Av Control Unit

AV Control Unit

• A 8-inch color display with multi-touch control, an AM/FM/HD electronic tuner radio with RDS and camera controller are integrated into the AV Control unit.

  

• The 8-inch color display is a high resolution monitor that includes touch panel functions.

Tcu

TCU

• Telematics Communication Unit (TCU) is installed in RH side of instrument panel behind the glove box.

  

• A radio communication terminal and SIM card are built into the unit and data is sent and received in SMS^*, DTMF tone signal with the NissanConnect^® center through the TEL antenna.

  Note:

  *: SMS stands for Short Message Service. It is also referred to as Text Messaging, Short Mail, etc. is the service that performs text based message communication.

• It is connected to the AV control unit with the USB harness for sound signal input/output and USB communication.

• It is connected to the air bag diagnosis sensor unit via CAN communication. TCU performs an emergency report when the air bag is inflated.

• VIN information necessary for the Telematics service is memorized.

• Audio signals received during SOS/Operator call are transmitted from TCU to each speaker via the AV control unit.

• During the communication with NissanConnect center, TCU transmits a TEL ON signal to the AV control unit to prohibit the use of Bluetooth^® hands-free phone.

Telematics Antenna

Telematics Antenna

• The telematics antenna consists of TEL antenna and GPS antenna.

• It is installed in the instrument panel.

  Note:

  The placement of an object on the instrument panel may cause desensitization in the receiver sensitivity.

Telematics Switch

Telematics Switch

• The moonroof switch assembly (telematics switch) is located on the map lamp assembly.

  

• The moonroof switch assembly (telematics switch) is connected to TCU and transmits an operation signal.

• The state of LED (ON/Blink/OFF) shows the status of SOS call.

  LED ON	:SOS Call available
  LED Blink	:SOS Call in communication
  LED OFF	:Out of service area or system error

Microphone

Microphone

• Microphone is installed on the map lamp assembly.

  

• The microphone is used for the operation of the NissanConnect, hands-free phone system, voice recognition function.

• The power is supplied from the TCU to the microphone, transmitting sound signals to the TCU during operation of the NissanConnect system, hands-free phone communication, and voice recognition.

TCU Input Signal (CAN Communication)

Transmit unit	Signal name
Air bag diagnosis sensor unit	Air bag crash order signal
ABS actuator and electrical unit (control unit)	ABS malfunction signal
BCM	Door switches state signal
Combination meter	Nissan Sentra Vehicle speed signal Hand brake switch signal
ECM	Engine RPM signal MIL lamp signal
IPDM E/R	Anti-theft horn status signal
TCM	Transmission range indication signal

DESCRIPTION

• The Telematics system is a system for providing information by connecting the Nissan Sentra vehicle and the user to the NissanConnect center.

• Telematics Communication Unit (TCU) equipped with a radio communication terminal communicates with the information center (NissanConnect center) via radio waves for receiving NissanConnect services.

• With the equipment of the radio communication terminal, TCU communicates with NissanConnect center by Packet communication^*1 and SMS^*2 via TEL antenna.

  Note:

  • *1: Packet communication means a communication method that data is broken down into smaller chunks for communication. The split data is called a packet and improves the efficiency of the communication circuit.

  • *2: SMS stands for Short Message Service, also known as text messaging or short mail, and provides text-based message communication services.

• While communicating with the operator, data (e.g. transmission of own Nissan Sentra vehicle location) is transmitted to the NissanConnect Service Center by using DTMF tone signals and SMS via the radio communication module included in TCU.

• Audio signals transmitted and received while communicating with the operator are input by microphone connected to TCU.

• Audio signals are output from TCU via the audio data circuit connected to the AV control unit.

CONFIGURATION

Configuration has the three following functions:

Function		Description
Read/Write Configuration	Before Replace ECU	Allows storage of the Nissan Sentra vehicle specification written in TCU to the CONSULT.
	After Replace ECU	Allows writing of the Nissan Sentra vehicle specification stored in CONSULT to the TCU.
Manual Configuration		Allows writing of the Nissan Sentra vehicle specification to the TCU manually.

CAUTION:

• When replacing TCU, you must perform “Read / Write Configuration” or “Manual Configuration” with CONSULT.

• Complete the procedure of “Read / Write Configuration” or “Manual Configuration” in order.

• If you set incorrect “Read / Write Configuration” or “Manual Configuration”, incidents might occur.

• Configuration is different for each Nissan Sentra vehicle model. Confirm configuration of each vehicle model.
