TELEMATICS SYSTEM SYSTEM DESCRIPTION


  1. DESCRIPTION


    1. ERA-GLONASS provides 2 services: Automatic Emergency Call and Manual Emergency Call.

      If the vehicle is involved in an accident, the telematics system will make an automatic emergency call to a Public Safety Answering Point (PSAP) and transmit the vehicle location, determined by a GNSS satellite, and vehicle information. After receiving an emergency call from the vehicle, depending on the situation, a PSAP operator may immediately contact emergency services.

  2. FUNCTION OF MAIN COMPONENTS

    Component Function

    Map Light Sub-assembly


    • Manual (SOS) Switch

    		 Sends a switch signal to the telephone transceiver assembly when pressed. (When a test call or manual emergency call is performed.)
    LED Indicator Light Green

    • Illuminates for 2 seconds after the engine switch is turned on (IG) and the manual (SOS) switch indicator (red) has illuminated for 10 seconds.

    • Turns on when the system is operating normally.

    • Blinks during an emergency call.

    • Blinks during test mode.

    • Blinks 5 times when entering test mode (the manual (SOS) switch indicator (green) blinks at the same time).
    Red

    • Illuminates for 10 seconds after the engine switch is turned on (IG).

    • Blinks when an emergency call has failed.

    • Turns off when the system is operating normally.

    • Illuminates when the mobilephone battery needs to be replaced.

    • Illuminates when the DTCs are stored.

    • Blinks 5 times when entering test mode (the manual (SOS) switch indicator (red) blinks at the same time).
    Telephone Microphone Assembly Sends the microphone voice signal to the telephone transceiver assembly.
    Navigation Antenna Assembly Receives GPS and GLONASS radio signals and sends them to the telephone transceiver assembly.
    Telephone Antenna Assembly Sends and receives data and voice signals used for emergency calls via a communication network.
    Telephone Transceiver Assembly

    • Uses the telephone antenna assembly to send and receive data and voice signals used for emergency calls via a communication network.


      • Sends the received voice signal to the vehicle speakers.

      • Receives the sent voice signal from the telephone microphone assembly.

      • Sends a mute signal to the stereo component amplifier assembly. (The audio system is automatically muted during an emergency call.)

      • Sends vehicle location information to the PSAP.

      • Conducts self-diagnosis every time the engine switch is turned on (IG) and after an automatic emergency call or manual emergency call is made.
    Mobilephone Battery

    • When an automatic emergency call is performed, provides power to the telephone transceiver assembly.

    • When a manual emergency call is made, is not used as the power source.
    Airbag ECU Assembly Sends an activation signal to the telephone transceiver assembly when the airbags deploy. (An automatic emergency call is made.)

  3. MAYDAY ID OUTLINE


    1. The telephone transceiver assembly functions as the emergency call service device to perform emergency calls.

    2. The telephone transceiver assembly has serial numbers (IMEI, ICCID) which can be used to identify the individual device when servicing.

      *a IMEI, ICCID

      The IMEI and ICCID are printed on the label attached to the telephone transceiver assembly.

  4. COMMUNICATION SYSTEM


    1. CAN Communication Outline


      1. The telematics system uses CAN communication between the telephone transceiver assembly and ECUs.

  5. DIAGNOSTIC FUNCTION OUTLINE


    1. The telematics system has a diagnostic function (the result will be displayed on GTS).
