1. Understanding Mercedes Seat Occupancy Sensor Parameters

The Mercedes-Benz seat occupancy sensor, also known as a seat occupancy detection (SOD) system, is a critical component of the vehicle’s Supplemental Restraint System (SRS). This system determines whether a seat is occupied, and if so, the weight of the occupant. This information is used to adjust the deployment of airbags in the event of a collision, optimizing safety for the occupant. As a professional technician, understanding the live data values of these sensors is essential for accurate diagnostics and repair.

2. Why Seat Occupancy Sensors Matter for Safety

Seat occupancy sensors play a vital role in modern vehicle safety systems. According to research from the National Highway Traffic Safety Administration (NHTSA), advanced airbag systems that incorporate seat occupancy sensors can significantly reduce the risk of airbag-induced injuries, especially for children and small adults.
