Impact detection

The Crash Safety Module (ACSM) detects all impacts throughout a 360° range.

Within the Crash Safety Module the direction and severity of the impact are determined based on inputs from the following external sensors:

• Front airbag sensor on left and front airbag sensor on right (note national version)
• Airbag sensor for left front door and airbag sensor for right front door (note national-market version)
• Left B-pillar airbag sensor and right B-pillar airbag sensor
• Longitudinal acceleration sensor and lateral acceleration sensor for impact recognition in the ICM control unit
• Vertical acceleration sensor in the ICM control unit (note vehicle equipment level and national-market version)
• Yaw rate sensor in the ICM control unit (note vehicle equipment and national-market version)

The Crash Safety Module processes all acceleration data. This determines the direction of a collision and the severity of the accident.
