WSS (Weight Sensing System) control unit, component description - GF91.60-P-4046SCU
MODEL 216.3 with CODE (494) USA version up to Model Year 8
Location
The WSS control unit is located at the seat frame of the front passenger seat.
Task
- Power supply and evaluation of the seat occupied recognition pressure sensor (B48/4)
- Power supply and evaluation of the belt tension sensor (B48/3)
- Calculation of classification of weight on front passenger seat
- Provision of weight classification via the interior CAN
- Self-test of WSS control unit, seat occupied recognition pressure sensor and belt tension sensor
- Storage of detected faults
The WSS control unit evaluates the data from the seat occupied recognition pressure sensor and the belt tension sensor. The measurements are used to assign a weight classification to the weight on the seat, which is then sent to the restraint systems control unit (N2/7) via the interior CAN and the chassis CAN for precise control of the front passenger airbag unit.
Discrete inputs
- Circuit 30
- Circuit 31
- Seat occupied recognition pressure sensor data
- Data of the belt tension sensor
Discrete outputs
- Seat occupied recognition pressure sensor power supply
- Belt tension sensor power supply
CAN signals
The WSS control unit is an interior CAN subscriber.
