Occupant safety
Passive safety
Airbag Control Module J234 has been enhanced for the
occupant protection system in the 2017 Audi Q7. It houses
a sensor which now measures around the Z axis of the
vehicle.
Communication with other control modules is now done
via the FlexRay data bus. This allows for example, the ABS
control module to receive real time data about vehicle
rotation around the Z axis that is utilized by the Electronic
Stability Control (ESC) system.
Active safety
Four Audi pre-sense functions are available for the Audi Q7.
In addition to Audi pre-sense basic, these are:
• presenserear.
• presensefront.
• presensecity.
Audi pre sense city warns the driver about vehicles and
pedestrians and brake within system limitations. Audipre
sense front brings to the Audi Q7 new functions such as
evasion assist and turn assist.
Learning objectives of this Self Study Program:
Once you have completed this Self-Study Program you will
be able to answer questions on the following topics:
• New passive safety features.
• New active safety features.
• Modications to and new features of the infotainment
system.

Infotainment
Audi oers various levels of the infotainment modules for
the AudiQ7. MMIRadioplus is standard. This oers inter-
faces for external devices such as mobile phones or
memory cards. The Audi sound system delivers excellent
sound quality from its ten speakers.
MMI navigation plus also includes the feature Audi connect,
which connects the Audi Q7 to the Internet via the LTE
standard. Rear passengers can surf via the WiFi hotspot
with download speeds of up to 100 Mbit/s and send and
receive e-mail. The driver can use the customized Audi
connect services ranging from online trac information to
navigation with Google Earth and Google Street View to
online media streaming.

Center Crash Sensor for X/Y Axis G858
Center Crash Sensor for X/Y Axis G858 is for measuring the
movement (both acceleration and de-acceleration) of the
vehicle along the X/Y axes.
It is used to validate the plausibility of dened crash situations.
Installation location
It is located on the center body tunnel near the cross
member of the driver’s seat.

Airbag Control Module J234
Sensors and data bus interface
The airbag control module for the Q7 has undergone
extensive modication.
Sensors that measure acceleration in the X and Y directions
and the yaw rate around the vehicle’s Z axis (inertial
sensors) are now installed in Airbag Control Module J234.
J234 is now connected to the FlexRay bus to help ensure a
minimum reaction time of approximately 2ms in the event
of a crash.
Airbag Control Module J234 records and provides body
movement data to ABS Control Module J104 (as well as
other modules). J104 processes this information and initi-
ates the appropriate action regarding all ESC functions.
