SYSTEM DESCRIPTION
Revision: 2007 April2007 M35/M45
BOSE Surround 5.1ch System

It amplifies the sound signal from the audio unit and the DVD
sound signal from DVD player, and then output them to each
speaker.

It receives the voice guidance signal from AV (NAVI) control unit
and output it to the front speaker.

It controls sound volume of each speaker when outputting TEL
voice and voice guidance.

It subjects to AudioPilot® processing when receiving sound sig-
nal from microphone for AudioPilot
® .

It subjects to Centerpoint® processing.
SATELLITE TUNER

The satellite tuner is connected with the audio unit via communi-
cation line.

It sends the received sound signal from the satellite radio
antenna to the audio unit.
AV CONTROL UNIT (WITHOUT NAVI)

It controls each unit of the system by the operation signal from
the multifunction switch and sends the image signal of operating
condition or vehicle information, etc. to the front display unit.

It receives the TEL input voice or the input voice at voice control
from the microphone. It receives the received TEL voice, and
then sends it to the audio unit.

It sends the voice guidance signal to BOSE amp (BOSE system)
and audio unit (BASE system).
NAVI CONTROL UNIT (WITH NAVI)

It controls each unit of the system by the operation signal from
the multifunction switch and sends the image signal of operating
condition or vehicle information, etc. to the front display unit.

It receives the TEL input voice or the input voice at voice control
from the microphone. It receives the received TEL voice, and
then sends it to the audio unit.

It sends the voice guidance signal to BOSE amp (BOSE system)
and audio unit (BASE system).

Signals are received from the gyro, the vehicle speed sensor,
and the GPS antenna. Vehicle location is determined by com-
bining this data with the data contained in the DVD-ROM map.
Location information is shown on liquid crystal display panel.

FRONT DISPLAY UNIT

It receives the RGB signal and the image signal of DVD player
and camera control unit from AV (NAVI) control unit.

The changing of image is controlled by the communication with
AV (NAVI) control unit.
DVD PLAYER

It sends the sound signal to the BOSE amp and sends the
image signal to the front display unit.

When the downmix function is turned ON when playing DVD,
the sound signal is sent to the audio unit.

It inputs the sound signal from auxiliary input jacks, and then
sends it to audio unit.
CAMERA CONTROL UNIT

When the reverse signal is input, the power is supplied to the
rear view camera, and then the image signal from the rear view
camera is sent to the front display unit.

The camera control unit displays the guiding lines and possible
route lines, and then it synthesizes them to the camera image.
CAN Communication System DescriptionNKS0048B
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Many elec-
tronic control units are equipped onto a vehicle, and each control unit shares information and links with other
control units during operation (not independent). In CAN communication, control units are connected with 2
communication lines (CAN H line, CAN L line) allowing a high rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads required data only.
CAN Communication UnitNKS0048C
Refer to LAN-50, "CAN System Specification Chart" .

DIAGNOSIS SYSTEM
Revision: 2007 April2007 M35/M45
DIAGNOSIS SYSTEMPFP:00000
Multifunction Switch Self-Diagnosis FunctionNKS0048T
It can check each switch ON/OFF (continuity) operation of centralized switches.
SELF-DIAGNOSIS MODE

Turn the ignition switch from OFF position to ACC position.
Within 10 seconds, press and hold BACK switch and switch
for 3 seconds or more. Then, when these switches are released,
the buzzer sounds, all indicators of multifunction switch turned
on, and self-diagnosis mode is started.

When each switch is pressed, the switch continuity can be
checked by sounding the buzzer.
CAUTION:
The hazard switch cannot be checked.
FINISHING SELF-DIAGNOSIS MODE

When the ignition switch is turned ON, self-diagnosis mode is canceled.
Multi AV System Diagnosis FunctionsNKS0048U

There are 2 diagnosis functions (On board diagnosis and diagnosis using CONSULT-II). It is necessary to
use them properly according to the condition. If the on board diagnosis starts, perform diagnosis with on
board diagnosis. If the on board diagnosis does not start (because the display is not displayed, the multi-
function switch operation is not activated, etc.), perform diagnosis using CONSULT-II.

At on board diagnosis, the AV (NAVI) control unit diagnosis function starts when multifunction switch oper-
ation and the AV (NAVI) control unit performs the diagnosis for each unit of system. Then, it displays the
results on the display.

At diagnosis using CONSULT-II, the AV (NAVI) control unit diagnosis function starts when the CAN com-
munication and the AV (NAVI) control unit perform the diagnosis for each unit of system.
On Board DiagnosisNKS0048V
DESCRIPTION

It has Self-Diagnosis mode for conducting trouble diagnosis automatically and a Confirmation/Adjustment
mode for operating manually.

Self-diagnosis mode diagnoses AV (NAVI) control unit and communication of each unit composing sys-
tem, and displays self-diagnosis results. NAVI control unit diagnoses communication with GPS antenna
simultaneously.

Confirmation/Adjustment mode is used to monitor the vehicle signals requiring operation and judgement
by a technician (malfunctions that cannot be automatically judged by the system), the confirmation/
change/adjustment of setting value, the error history of system, and the communication condition of sys-
tem.

by pushing “BACK” button.
Mode Description
Self Diagnosis

AV (NAVI) control unit diagnosis and connection diagnosis between
AV (NAVI) control unit and each unit

The DVD-ROM drive diagnosis of NAVI control unit and the connec-
tion diagnosis between NAVI control unit and GPS antenna can be
performed
(DVD-ROM drive will not be diagnosed when no map DVD-ROM is in
it.)
Confirmation/
AdjustmentDisplay DiagnosisThe tint can be confirmed by the color spectrum bar display. The shad-
ing of color can be confirmed by the gradation bar display.
Vehicle SignalsDiagnosis of signals can be performed for vehicle speed, parking brake,
lights, ignition switch, and reverse.
Speaker Test The connection of a speaker can be confirmed by test tone.

AdjustmentWhen there is a difference between the actual turning angle and the
vehicle mark turning angle, it can be adjusted.
Speed CalibrationWhen there is a difference between the current location mark and the

are displayed. When the malfunctioning item is selected, the time and
place that the selected malfunction last occurred are displayed.

Vehicle CAN Diagnosis The transmitting/receiving of CAN communication can be monitored.
AV COMM DiagnosisThe communication condition of each unit of Multi AV system can be
monitored.
