FOR MEXICO : Precautions for Removing of Battery Terminal
INFOID:0000000010137955
• When removing the 12V battery terminal, turn OFF the ignition
switch and wait at least 30 seconds.
NOTE:
ECU may be active for several tens of seconds after the ignition
switch is turned OFF. If the battery terminal is removed before ECU
stops, then a DTC detection error or ECU data corruption may
occur.
• For vehicles with the 2-batteries, be sure to connect the main bat-
tery and the sub battery before turning ON the ignition switch.
NOTE:
If the ignition switch is turned ON with any one of the terminals of
main battery and sub battery disconnected, then DTC may be
detected.
• After installing the 12V battery, always check "Self Diagnosis Result" of all ECUs and erase DTC.
NOTE:
The removal of 12V battery may cause a DTC detection error.

INFOID:0000000009721712
AV COMMUNICATION SYSTEM
• Do not apply voltage of 7.0 V or higher to the measurement terminals.
• Use the tester with its open terminal voltage being 7.0 V or less.
• Be sure to turn ignition switch OFF and disconnect the battery cable from the negative terminal before
checking the circuit.
FOR MEXICO : Precaution for Harness Repair
INFOID:0000000009721713
AV COMMUNICATION SYSTEM
• Solder the repaired parts, and wrap with tape. [Frays of twisted line
must be within 110 mm (4.33 in).]
• Do not perform bypass wire connections for the repair parts. (The
spliced wire will become separated and the characteristics of
twisted line will be lost.)

Description
AV control unit
• It is the master unit of the MULTI AV system, and it is connected to each control
unit by communication. It operates each system according to communication
signals from the AV control unit.
• The AV control unit includes the audio, rear view monitor, USB connection and
vehicle information functions.
• It is connected to ECM and combination meter via CAN communication to obtain
necessary information for the vehicle information function.
• It is connected to BCM via CAN communication transmitting/receiving for the ve-
hicle settings function.
• It inputs the illumination signals that are required for the display dimming control.
• It inputs the signals for driving status recognition (vehicle speed, reverse and
parking brake).
• It supplies power to the rear camera.
• Amp. ON signal and sound signal are transmitted to BOSE amp.
• TEL voice signal is input from TEL adapter unit.
Display unit
• Display image is controlled by the serial communication from AV control unit.
• It receives the power (signal VCC and inverter VCC) from the AV control unit and
operates.
