PARTS THAT MUST BE REPLACED FOLLOWING A DEPLOYMENT
If the seat rails and/or seat pan is replaced after an accident due to deformations resulting from a crash, the passenger occupant detection system must be replaced using the “passenger occupant detection system service kit”.Always Replace the Following:
• All deployed airbag units [AIRBAG,STEERING WHEEL; AIRBAG,INSTRUMENT PNL; AIRBAG,KNEE BOLSTER; AIRBAG,FRONT SEAT, AIRBAG,ROOF]
Also with Front Passenger Airbag Deployment:
• Instrument Panel
• Deformed front passenger module supports (cannot be reformed)
• All sensors for front airbag on the front end [AIRBAG SENSOR,FRONT]
• Remaining transverse acceleration sensors if the mounting points are deformed in the sensor area
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
Also with Side Airbag Deployment:
• Pressure sensors on the deployed side [AIRBAG SENSOR,FRT DOOR, AIRBAG SENSOR,QTR PANEL]
• Transverse acceleration sensors on the deployed side
• Cover
• Cushion
• With a folding rear seat backrest: side cushion (if equipped)
• Remaining cross acceleration sensors if anchorage point is
deformed in sensor region. [AIRBAG SENSOR,FRONT; AIRBAG SENSOR,QTR PANEL]
Also:
• All automatic belt retractors with deployed belt tensioners.
• All automatic belt retractors with deployed seat belt force limiters (depending on vehicle 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
The Battery Interrupt Igniter • N253• interrupts the electrical circuit each time an airbag is deployed. The Battery Interrupt Igniter • N253• must be replaced after a deployment.
PARTS THAT MUST BE INSPECTED AND REPLACED IF DAMAGED
The Airbag Control Module Must be Replaced:• If the display “Control module faulty” appears after checking the Diagnostic Trouble Code (DTC) memory
•After three side/driver/front passenger airbag or belt tensioner deployments
• if housing is damaged
• if there is deformation on the tunnel within a 200 mm radius around the control module
Connect the Vehicle Diagnostic Tester if there is a chance the belt tensioner and/or seat belt force limiter deployed.
• Check the seat belts
• If parts of the seat belt system are removed due to an accident, replace the belt system bolts.
If needed (visual inspection), the following must also be replaced:
• All faulty components.
• All damaged parts must be replaced after a collision. If no
airbag unit damage is detected, the airbag unit can still be
used.
• After replacing control module, it must be coded using the Vehicle Diagnostic Tester .
The following components must be checked after every airbag deployment.
With Front Passenger Airbag Deployment:
• Instrument panel central tube; front passenger airbag supports and passenger airbag unit must be installed free of tension. Otherwise the central tube is to be replaced.
• Check the glove compartment for damage. Replace the glove compartment if damaged.
With Driver Airbag Deployment:
• Steering wheel
• Check steering wheel for smoke residue. If smoke residue is present, replace the steering wheel.
WARNING:
After every accident the seat belt system must be inspected systematically.
