WSS (Weight Sensing System) control unit, component description - GF91.60-P-4046GZ
MODEL 164 with CODE (494) USA version
The WSS (Weight Sensing System) control unit (N2/13) is located on the front passenger seat frame. It measures the applied weight of a person or a mounted child seat on the front passenger seat via the sensors
- B48/11 Left front WSS (Weight Sensing System) sensor,
- B48/12 Right front WSS (Weight Sensing System) sensor,
- B48/13 Left rear WSS (Weight Sensing System) sensor,
- B48/14 Right rear WSS (Weight Sensing System) sensor,
which are mounted on the seat frame.
The measured values are used to determine a weight class for the applied weight and made available to the restraint systems control unit (N2/7) for exact control of the airbag stages.
The WSS control unit tasks are:
- evaluation and voltage supply of the four WSS sensors
- calculation of the weight class of an applied weight of a person or a mounted child seat on the front passenger seat
- provision of weight class data via the Controller Area Network bus Class B (interior) (CAN-B)
- self-test of WSS control unit and WSS sensors. In the event of a defect, an entry is made to the fault memory
