RELATED TO HANDS FREE PHONE
Check that the cellular phone is corresponding type (Bluetooth® enabled) when the hands free related mal-
function vehicle is in service before performing a diagnosis.
There is a case that malfunction occurs due to the version change of the phone type, etc. even though it is a
corresponding type. Therefore, confirm it by changing the cellular phone to another corresponding type
phone, and check that it operates normally. It is necessary to distinguish whether the cause is the vehicle or
cellular phone. Check to ensure the customers phone is supported by checking the phone compatibility for
the hands free system.

MULTI AV SYSTEM
FUNCTION DIAGNOSIS
MULTI AV SYSTEM
System DiagramINFOID:0000000001728627
System DescriptionINFOID:0000000001728628
Multi AV system means that the following systems are integrated.
Two AV communication lines (H, L) connect between units that configure MULTI AV system. NAVI control
unit controls by sending/receiving data one by one with each unit (slave unit) that configures them com-
pletely as a master unit.
Two AV communication lines (H, L) adopt a twisted pair line that is resistant to noise.
NAVI 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. Sending/
receiving of data signal is performed by BCM. Also, it sends the required signal of vehicle setting and
receives the response signal.

COMPONENT DIAGNOSIS
U1000 CAN COMM CIRCUIT
DescriptionINFOID:0000000001728646
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.

NAVI CONTORL UNIT Map data can be read from the map DVD-ROM by installing map DVD-ROM.
It is the master unit of the MULTI AV system, and it is connected to each control
unit by means of communication. It operates each system according to com-
munication signals from the NAVI control unit.
The NAVI control unit includes the audio, hands-free phone, navigation, and
vehicle information functions.
It is connected to ECM and combination meter via CAN communication to ob-
tain necessary information for the vehicle information function.
It inputs the illumination signals that are required for the display dimming con-
trol.
It inputs the signals for driving status recognition (vehicle speed, reverse and
parking brake).
