GF91.60-P-4069MCU Weight Sensing System (WSS) Control Unit, Component Description







N110 Weight Sensing System (WSS) control unit

Location
The WSS control unit is located on the bottom of the front passenger seat.

Task
The WSS control unit determines the weight on the front passenger seat. This is determined via a pressure measurement in a gel mat filled with silicone. The pressure measurement is performed by the pressure sensor of the seat occupied recognition (B48/4).
The tractive force at the belt is transmitted via the belt tension sensor (B48/3) to the WSS control unit.
The WSS control unit uses the pressure and belt tension to calculate the corresponding weight class and forwards this to the instrument cluster (A1) via the Controller Area Network bus class B (interior) (CAN-B).
