Airbag Sensors

Function
The sensor system of the ACSM differs due to different crash test requirements in ECE and US vehicles. The sensors detect and verify frontal, side-on and rear-end crash. The sensor signals go directly to the crash safety module and are evaluated there.

The crash safety module calculates the crash direction and the crash severity from the values sent by the sensors. For detection of a crash, the thresholds of two independent sensors must be exceeded.

NOTE: All work on the airbag must only be conducted with the battery disconnected.Connect and disconnect airbag control module, sensors and gas generators only with the battery disconnected.The airbag control module contains vehicle-specific data and must therefore be encoded before placing into operation.Removal and installation in other vehicles is prohibited
