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 following components must be removed and replaced following an accident in which the airbag system was triggered:

The warning light for the airbag system lights up in the event of a fault.

Contact unit

Triggered airbag unit(s)

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.

The triggering unit must be replaced after the airbag is triggered for the third time.

If it lights up again, this indicates a fault in the system. The fault can be read out with the Porsche System Tester 2.

Warning: Danger of injury

> Observe safety instructions when working on the airbag system (see Serv. No. 69).


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.
