Installation
• Follow all safety precautions when working on pyrotechnic components. Refer to => [ Restraint System Components, Safety Precautions and Testing Procedures ] Description and Operation.
• Before handling pyrotechnical components (for example, connecting electrical connector), the person handling them must "discharge static electricity". For example, by briefly touching the door striker pin.
Installation is performed in reverse order of removal, noting the following:
• Make sure the connectors are installed all the way in and are secure.
Connect the battery with the ignition switched on. Pyrotechnic components could deploy after connecting the battery if they were not repaired correctly. Individuals must not be inside the vehicle when connecting the battery.
When working on vehicles with the ignition turned on or where the engine has been started, there is a risk of unintentional engine start and of being poisoned by gas in closed areas. There is a risk of clothes and body parts being pulled or getting stuck.
Perform the following steps before turning on the ignition:
• Move the selector lever into P.
• Activate the parking brake
• Turn the ignition off.
• Open the hood.
• Connect the charger unit i.e., battery charger (VAS 5095A) to the battery jump start terminal for the 12V vehicle electrical system.
• Switch the ignition on.
- Connect the battery ground cable with the ignition turned on.
When installing a new service kit and after each repair on the front passenger seat where the seat and/or the backrest cover is disengaged, a basic setting procedure must be performed on the seat occupied recognition control module. Refer to => [ Passenger Occupant Detection System Deactivation Additional Safety Precautions ] Passenger Occupant Detection System Deactivation Additional Safety Precautions.
- Select "airbag" in "Guided Fault Finding" to complete. Refer to Vehicle diagnostic tester.
• -J706 Passive occupant detection system control module basic setting
• If the airbag indicator lamp (K75) indicates a fault after installation, check the DTC memory, erase it and check it again. Refer to Vehicle diagnostic tester.
