Working On The Airbag System
WARNING: This page does not describe the selected car, but rather 18 other vehicles, including the 2016 Audi S4, 2016 Audi A4 Quattro, 2016 Audi A4, 2015 Audi S4, and 2015 Audi A4 Quattro. However, it is still accessible from the selected car via links, so may be relevant.
WARNING:
When working on the airbag system (pyrotechnic components, Airbag Control Module -J234-, wiring), the Ground (GND) cable must be disconnected with the ignition switched on.
Exceptions: On vehicles with a battery in the passenger compartment, the ignition must be switched off.
- Then cover the negative terminal.
- After disconnecting the battery, a wait time of 10 seconds is required.
- The battery must be connected with the ignition switched on.
- There must be no one inside the vehicle when connecting the battery.
Make sure in this case to keep oneself away from the airbag deployment and belt tensioner zones.
If the ignition is not switched on after reconnecting the battery (the indicator lamps in the instrument cluster do not illuminate), the ignition (key/button) may only be switched on while sitting in the driver's seat in the rearmost position.
