deviating modifications specific for these models are described in this model information brochure.

"he Supplementary Restraint System (SRS) consists of an airbag control unit, two crash sensors, an airbag unit in the steering wheel, contact unit and front passenger's airbag unit.

Airbag Control Unit

(In RHD cars the control unit for cruise control is still located underneath the center console.)

Airbag system is diagnosable. Fault memory of the airbag control unit can be read via the 19 pin diagnosis plug of the car with help of a 9268 Flashing Code Tester or Porsche 9288 System Tester.
