Parking Distance Warning Sensor
Parking Distance Warning Sensor detects obstacles in front and rear of the vehicle and sends first phase, second phase, third phase warning signals that differ by distance of obstacles to BCM* via LIN communication.
BCM* monitors signals from the sensor and determines warning phase and activates buzzer or sends data to cluster to display to warn driver. Warning methods are different by vehicle options.
