PARTS THAT MUST BE REPLACED FOLLOWING A DEPLOYMENT

• If the seat rails and/or the seat pan must be replaced after a accident due to deformation, the seat occupied recognition must also be replaced with the "seat occupied repair kit"

Airbag Units, Removing and Installing After an Accident:

The airbag control module must be replaced [MODULE,AIRBAG CONTROL]:
1) With driver and passenger airbag deployment "but not with airbag generation 9.•, 10.• and 8.R."
2) After three side airbag, driver airbag, passenger airbag or belt tensioner deployments
3) If housing is damaged
4) If there is deformation on the tunnel in 200 mm circumference around control module

Always replace the following:
• All triggered airbag units [AIRBAG,STEERING WHEEL; AIRBAG,INSTRUMENT PNL; AIRBAG,FRONT SEAT; AIRBAG,REAR SEAT; AIRBAG,ROOF]
• The battery interrupt igniter -N253• [IGNITER,BATTERY INTERRUPT ]
• Damaged securing pieces

Also with passenger airbag deployment:
• Instrument Panel
• Deformed passenger module supports (cannot be reformed)
• All sensors for front airbag on front end [AIRBAG SENSOR,FRONT]
• Remaining cross acceleration sensors if anchorage point is deformed in sensor region

Also with Driver airbag deployment:
• Coil connector with slip ring [CLOCK SPRING]
• All sensors for front airbag on front end [AIRBAG SENSOR,FRONT]
• Remaining cross acceleration sensors if anchorage point is deformed in sensor region

Also with side airbag deployment:
• Pressure sensor on deployed side [AIRBAG SENSOR,FRT DOOR]
• Cross acceleration sensors on deployed side [AIRBAG SENSOR,QTR PANEL]
• Cover
• Cushion
• With a folding rear seat backrest: side cushion (if equipped)
• Remaining cross acceleration sensors if anchorage point is deformed in sensor region
• Always replace the backrest upholstery if the side airbag deploys

In Addition:
• All belt retractors with deployed belt tensioners
• All belt retractors with deployed belt force limiters (depending on equipment)
• Seat belt latches for all automatic belt retractors with deployed seat belt tensioners with the belt on.
• Seat belt height adjuster (manual and power) for all automatic belt retractors with deployed seat belt tensioners with the belt on.

PARTS THAT MUST BE INSPECTED AND REPLACED IF DAMAGED

Test the system with a suitable vehicle tester

Each time an airbag or passenger belt tensioner deploys, a basic setting must be performed on the seat occupied recognition control module using the Vehicle diagnostic tester.

• If needed (visual inspection), the following must also be replaced: all faulty components
• The airbag control module can be used for up to 2 side airbag and/or belt tensioner deployments with airbag generation 8.•, except 8.R.
• The airbag control module can be used for up to two side driver and passenger airbag and/or belt tensioner deployments with airbag generation 9.•, 10.• and 8.R.
• After the third deployment, the malfunction display "Control module defect" appears.
• Seat belts and seat belt mounting points

The following components must be checked after every airbag deployment:

With a passenger airbag deployment:
• Instrument panel central tube, passenger airbag supports and passenger airbag must be installed free of tension. Replace central tube.
• Check the glove compartment for damage. Replace the glove compartment if damaged All damaged securing pieces must be replaced

With a driver airbag deployment:
