UIS Sensor (coupe only)

The UIS Sensor (Ultrasonic) is mounted at the rear of the vehicle on the headliner. Every time the DWA is armed the UIS sensor adapts to whatever objects are stationary in the interior.

The sensor emits ultra sonic waves in a programmed timed cycle and receives echoes of the returning waves. The UIS amplifies the returned sound wave signals and compares them with the transmitted waves. Similar echoes received indicate no movement is detected. Inconsistent or altered returned signals indicate motion in the interior. When motion is detected the UIS changes to a constant rather than timed program and compares returning echoes. If inconsistencies are still present the BC1 is notified of the motion.
