Accident involving activation of airbag and/or belt tensioner
NOTE:
- The airbag control module can be used for triggering the side airbags and/or belt-tensioners up to 3 times.
- The DTC display "Control Module Malfunctioning" will appear after third triggering.
Airbag control module must be replaced:
- If drivers/passenger side airbag has been triggered.
- If housing is damaged
- In the event of tunnel deformation within 200 mm radius of control module
- After airbag has been triggered three times
Always replace the following:
- All triggered airbag units
Also replace if passenger side airbag has been triggered:
- Airbag flap and frame (never bend deformed frame back into shape); instrument panel if damaged.
- Lateral acceleration sensor if floor pan around sensor has been deformed.
Also replace if drivers side airbag has been triggered:
- Coil connector with slip ring
- Lateral acceleration sensor if floor pan around sensor has been deformed.
Also replace if side airbag has been triggered:
- Lateral acceleration sensor on side where airbag has been triggered.
- Non-triggered lateral acceleration sensor if floor pan around sensor has been deformed.
Additionally:
- All seat belts with triggered belt tensioners
- Triggered belt tensioners can be identified using On Board Diagnostic (OBD).
A - If airbag control module has been triggered:
Front belt tensioner:
- Read measured value block, display group 001: Triggered belt tensioners can be seen from display "too large".
B - If airbag control module has been replaced:
- Check DTC memory : A triggered belt tensioner is identified by the DTC message "Belt tensioner igniter - Resistance value too large".
- In addition, all damaged components must also be replaced if necessary (visual check).
