Front passenger seat occupied recognition sensor, component description - GF91.60-P-4110SX
MODEL 216.3, 221.0 /1 as of 1.6.07 except CODE (494) USA version except CODE (U18) Automatic child seat recognition (ACSR) up to Model Year 8
Location
The front passenger seat occupied recognition sensor is integrated in the seat cushion of the front passenger seat.
Task
The seat occupied recognition detects whether the front passenger seat is occupied or not, and notifies the restraint system control unit.
Function
If the front passenger seat is occupied by a person, the pressure load of the seat area increases. This pressure load is recognized by the force sensing resistors integrated in the seat cushions.
The signal is evaluated by the restraint systems control unit (N2/7) and relayed to the instrument cluster (A1) in order to implement the seat belt reminder warning function.
