◆ Airbag units
◆ Belt tensioners
◆ Belt force limiters
◆ Battery disconnecting elements
General
◆ Testing, installation and maintenance tasks must only be
carried out by trained personnel.
◆ There are no replacement intervals for airbag units.
◆ Do not check using circuit tester, voltmeter, or ohmmeter un-
der any circumstances.
◆ Pyrotechnic components must only be checked when instal-
led and using ⇒ vehicle diagnostic testers that have been
approved by the manufacturer.
◆ When working on pyrotechnic components and the airbag
control unit -J234-, the battery earth wire must be disconnec-
ted when the IGNITION is SWITCHED ON. The battery neg-
