Parking Distance Warning (PDW) Description And Operation

PDW consists of 8 sensors (front : 4 units, rear : 4 units) that are used to detect obstacles and transmit the result in three separate warning levels, the first, second and third to BCM via LIN communication.
BCM decides the alarm level by the transmitted communication message from the slave sensors, then operates the buzzer or transmits the data for display.
