Understanding your Obstacle Detection System’s functions Your system sends and receives Ultrasonic Signals that are projected from sensors mounted in the Sensing Unit. As the signals “echo” off of objects in the detection field, and return to the sensors, the systems’s microprocessor exports them to its onboard, output signal transmitter. These signals are transmitted through Radio Frequency Waves to the Chime Module located in the vehicle. The detection signals are then translated into audible

Situations Where Momentary, or No Detection is Experienced Your system utilizes highly advanced Ultrasonic technology to locate objects in your vehicle’s path. Under some circumstances however, an object may not be detected. Always use extreme caution when reversing, looking behind your vehicle and maintaining speeds of less than 3 miles-per-hour. A small object, which is under your bumper or too close to the vehicle, may not be detected due to the dispersion of the sensor’s signal. When reversi

Reversing at an angle towards a partial wall or other large flat surface may refract ultrasonic signals, causing an object not to be detected. If reversing towards a 90 degree angle, such as a corner of a wall or pillar, sensor detection pattern will refract as shown until vehicle is close enough to receive signal back from corners. In such situations, vehicle could reach very close distances before detecting. Due to natural projection angle of the sensors, a natural “no coverage” area is common
