–  Switch on ignition.
–  With ignition switched on, disconnect battery earth wire → Electrical system; Rep. gr.27.
   
–  Remove door trim → Chapter.
  WARNING
Before handling pyrotechnic components (e.g. unplugging the electrical connector) the mechanic must discharge static electricity by briefly touching the door striker plate, or similar.
–  Release catch -1--arrow- and unplug electrical connector -2-.
–  Remove bolts -3- and detach crash sensor for side airbag -4-.
Installing
  WARNING
t  Observe safety regulations for pyrotechnic components → Chapter.
t  Observe precautionary measures for handling crash sensors (pressure sensors) for side airbag (front) → Chapter.
t  Before handling pyrotechnic components (e.g. plugging in the electrical connector) the mechanic must discharge static electricity by briefly touching the door striker plate, or similar.
Installation is carried out in the reverse order; note the following:
  Note
t  Make sure electrical connectors are fitted correctly (as far as stop) and engage audibly.
t  Make sure that the door is properly sealed when it is installed; otherwise the crash sensor (pressure sensor) may not function correctly.
t  Make sure that all components (e.g. cover panel, loudspeaker, door trim) are fitted correctly.
t  The retaining clips for the door trim provide a seal for the system. If necessary, renew retaining clips.
t  Make sure that wiring is not trapped.
  WARNING
The battery must be connected with the ignition switched on. If pyrotechnic components (e.g. airbag or belt tensioner) are inexpertly repaired, this may result in unwanted triggering after connecting the battery. There must not be anyone in the vehicle while you are connecting the battery.
–  With ignition switched on, connect battery earth wire → Electrical system; Rep. gr.27.
  Note
If the airbag warning lamp -K75- indicates a fault following installation, you must interrogate, erase and then re-interrogate the event memory → Vehicle diagnostic tester.
