored in the HDD
(Hard Disk Drive) (map-matching), and indicated on the screen with
a current location mark. More accurate data is used by comparing
position detection results from GPS to the map-matching.

The current position is calculated by detecting the travel distance
from the previous calculation point, and its direction change.
Travel distance The travel distance is generat ed from the vehicle speed sensor
input signal. The automatic distance correction function is adopted
for preventing a miss-detection of the travel distance because of
tire wear etc.
Travel direction The gyroscope (angular veloci ty sensor) and GPS antenna (GPS
information) generate the change of t he travel direction. Both have
advantages and disadvantages as per the following descriptions.
Input signals are prioritized in each situation. However, this order of priority may change in accordance with
more detailed travel conditions so that the tr avel direction is detected more accurately.
Map-matching
Map-matching repositions the vehicle on the road map when a new
location is judged to be more accurate. This is done by comparing
the current vehicle position (calculated by the normal position detec-
tion method) from the map data stored in the HDD (Hard Disk Drive).
There is a possibility that the vehicle position may not be corrected in the following case, and when vehicle is
driven over a certain distance or time in which GPS in formation is hard to receive. Correct manually the cur-
rent location mark on the screen.
In map-matching, several alternative routes are prepared and pri- oritized in addition to the road judged as currently driving on.
Therefore, due to errors in the distance and/or direction, an incor-
rect road may be prioritized, and the current location mark may be
repositioned to the incorrect road.
If two roads are running in parallel, they are of the same priority.
Therefore, the current location mark may appear on either of them
alternately, depending on maneuvering of the steering wheel and
configuration of the road, etc.

Type Advantage Disadvantage
Gyroscope (angular velocity
sensor) The turning angle is precisely detected.
Errors are accumulated when driving a long dis-
tance without stopping.
GPS antenna (GPS informa-
tion) The travel direction (North/South/East/West) is
detected. The travel direction is not precisely detected when
driving slowly.

DescriptionINFOID:0000000006216218
The AV control unit diagnosis function starts up with multifunction switch operation and the AV control unit
performs a diagnosis for each unit in the system during the on board diagnosis.
Perform a CONSULT-III diagnosis if the on board diagnosis does not start, e.g., the screen does not display
anything, the multifunction switch does not function, etc.
On Board Diagn osis FunctionINFOID:0000000006216219
MULTIFUNCTION SWITCH AND PRESET SWITCH SELF-DIAGNOSIS FUNCTION
The ON/OFF operation (continuity) of each switch in the multifunction switch and preset switch can be
checked.
Self-diagnosis Mode
Press the “BACK” switch and the “UP” switch of the 8-direction switches within 10 seconds after turning the ignition switch from
OFF to ACC and hold them for 3 seconds or more. Then the
buzzer sounds, all indicators of the preset switch illuminate, and
the self-diagnosis mode starts.
The continuity of each switch at the ON position can be checked
by pressing the switch. The buzzer sounds if the switch is normal.
NOTE:
The hazard switch and disk eject switch cannot be checked.
Finishing Self-diagnosis Mode
Self-diagnosis mode is canceled when turning the ignition switch OFF.
ON BOARD DIAGNOSIS
Description
The trouble diagnosis function has a self-diagnosis mode for conducting trouble diagnosis automatically and
a confirmation/adjustment mode for operating manually.
The self-diagnosis mode performs diagnoses on the AV control unit, connections between system compo-
nents as well as connections between AV contro l unit and GPS antenna. Then it displays the diagnosis
results on the display.
The confirmation/adjustment mode allows the technician to check, modify or adjust the vehicle signals and
set values, as well as to monitor the system erro r records and system communication status. The checking,
modifying or adjusting generally require human inte rvention and judgment (the system cannot make judg-
ment automatically).
