PARTS THAT MUST BE REPLACED FOLLOWING A DEPLOYMENT

Airbag Units, Removing and Installing After an Accident:

Airbag control module must be replaced [MODULE,AIRBAG CONTROL]:
• If the display Control module faulty appears after check-
ing the DTC memory
• With driver and passenger airbag deployment “but not with airbag generation 9.•, 10.• and 8.R
• After three side/ driver/ front passenger airbag or belt tensioner deployments

Always replace the following:
• All deployed airbag units [AIRBAG,STEERING WHEEL, AIRBAG,INSTRUMENT PNL, AIRBAG,FRONT SEAT, AIRBAG,ROOF]

Also with front passenger airbag deployment:
• Instrument Panel
• Deformed supports of the front passenger airbag unit (cannot be reformed)
• All front airbag sensors on the front end [AIRBAG SENSOR,FRONT]
• Remaining transverse acceleration sensors if the mounting
points are deformed in the sensor area [AIRBAG SENSOR,FRT DOOR, AIRBAG SENSOR,QTR PANEL]

Also with driver airbag deployment:
• Return Spring with Slip Ring [CLOCK SPRING/LVR,STRG]
•All front airbag sensors on the front end [AIRBAG SENSOR,FRONT]
• Remaining transverse acceleration sensors if the mounting
points are deformed in the sensor area [AIRBAG SENSOR,FRT DOOR, AIRBAG SENSOR,QTR PANEL]

Also with side airbag deployment:
• Pressure sensors on deployed side [AIRBAG SENSOR,FRT DOOR]
• Transverse acceleration sensors on the deployed side [AIRBAG SENSOR,QTR PANEL]
• Cover
• Cushion
• with a folding rear seat backrest: side cushion (if equipped)
• Remaining transverse acceleration sensors if the mounting
points are deformed in the sensor area

In addition:
• All automatic belt retractors with deployed belt tensioners
• All automatic belt retractors with deployed seat 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

• After an accident, all damaged parts must be replaced
• After every accident the seat belt system must be inspected systematically
• Connect the Vehicle Diagnostic Tester if there is a chance the belt tensioner and/or seat belt force limiter deployed

The following components must be checked after every airbag deployment.

With a front passenger airbag deployment:
• Instrument panel crossmember; front passenger airbag sup-ports and passenger airbag unit must be installed free of
tension. Otherwise the crossmember is to be replaced.
• Check the glove compartment for damage. Replace the glove compartment if damaged.

With a driver airbag deployment:
• Steering wheel
• Check steering wheel for smoke residue. If smoke residue is present, replace the steering wheel.

Airbag control module must be replaced:
• The airbag control module can be used for up to two deployments of the side, driver and passenger airbag and/or belt tensioner with airbag generation 8.• not 8.R.
• The airbag control module with airbag generation 9.•, 10.• and 8.R. can be used for up to two side, driver and front passenger airbag and/or belt tensioner deployments
• After the third deployment, Control module faulty appears
in the display.
• If housing is damaged
• If there is deformation on tunnel in 200 mm circumference around control module

Also with passenger occupant detection system:
• Each time the front passenger airbag and/or belt tensioner on the front passenger side is deployed, the Passenger Occupant Detection System Control Module • J706• basic setting must be performed using the Vehicle Diagnostic Tester.
• If the seat rail and/or the seat pan are replaced due to defor-mations, then a basic setting must be performed on the Pas-senger Occupant Detection System Control Module • J706using the Vehicle Diagnostic Tester.

If needed (visual inspection), the following must also be replaced: all faulty components.
