Interior Motion Sensor (IMS) (4/237) [2018-2022]: Description
The Interior Motion Sensor (IMS) detects movements in the passenger compartment.
The Interior Motion Sensor (IMS) sends out ultrasound into the passenger compartment. The soundwaves are reflected back to the sensor by the interior of the vehicle. If the Interior Motion Sensor (IMS) detects changes in the reflections, an alarm is triggered. The Interior Motion Sensor (IMS) is sensitive to air turbulence and therefore all windows and the roof hatch must be closed for optimal sensor performance.
