FUNCTION DIAGNOSIS
MULTI AV SYSTEM
System DiagramINFOID:0000000003765641
NOTE:
 The name MULTIFUNCTION SWITCH indicates the integration of PRESET SWITCH and MULTIFUNCTION
SWITCH virtually.
 A radio antenna base integrated with radio antenna amp. is adopted.
 Woofer illustrated in the above figure, integrates two woofers and a woofer amp.
System DescriptionINFOID:0000000003791244
Multi AV system means that the following systems are integrated.
 AV control unit controls by transmitting/receiving data 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, 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 display unit and serial communication, and it transmits the required signal
of display and display control and receives the response signal from display unit.
NOTE:
AV control unit can perform CONSULT-III self-operating function and on board self-diagnosis.
 CONSULT-III self diagnosis: Refer to AV- 2 11 , "
CONSULT-III Function (MULTI AV)".
 On board self diagnosis: Refer to AV-200, "
Diagnosis Description".
DVD ENTERTAINMENT SYSTEM
 DVD player is connected with AV control unit via AV communication, and controlled by AV control unit.
 DVD image signal is output from DVD player to display unit via AV control unit.
 DVD stereo (2ch) sound signal is output from DVD player to each speaker via AV control unit and BOSE
amp.
 DVD surround (5.1ch) sound signal is output from DVD player to each speaker via BOSE amp.
 Operation can be performed with multifunction switch, steering switch and rear control switch. Multifunction
switch and rear control switch transmits operation signal to AV control unit by AV communication.
AUXILIARY INPUT SYSTEM
 Image and sound can be output from an external device by connecting a device with auxiliary input jacks.
 Operation can be performed with multifunction switch, steering switch and rear control switch. Multifunction
switch and rear control switch transmits operation signal to AV control unit by AV communication.
