Forward Facing Radar
The forward facing radar is a sensor that is connected to the Forward Sensing Module (FSM). Information transfer between the radar and the Forward Sensing Module (FSM) occurs via local CAN communication. The radar is positioned in the front section of the vehicle (behind the grille).
The forward facing radar is only found in vehicles equipped with adaptive cruise control, collision warning, automatic braking/brake support and distance control.
The forward-sensing radar is used to (identify and) sense targets (vehicles in front) that move in the same direction in front of one's own vehicle. When a target is detected, the radar senses the target's speed and distance in relation to the own vehicle.
When replacing the forward facing radar, the new unit must be calibrated using the diagnostic tool.
This must also be done when replacing the control module during software downloading.
