A seat occupation mat that changes its electrical resistance as the weight load increases is located under the seat cushion. The seat occupancy electronics evaluate these changes. The signal ”seat occupied” or ”seat not occupied” is forwarded by the seat occupation electronics to the airbag control unit. As of a weight of around 12 kilograms, the seat is recognised as occupied.
Note:
All work on the airbag must only be conducted with the battery disconnected!Connect and disconnect airbag control unit, sensors and gas generators only with the battery disconnected!The airbag control unit contains vehicle-specific data and must therefore be encoded before placing into operation!Removal and installation in other vehicles is prohibited!
