Circuit/System Description

The side object sensor modules use radar to determine the presence of objects nearby. Side blind zone alert is active when the vehicle is out of park or the parking brake is off on manual transmission vehicles. If a vehicle is detected in the side blind zone, the warning symbols will illuminate on the appropriate side. There is a private communication network between the B218L Side Object Sensor Module - Left and the B218R Side Object Sensor Module - Right.
