Restraints and Safety Systems: Testing and Inspection

General Information

The airbag system is constantly monitored by a diagnosis unit in the triggering unit. Any fault is signalled by a warning light. The warning light for the airbag system lights up in the event of a fault. The airbag warning light lights for approx. 3 seconds after the ignition is switched on and goes out if no fault has been entered in the fault memory. If it lights up again, this indicates a fault in the system. The fault can be read out with the Porsche System Tester 2.

NOTE:
- A period of 10 seconds is required to enable the triggering unit to identify all faults in the system.
- In order to guarantee that every possible fault source is checked during the vehicle test, the ignition must be switched on for at least 10 seconds.
- The fault memory must be cleared following a fault in the airbag system and after it has been remedied.
- The replacement of a component must be noted in the Guarantee and Maintenance booklet.
- To do this, attach the documentation number in a free panel intended for that purpose.
- The documentation number is attached to the replacement part as a tear-off sticker.
- Exchanged airbag units or airbag modules must be taken into possession by the Porsche Centre or by a dealer authorized by Porsche and must not be handed over to the customer (customer has no right to possess them). They must be destroyed, disposed of or returned to the manufacturer in accordance with the explosives ordinance and the hazardous materials ordinance.
- When the steering wheel is exchanged, e.g. to install a steering wheel from the Equipment product range, the airbag unit of the replaced steering wheel must be removed and destroyed, disposed of or returned to the manufacturer before the steering wheel is handed over to the customer.

Component exchange after airbag triggering
The following components must be removed and replaced after the airbag system is triggered:

After triggering of the airbag unit on the driver's side:
- Contact unit
- Airbag unit, driver's side

After triggering of the airbag unit on the passenger's side:
- Airbag unit, passenger's side
- Triggering unit after the third time the airbag is triggered
- Instrument panel

After triggering of the side airbag unit
- Side airbag unit
- Sensor for the side airbag unit after the third time the side airbag is triggered
- Deformed or damaged components on the seat

After triggering the seat-belt tensioner
After triggering of the belt tensioner, driver's, passenger's, and/or rear unit.

After triggering one or more airbag units (driver's, passenger's, head and/or side airbag).
- All belt tensioner units

NOTE:
Because it is difficult to visually determine if one or more belt tensioners has been triggered, check the following points.
- Read out the airbag fault memory with the Porsche System Tester.
- 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.
