Component Exchange After Airbag/Seat-Belt Pretensioner Triggering
WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2018 Porsche Cayenne, 2017 Porsche Cayenne, 2016 Porsche Cayenne, 2015 Porsche Cayenne, and 2014 Porsche Cayenne. However, it is still accessible from the selected car via links, so may be relevant.
The following components must be removed and replaced after the airbag system is triggered:
Airbag unit, driver's side:
- Airbag unit on driver's side.
- Contact unit.
- Triggering unit after the system is triggered for the third time.
- Airbag sensors: see below → 1.→ 2.
Airbag unit, passenger's side:
- Airbag unit, passenger's side.
- Dashboard.
- Check dashboard bracket for deformation and replace if necessary.
- Triggering unit after the system is triggered for the third time.
- Airbag sensors: see below → 1.→ 2.
Side airbag unit, seat:
- Side airbag unit, seat.
- Seat covering, deformed seat components.
- Triggering unit after the system is triggered for the third time.
- Airbag sensors: see below → 1.→ 2.
Head airbag unit:
- Head airbag unit.
- Replace roof lining.
- Airbag sensors: see below → 1.→ 2.
- Triggering unit after the system is triggered for the third time.
Knee airbag on driver's side:
- Trim panel under dashboard with knee airbag on driver's side.
- Airbag sensors: see below → 1.→ 2.
- Triggering unit after the system is triggered for the third time.
Airbag sensor:
- All airbag sensors in damaged/deformed areas of the vehicle must always be replaced.
- Otherwise (i.e. even if the vehicle was not crashed), the airbag sensors must be replaced if they show signs of mechanical damage and/or if the airbag control unit detects that the airbag sensor is defective (use PIWIS Tester II 9818 to read out the fault memory).
- Triggering unit after the system is triggered for the third time.
Seat-belt pretensioners:
- All seat-belt pretensioner units.
- Triggering unit after the system is triggered for the third time.
Because it is difficult to visually determine if one or more seat-belt pretensioners has been triggered, check the following points:
- Use PIWIS Tester II 9818 to read out the fault memory.
- Check plug connection on the seat-belt pretensioner for damage.
- Pull out the belt strap as far as possible and check for wear.
- Perform a function test on the automatic belt device.
