- When an accident occurs under specified conditions, the SAS control module sends a crash signal to the connectivity master unit (CMU).
- When the connectivity master unit (CMU) receives the crash signal from the SAS control module, it sends the guidance audio signal to the audio amplifier. In addition, it sends the Automatic 911 dialing screen display signal (GMSL signal) to the center display.
- The audio amplifier sends the guidance audio signal to the speakers and the speakers output the guidance audio. In addition, the center display displays the Automatic 911 dialing screen.
- The connectivity master unit (CMU) executes the 10 s timer after the guidance audio output.
- After 10 s have elapsed on the timer, the connectivity master unit (CMU) sends an outgoing call signal to a mobile device such as a Bluetooth ® enabled mobile phone or a Smartphone.
- When the mobile device, such as a Bluetooth ®-enabled mobile phone or a Smartphone, receives the outgoing call signal, it calls the PSAP (Public Safety Answering Point).
- After connecting to the PSAP (Public Safety Answering Point), the connectivity master unit (CMU) outputs the vehicle position information from the vehicle speakers and initiates the call.
