What is Apple Car Crash Detection?

Apple Car Troubleshooting, officially referred to simply as Troubleshooting, is a security feature announced in 2022 for the recent iPhone and Apple Watch. Troubleshooting is built into iOS 16 and watchOS 8 and is enabled by default on supported devices.

The user can then swipe the screen over the screen emergency call Toggle to activate a call to emergency services or select Eliminates to stop working.


If no user interaction is detected after 10 seconds, the Apple device will automatically initiate a call to emergency services, play a voice message from Siri explaining the situation, and also communicate your location using latitude, longitude, and search range information. The call to emergency services will stop when the user chooses Stop recorded messages On the screen of your iPhone or Apple Watch, or when the call is separated from the other party. The process will then be repeated with one of your emergency contacts.


How does troubleshooting work on iPhone and Apple Watch?

Apple Troubleshooting works by using a combination of a gyroscope, accelerometer, barometer, GPS, and microphone to process physical inputs that could indicate a significant impact.

Fault detection is designed to detect frontal, rear, side impact and rollover impacts, and should not be triggered when the device is impacted or dropped. Troubleshooting can only work with your Apple Watch or iPhone, but it’s also optimized to work when both devices are present. For example, the feature will display more information on the Apple Watch screen instead of the iPhone when both are in use as the smartwatch will likely be closer to the user than the smartphone when a serious accident occurs.
