Auto SOS & roadside assistance call
In the event of an accident, the airbag control unit J234 deter-
mines the severity of the impact. Impacts are subdivided into 2
categories and communicated to the data bus diagnostic interface
J533 via the data bus system and a discrete cable.
In a category 1 impact, the online roadside assistance call is
activated automatically. A message is displayed on the MMI
screen. The user can now decide whether to call for roadside
assistance or to call the emergency number.
In a category 2 impact, an Auto SOS call is activated and a voice
call to the Audi Emergency Call Centre is initiated.
In both cases, the vehicle identification number, the location of the
vehicle and the last direction of travel are transmitted.
