    1. 1.1. PIWIS Tester II 9818  must be connected and switched on.
    2. 1.2. Switch on ignition.
    3. 1.3. Establish communication with the airbag control module.
    4. 1.4. Read out fault memory: No fault stored.
    5. 1.5. Select Drive link test menu.
    6. 1.6. Read out fault memory for all control units and erase if necessary.
    7. 1.7. Remove ignition key. Disconnect battery. Route or isolate the ground strap so that all contact with a ground carrier (e.g. body) is avoided. → 2706IN WORK INSTRUCTIONS AFTER DISCONNECTING THE BATTERY
    WARNING: Incorrect handling of airbag units
    • Triggering of airbag unit.
    • System faults can occur.

    → Switch off ignition and remove ignition key or remote control (hand-held transmitter).

    → A power supply (e.g. battery charger) must not be connected to the external power supply/jump-lead starting terminals.

    → Disconnect the battery and insulate the ground strap so that all contact with a ground carrier is avoided.

    → Wait 1 minute after disconnecting the battery.

    → Only pull off connector on the triggering unit after the waiting time has elapsed.

    → Make sure that no foreign objects are located in front of the airbag unit during installation.

    → Replace damaged parts during removal.

    → Always position airbag units so that the blow-out opening is facing upwards, e.g. crest on driver's airbag.

    → Do not position anything on the airbag units.

    → If removed for an extended period, the airbag units must be stored in a safe place.

    → Airbag units must not come into contact with grease, oil, detergents, liquids, or similar substances.

    → Do not expose airbag units to temperatures above 90°.

    → Do not remove the short-circuit spring on the plug-in contacts.

    → Ignition and preparations may only be carried out by skilled staff, supervised by a second responsible person.

    → Before disposal, the airbag unit must be rendered harmless by electrical ignition performed in accordance with all precautionary measures, thereby preventing it from being used incorrectly.

  2. Simulating the fault: 

    Information 

    • To check the operation of the airbag system, a plug connection is disconnected from an airbag unit. A fault code - Static fault - must then be stored in the Porsche System Tester. 
    1. 2.1. Simulate the fault using the side airbag, for example. Move seat all the way forward. Switch off ignition, disconnect the battery and wait for 1 minute.
    2. 2.2. Unlock and disconnect electric plug for the seat.
    3. 2.3. Connect the battery and switch on ignition.
    4. 2.4. Read out fault memory. Static fault present.

  3. Correcting the fault: 
    1. 3.1. Switch off ignition, disconnect the battery and wait for 1 minute.
    2. 3.2. Insert connector in plug socket until connector is felt to engage.
  4. Reading out and deleting faults: 

    Information 

    • Fault memory shows a sporadic fault. 
    1. 4.1. Connect the battery, switch ignition on and read out the fault memory with the Porsche System Tester.
    2. 4.2. Erase fault memory.

    Carry out work instruction after disconnecting the battery. → 2706IN WORK INSTRUCTIONS AFTER DISCONNECTING THE BATTERY
