Events

Event data can be read out in the menu item "Events" after airbag triggering. Up to max. three events can be stored. The airbag triggering unit must be replaced after the third event, since the airbag warning light lights up continuously and the events cannot be deleted.

Lock

An unlocked triggering unit can be locked under the menu item "Locking". When the airbag triggering unit is replaced, the new air- bag triggering unit must be locked.

NOTE:
- As long as the airbag triggering unit is not locked, the airbag warning light lights up continuously.
- A locked airbag triggering unit cannot be unlocked again.

If an airbag triggering unit is unlocked, the airbag warning light flashes. The airbag triggering unit must then be locked.

The airbag triggering unit is delivered from the Parts Service dealers in an unlocked state.

Procedure:
1. Connect the Porsche System Tester 2 No. 9588 and switch on the ignition
2. Select vehicle type, Boxster, and start the automatic control module search.
3. Select the menu item "Locking" and press the key [>>]
4. Porsche System Tester 2 indicates the vehicle type. Check the vehicle type and activate using the [F7] key
5. PST2 displays the vehicle identification number. Check vehicle identification number, accept with the key [>>], and code by pressing key [F7]
6. Porsche System Tester 2 shows "Start locking with [F8]" Press key [F8]. Subsequently, PST2 shows "Control module locking, please wait"

NOTE: The airbag triggering unit can only be locked when the instrument cluster has been coded (Veh. ident. No.). In the event that the instrument cluster is replaced simultaneously, code the instrument cluster first and then the airbag triggering unit.

If there is no fault, the following message is displayed after a short waiting period:

Airbag was locked

This ends locking.

The following messages can be displayed in a fault state:
Airbag was already locked
No Porsche control unit
Incorrect vehicle type
Incorrect database version
Incorrect equipment

In the event of a fault, the triggering unit cannot be locked.

In the case of the "wrong equipment" message, select the correct equipment.

Replace the triggering unit in the case of the other messages.
