NOTE:
The name MULTIFUNCTION SWITCH indicates the integration of PRESET SWITCH and MULTIFUNCTION
SWITCH virtually.
System DescriptionINFOID:0000000003791247
The audio system is equipped with following function. Each function can be operated with the multifunction
switch, preset switch, rear control switch or steering switch. It indicates the operation status of AUDIO to the
display unit.
FUNCTION DESCRIPTION
Operating Signal
Operation of the audio system can be performed via the multifunction switch, preset switch, rear control switch
or steering switch.
 Operating signal is transmitted to AV control unit via AV communication when it is operated by multifunction
switch, preset switch or rear control switch. The CD ejection operating signal is performed by hard-wire.
 Operating signal is transmitted to AV control unit with steering switch signal when it is operated by steering
switch.
Screen Display
 The display switching of the screen is performed by the communication signal between the display unit and
the AV control unit.
 The image signal to display operating condition is performed by RGB image signal, RGB area signal and
RGB image synchronizing signal.
AM/FM Radio Mode
 AM/FM radio tuner is built into AV control unit.
 AM/FM radio wave is received by glass antenna, next it is amplified by antenna amp., and finally it is input to
AV control unit. The FM sub antenna is installed on the rear window glass and the AV control unit is
received.
 Sound signal is input to BOSE amp. and BOSE amp. outputs to woofer and each speaker for AV control unit.
CD Mode
 CD function is built into AV control unit.
 AV control unit outputs sound signal to BOSE amp. and BOSE amp. outputs to woofer and each speaker
when CD is inserted to AV control unit.

STARTING PROCEDURE
1. Start the engine.
2. Turn the audio system OFF.
3. While pressing the “SETTING” button, turn the volume control
dial clockwise or counterclockwise for 40 clicks or more. (When
the self-diagnosis mode is started, a short beep will be heard.)
 Shifting from current screen to previous screen is performed
by pressing “BACK” button.
4. The trouble diagnosis initial screen is displayed, and then the
items of “Self Diagnosis” and “Confirmation/Adjustment” can be
selected.
SELF-DIAGNOSIS MODE
1. Start the self-diagnosis function and select “Self Diagnosis”.
- Self-diagnosis subdivision screen is displayed, and the self-diagnosis mode starts.
- The bar graph visible on the center of the self-diagnosis subdivision screen indicates progress of the trou-
ble diagnosis.

COMPONENT DIAGNOSIS
U1000 CAN COMM CIRCUIT
DescriptionINFOID:0000000003765661
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, CAN-L) allowing a high rate of information transmission with less wiring. Each
control unit transmits/receives data but selectively reads required data only.
