REV: 07/2014
PARTS THAT MUST BE REPLACED FOLLOWING A DEPLOYMENT
Airbag control module must be replaced [MODULE,AIRBAG CONTROL]:• With driver and passenger airbag deployment "but not with airbag generation 9.•, 10.• and 8.R"
• After three side airbag, driver airbag, passenger airbag or belt tensioner deployments
Always replace the following:
• All triggered airbag units [AIRBAG,STEERING WHEEL; AIRBAG,KNEE BOLSTER; AIRBAG,INSTRUMENT PNL; AIRBAG,FRONT SEAT]
• The battery interrupt igniter -N253 [IGNITER,BATTERY INTERRUPT]
Also with passenger airbag deployment [AIRBAG,INSTRUMENT PNL]:
• 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 [AIRBAG SENSOR,FRT DOOR]
Also with driver airbag deployment [AIRBAG,STEERING WHEEL]:
• 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 [AIRBAG SENSOR,FRT DOOR]
Also with side airbag deployment:
• Pressure sensors on deployed side [AIRBAG SENSOR,FRT DOOR]
• Cross acceleration sensors on deployed side [AIRBAG SENSOR,FRT DOOR]
• 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,FRT DOOR]
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
• Seat belt height adjuster (manual and power) for all automatic belt retractors with deployed seat belt tensioners
PARTS THAT MUST BE INSPECTED AND REPLACED IF DAMAGED
Passenger Occupant Detection System, Procedure after an Accident:• Each time an airbag or passenger belt tensioner deploys, a basic setting must be performed on the seat occupied recognition control module
• If the seat rails and/or seat pan is replaced after an accident due to deformations resulting from a crash, the passive occupant detection system must be replaced using the "passive occupant detection system service kit". Then, perform the "basic setting" of the passive occupant detection system.
Airbag control module:
• 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
Airbag control module must be replaced [MODULE,AIRBAG CONTROL]:
• With driver and passenger airbag deployment “but not with airbag generation 9.•, 10.• and 8.R“
• After three side airbag, driver airbag, passenger airbag or belt tensioner deployments
• If housing is damaged
• If there is deformation on tunnel in 200 mm circumference around control module
Seat belt system
• seat belts
• Connect the Vehicle Diagnostic Tester if there is a chance the belt tensioner and/or seat belt force limiter deployed
• Child seat anchors must be checked for damage or deformation after an accident
With a passenger airbag deployment:
• Instrument panel center tube; make sure the front passenger airbag module and supports can be installed without tension. Otherwise, replace the center tube.
• Check the glove compartment for damage. Replace the glove compartment if damaged.
With a driver airbag deployment:
• Steering wheel: Remove the steering wheel and place it on the flat surface with the steering wheel rim. The entire rim must rest on the surface. Otherwise replace the steering wheel.
• Check the steering wheel for smoke residue and replace if there is any.
• If needed (visual inspection), the following must also be replaced: all faulty components
