Porshe 911 (997). Manual - part 1109

Note

Behaviour in cases of malfunction or danger

Protect from flames and heat.
In case of fire, inform the fire brigade on arrival about the units present.
Do not install mechanically damaged units or units that have fallen, even from a low height.
Always replace units that are mechanically damaged (bulges, cracks).
Because of the irritating combustion residues, only handle triggered airbags with protective gloves and
goggles.
In the case of contact with combustion residues, wash the affected skin with soap and water.
In the case of eye contact, wash the eyes out with water.

General information

Note

Airbags - general
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
authorised 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 Tequipment 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!

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
PIWIS Tester 9718

.

Component exchange after airbag/belt tensioner triggering

The following components must be removed and replaced after the airbag system is triggered:
Airbag unit, driver's side:

1. Contact

unit.

2. Airbag unit, driver's side.

3. Triggering unit after the third time the airbag is triggered.

Diagnostic system: reading out fault memory and activating systems

Airbag unit, passenger's side:

1. Airbag unit, passenger's side.

2. Triggering unit after the third time the airbag is triggered.

3. Instrument

panel.

4. Check instrument panel bracket for deformation and replace if necessary.

Side-airbag unit, seat:

1. Side-airbag unit, seat.

6. Seat covering, deformed seat components.

7. Sensor for the side-airbag unit after the third time the side-airbag is

triggered

Head airbag unit, door:

1. Head airbag unit.

9. Check door unit carrier for deformation and replace if

necessary.

10. Sensor for the side-airbag unit after the third time the side-airbag is triggered

Belt tensioner:

1. All belt tensioner units.

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

–  Using the PIWIS Tester 9718, read out the fault memory.

–  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.

WARNUNG

Gefahr des Verlusts der Text-Bild-Zuordnung beim Ausdruck.

Aus technischen Gründen kann derzeit nicht ausgeschlossen werden, dass trotz
einwandfreier Darstellung auf dem Bildschirm beim Ausdruck der
Zusammenhang von Text und zugehörigem Bild verloren geht.

• 

Wird der Fehler nicht bemerkt, besteht die Gefahr, daß Arbeiten nicht korrekt
durchgeführt werden und es dadurch zu Personen- und Sachschäden kommt.

• 

→ Vergleichen Sie deshalb nach dem Druckvorgang unbedingt die Ausdrucke mit der
Bildschirmdarstellung. Korrigieren Sie die Ausdrucke im Fehlerfall so, daß der Inhalt der
Bildschirmdarstellung zutreffend wiedergegeben wird.

WARNING

Danger of losing text-figure correspondence when printing out.

For technical reasons, it can currently not be ruled out that the correspondence
between text and associated figure can be lost when it is printed out, even though
the display on the screen is correct.

• 

If the fault is not noticed, there is the danger that work will not be performed
correctly which can cause injury and damage.

• 

→ Therefore, always compare printouts with the screen display after printing them out. Correct
the printouts if they are faulty so that the content of the screen display matches that on the
printouts.

AVERTISSEMENT

Risque de perte de la correspondance texte-illustration lors de l'impression papier.

Pour des raisons techniques, il ne peut pas être exclu à l'heure actuelle que, même
en cas d'affichage correct à l'écran, la correspondance entre le texte et l'illustration
puisse être erronée sur l'impression papier.

• 

Si l'erreur passe inaperçue, on court le risque d'exécuter certaines opérations de
manière incorrecte pouvant conduire à des dommages corporels et matériels.

• 

→ Comparez impérativement pour cette raison les impressions papier avec l'affichage à l'écran.
Corrigez-les en cas d'erreur de manière à reproduire correctement l'affichage à l'écran.

ATTENZIONE

Pericolo di perdita dell'abbinamento testo-immagine nella stampa.

Per motivi tecnici non è escluso che, nonostante la rappresentazione sullo schermo
risulti perfetta, durante la stampa venga persa la corrispondenza fra testo e
relativa immagine.

• 

Se tale difetto non viene rilevato vi è il pericolo che i lavori non siano eseguiti
correttamente; ciò può avere come conseguenza lesioni e danneggiamenti.

• 

→ Per questo motivo, dopo la stampa è assolutamente necessario confrontare le stampe con la
rappresentazione sullo schermo. In caso di errore si prega di correggere le stampe, così da
garantire la riproduzione esatta della rappresentazione sullo schermo.

ADVERTENCIA

Al imprimir se corre el riesgo de perder la correcta asignación de las figuras al texto.

Por motivos técnicos, por el momento no se puede descartar que, aun siendo
correcta la imagen que aparezca en la pantalla, al imprimir se pierda la
correlación entre el texto y la figura correspondiente.

• 

Si este error pasara desapercibido, existe el riesgo de que los trabajos no se
ejecuten de forma correcta y, por tanto, se produzcan daños personales y
