GF91.60-P-4020-02QM Driver-Side/Passenger-Side Frontal Acceleration Sensor, Task

GF91.60-P-4020-02QM Driver-side/Passenger-side Frontal Acceleration Sensor, Task
- as of 1.6.04
- with CODE (494a) USA version

The driver-side frontal acceleration sensor (B48/1) and the passenger-side frontal acceleration sensor (B48/2) determine the acceleration values in the area of the left and right front sections of the vehicle. They support the triggering behavior of the restraint systems control unit (N2/7) during a frontal crash. They help the system to better determine whether an accident is severe enough to require the airbags to be triggered or not.

The restraint systems control unit (N2/7) can also trigger the restraint systems even if it does not receive any signals from the driver-side frontal acceleration sensor (B48/1) and the passenger-side frontal acceleration sensor (B48/2). In case of failure of the driver-side frontal acceleration sensor (B48/1), the signal from the passenger-side frontal acceleration sensor (B48/2) continues to be evaluated. This also applies vice versa.
