Seat Occupied Recognition, Not For Usa - Audi A6´05 323 Service

Passenger protection
Seat occupied recognition,
not for USA
Seat occupied sensor, front passenger side, G128 is
a plastic foil, which covers the rear part of the front
passenger seat. It consists of several individual
pressure sensors. This ensures that the relevant
part of the seat is sensed.
The seat occupied sensor, front passenger side,
reacts to pressure and changes its resistance,
depending on the load. If seat occupied sensor,
front passenger side, G128 is subjected to a load
greater than approx. 5 kg, the airbag control unit
detects "Seat occupied". As long as the front
passenger seat is unoccupied, the seat occupied
sensor has a high resistance. If the seat is occupied,
the resistance drops. If the resistance exceeds
480 ohms, the airbag control unit detects an
interruption and sets a fault in the fault memory.
The airbag control unit uses the information from
the seat occupied sensor and the belt lock switch
for the wearing belt detector.
