TELEMATICS TELEMATICS SYSTEM(for TOYOTA Connect) SYSTEM DESCRIPTION
TELEMATICS SYSTEM OUTLINE
The telematics system is a telematics service that links the vehicle and TOYOTA Connect network (provides information from the TOYOTA Connect Center or content providers).
In order for the user to use the TOYOTA Connect service, it is necessary to create a contract at the dealer and register the vehicle and user information.

Blinks in diagnostic mode to indicate a DTC. ·
Blinks in diagnostic mode to indicate a specific vehicle history. |
||
| Telephone Microphone Assembly | ·
When an emergency call is not being made: Sends the microphone voice signal to the radio and display receiver assembly. ·
When an emergency call is made: Sends the microphone voice signal to the telematics transceiver. |
||
| Navigation Antenna Assembly | ·
Sends and receives the data and voice signals used for the TOYOTA Connect via a communication network. ·
Receives GPS radio waves and sends them to the telematics transceiver. |
||
| Telematics Transceiver | ·
Uses the navigation antenna assembly to send and receive the data and voice signals used for the TOYOTA Connect via a communication network. -
When an emergency call is made: Sends the received voice signal to the vehicle speaker. -
When an emergency call is made: Receives the sent voice signal from the telephone microphone assembly. -
When an emergency call is made: Sends a mute signal to the radio and display receiver assembly. (Mute function becomes active during the call.) -
When an emergency call is made: Sends vehicle location information to the TOYOTA Connect Center. -
When the theft deterrent system is activated, the telematics transceiver sends information that the security horn has sounded to the TOYOTA Connect Center. -
Sends vehicle location information to the radio and display receiver assembly. -
Receives remote operation signals from the service center. |
||
| Mobilephone Battery (Back-up Battery) | ·
When an automatic emergency call is performed, the mobilephone battery provides power to the telematics transceiver. ·
When a manual emergency call is made, the mobilephone battery is not used as the power source. ·
The mobilephone battery conducts a self-diagnosis every time the ignition switch is turned to ON, and after an automatic emergency call or manual emergency call is made, and the result is sent to the telematics transceiver. |
||
| Air Conditioning Amplifier Assembly | ·
Operates the air conditioning system, based on signals from the telematics transceiver. ·
Sends ambient temperature signals to the telematics transceiver. |
||
| Main Body ECU (Multiplex Network Body ECU) | Sends a security horn sounding signal to the telematics transceiver when the theft deterrent system is activated. | ||
| Radio and Display Receiver Assembly | Sends and receives the data used for the TOYOTA Connect to and from the telematics transceiver using a telematics data signal.
·
When the operator service is used: Sends the sent voice signal from the telephone microphone assembly to the telematics transceiver. ·
When the operator service is used: Sends the received voice signal from the telematics transceiver to the vehicle speaker. |
||
| Airbag Sensor Assembly | Sends an activation signal to the telematics transceiver when airbags deploy. (An automatic emergency call is made.) | ||
| Combination Meter Assembly | Sends a warning signal to the telematics transceiver via CAN communication when a warning | ||
| Certification ECU (Smart Key ECU Assembly) | Receives the remote engine start and stop signal from the user's smartphone or electrical key transmitter sub-assembly via the telematics transceiver and initiates the engine start operation. | ||
DEVICE USED FOR TELEMATICS SYSTEM COMMUNICATION
The telematics transceiver is used for data communication or emergency call service telephone calls and operator service telephone calls.
The hands-free function does not use the telematics transceiver. A user's "Bluetooth" compatible cellular phone needs to be used.
Perform the following procedure if the device used for telematics system communication is replaced.
- HINT:
- ·
If the telematics transceiver is replaced on vehicles that do not have a contract for the TOYOTA Connect, perform vehicle contract setting.
·If the telematics transceiver is replaced on vehicles that have a contract for the TOYOTA Connect, perform the vehicle contract setting and the procedure to resume the TOYOTA Connect to start the emergency call service.
TELEMATICS TRANSCEIVER OUTLINE
On this model, the telematics transceiver functions as the TOYOTA Connect device.
| *a | Serial Number (IMEI) |
The telematics transceiver has a serial number (IMEI) which can be used to determine the individual device when servicing.
TOYOTA CONNECT SUPPORT CENTER OUTLINE
The TOYOTA Connect support center provides members with opportunities to ask questions and information necessary for troubleshooting.
| Main Service | Outline |
|---|---|
| Answering questions about the TOYOTA Connect | Answers questions from customers about the TOYOTA Connect |
| Contracting or canceling the TOYOTA Connect | Performs procedures to make or cancel a contract for customers |
| Confirming server or communication conditions | Confirms the TOYOTA Connect Center condition |
| Re-registering a TOYOTA Connect device | Performs procedures for re-registration when the TOYOTA Connect device is replaced |
| Answering questions about a manual maintenance check for the emergency call service | Answers questions when a manual maintenance check for the emergency call service has not completed normally |
COMMUNICATION SYSTEM
USB Outline
Telematics system components communicate with each other via USB communication.
- HINT:
-
If a short or open occurs in a USB communication line, communication will be interrupted and the system will not operate normally.
CAN Communication Outline
The telematics system uses CAN communication between the telematics transceiver and ECUs.
COMMUNICATION BASED VOICE RECOGNITION FUNCTION (w/ Navigation System)
There are two types of voice recognition; the voice recognition function uses voice recognition data stored in the onboard device. The other is communication based and uses voice recognition data sent from communication with the telematics transceiver as audio signals to be stored at the center.
- HINT:
-
Refer to the navigation system for information about voice recognition.
Communication Based Voice Recognition
By performing the voice recognition process at the center, natural language input and interactive voice operations besides the specified commands can be performed.
COMMUNICATION FUNCTION PAUSING
- NOTICE:
-
Before performing inspections or repairs which may cause warning messages to be displayed or DTCs to be stored, such as a simulation test or road test, it is necessary to enter communication function pausing mode so that unnecessary warning messages are not sent to the TOYOTA Connect Center.
Communication function pausing mode

Turn the ignition switch off.
Connect the GTS to the DLC3.
Start the engine.
Turn the GTS on.
Enter the following menus: Body Electrical / Telematics
- HINT:
- ·
