Operation

Auto call operation

1.  If the vehicle is involved in a collision, the sophisticated airbag sensor (SAS) control module sends (1) a collision detection signal to the emergency call unit via CAN communication and hard wire.

2.  When the collision detection signal is received from the sophisticated airbag sensor (SAS) control module, the emergency call unit detects the following information based on a signal (2) from the related module.

•  Vehicle/accident information

―  Accident occurrence position information and accident occurrence time information received from TEL antenna

―  Vehicle model information and traveled distance (total traveled distance) received from body control module (BCM)

―  Powertrain information received from body control module (BCM)

3.  The emergency call unit sends (3) accident information/vehicle information to a call center via TEL antenna. In addition, the emergency call unit sends (4) an operation status notification signal to the emergency call speaker and the emergency call switch, and controls the activation of the notification sound and the illumination/flashing of the indicator.

4.  When the transmission of the accident information/vehicle information to the call center is completed or approx. 20 s have elapsed after starting to send the accident information/vehicle information, the emergency call unit starts the voice call (5) with the call center via the emergency call speaker/microphone.

a30zzn00001132

Manual call operation

1.  When the emergency call switch OFF signal is received (1) after receiving the emergency call switch ON signal for approx. 1 s or more, the emergency call unit detects (2) an emergency call request from the user.

2.  When the emergency call request is detected, the emergency call unit detects the following information based on a signal (3) from the related module.

•  Vehicle information

―  Vehicle position information and emergency call request occurrence time information received from TEL antenna

―  Vehicle model information and traveled distance (total traveled distance) received from body control module (BCM)

―  Powertrain information received from body control module (BCM)

3.  The emergency call unit sends (4) accident information/vehicle information to a call center via TEL antenna. In addition, the emergency call unit sends (5) an operation status notification signal to the emergency call speaker and the emergency call switch, and controls activation of the notification sound and the illumination/flashing of the indicator.

4.  When the transmission of the vehicle information to the call center is completed or approx. 20 s have elapsed after starting to send the vehicle information, the emergency call unit starts the voice call (6) with the call center via the emergency call speaker/microphone.

a30zzn00001133

Audio speaker mute operation

1.  When a collision detection signal is received or an emergency call request is detected, the emergency call unit sends (1) an audio output stop signal to the audio amplifier via CAN communication.

2.  When the audio output stop signal is received, the connectivity master unit stops (2) audio output.

3.  When the audio output is stopped, the audio amplifier sends an audio output stop completion signal (3) to the emergency call unit via CAN communication.

4.  When the audio output stop completion signal is received, the emergency call unit detects that stopping of the audio output is completed.

Note

•  If the audio output stop completion signal cannot be received, the emergency call unit cuts off the most circuit and forcefully stops audio output.

5.  The emergency call unit restores audio output after a voice call is finished.
