MULTI AV SYSTEM
 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-434, "
CONSULT-III Function (MULTI AV)".
 On board self diagnosis: Refer to AV-419, "
Diagnosis Description".
HANDS-FREE PHONE SYSTEM
 Hands-free communication can be operated by connecting using Bluetooth™ communication with cellular
phone.
 Operation is performed by display unit (touch panel), multifunction switch or steering switch, and operating
condition is indicated on display unit.
When a call is originated
Spoken voice sound output from the microphone (Mic. Signal) is input to NAVI control unit. NAVI control unit
outputs to cellular phone via TEL antenna with Bluetooth
™ communication as a TEL voice signal. Voice sound
is then heard at the other party.
When receiving a call
Voice sound is input to own cellular phone from the other party. The cellular phone outputs the voice signal to
TEL antenna by establishing Bluetooth
™ communication. The signal from TEL antenna is sent to front speaker
via NAVI control unit, AV control unit, and BOSE amp.
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.

RELATED TO BASIC OPERATION
RELATED TO HANDS FREE PHONE
 Check that the cellular phone is corresponding type (Bluetooth™ correspond) when the hands free related
malfunction 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.
Simple check for Bluetooth™ communication
If cellular phone and NAVI control unit cannot be connected with Bluetooth™ communication, following proce-
dure allows the technician to judge which device has malfunction.
1. Turn on a cellular phone, not connecting Bluetooth
™ communication.
2. Start CONSULT-III, then start Windows
®.
3. Set CONSULT-III near a cellular phone.
4. When operated Bluetooth
™ registration by cellular phone, check
if CONSULT-III
* would be displayed on the device name.
(If other Bluetooth
™ device is located near cellular phone, a
name of the device would be displayed also.)
NOTE:
*:Displayed device name is “NISSAN- ”.
 If no device name is displayed, cellular phone is malfunction.
Repair the cellular phone first, then perform diagnosis.
 If CONSULT-III is displayed on device name, cellular phone is nor-
mal. Perform diagnosis as per the following table.

COMBINATION SWITCH READING FUNCTION
Description
 BCM reads the status of the combination switch at 10 ms interval normally.
NOTE:
BCM reads the status of the combination switch at 60 ms interval when BCM is controlled at low power con-
sumption mode.
 BCM operates as follows and judges the status of the combination switch.
- INPUT 1 - 5 outputs the voltage waveforms of 5 systems simultaneously.
- It operates the transistor on OUTPUT side in the following order: OUTPUT 5 → 4 → 3 → 2 → 1.
- The voltage waveform of INPUT corresponding to the formed circuit changes according to the operation of
the transistor on OUTPUT side if any (1 or more) switches are ON.
- It reads this change of the voltage as the status signal of the combination switch.
Operation Example
In the following operation example, the combination of the status signals of the combination switch is replaced
as follows: INPUT 1 - 5 to “1 - 5” and OUTPUT 1 - 5 to “A - E”.
Example 1: When a switch (TURN RH switch) is turned ON
INPUT 4 — INT VOLUME 3 AUTO LIGHT — TAIL LAMP
INPUT 5 INT VOLUME 2 — RR FOG FR FOG —System OUTPUT 1 OUTPUT 2 OUTPUT 3 OUTPUT 4 OUTPUT 5
