2) Wait for 10 seconds after disconnecting the battery
REV: 11/2017
PARTS THAT MUST BE REPLACED FOLLOWING A DEPLOYMENT
Restraint System Components, 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 [deployed] airbag units [AIRBAG,STEERING WHEEL; AIRBAG,KNEE BOLSTER; AIRBAG,INSTRUMENT PNL; AIRBAG,FRONT SEAT; AIRBAG,REAR SEAT; AIRBAG,ROOF]
• The battery interrupt igniter -N253• [IGNITER,BATTERY INTERRUPT]
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 [AIRBAG SENSOR,FRT DOOR; AIRBAG SENSOR,QTR PANEL]
Also with Driver airbag deployment:
• Coil connector with slip ring
• 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]
• Seat 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; AIRBAG SENSOR,QTR PANEL]
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
Test the system with a suitable vehicle tester. After an accident, all damaged parts must be replaced.Passenger Occupant Detection System Deactivation After a Collision:
•Each time an airbag or passenger belt deploys, a basic setting must be performed on the seat occupied recognition control module.
• 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 "passive
occupant detection system service kit"
Active headrests:
Active headrests that have been fired 25 times have to be replaced.
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.
Seat belt system:
• Connect the Vehicle Diagnostic Tester if there is a chance the belt tensioner and/or seat belt force limiter deployed
• Seat belts, including child seat anchorages and hardware and mounting points
Airbag Mounting Components, Checking after an Accident. 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
With a Driver Airbag Deployment:
• Steering wheel
If needed (visual inspection), the following must also be replaced: all faulty components.
