Safety Components Following An Accident, Replacing

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).

Accident not involving activation of airbag
- If the Airbag Warning Light K75 does not indicate a malfunction, it is not necessary to replace the airbag/belt-tensioner components.

After replacing the airbag units or the control module, affix stickers (only tear-off strips) to the registration card and return the registration card to the warranty center for registration.
