Airbag sensor: 

  1. Always replace all airbag sensors in damaged/deformed areas of the vehicle.
  2. Otherwise (i.e. even if the vehicle was not crashed), replace the airbag sensors if they show signs of mechanical damage and/or if the airbag control unit detects that the airbag sensor is faulty (use > 9900 - PIWIS Tester 3  to read out the fault memory).
  3. Triggering unit after the system is triggered for the third time.

Seat-belt pretensioner: 

  1. All belt tensioner units.
  2. Triggering unit after the system is triggered for the third time.

Because it is difficult to visually determine if one or more belt tensioners has been triggered, check the following points: 

Read out the fault memory using > 9900 - PIWIS Tester 3  .

Check plug connection on the belt tensioner for damage.

Pull out the belt strap as far as possible and check for wear.

Perform a function test on the automatic belt device.
