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.

Indicator, visual collision warning




Indicator, visual collision warning consists of 12 LEDs in three groups. The LEDs are directly connected to the Forward Sensing Module (FSM).
The indicator is used to visually warn the driver that a collision is imminent, in order to reduce the risk of, or prevent, collision. The indicator is also used to visually inform the driver when the time interval to the vehicle in front is shorter than the set interval.
The visual collision warning indicator is located at the upper edge of the dashboard on the driver's side.
The Forward Sensing Module (FSM) controls the light intensity at the visual collision warning indicator via pulse width modulation. The three groups of LEDs are separately connected to the Forward Sensing Module (FSM), this means that the Forward Sensing Module (FSM) can control each group of LEDs individually.
The indicator has an internal temperature sensor. The task of the temperature sensor is to protects the electronics. At temperatures above 100 °C / 212 °F the indicator does not light the LEDs when the Forward Sensing Module (FSM) requests it. When this has occurred, the Forward Sensing Module (FSM) prevents the indicator from being lit for a further 10 minutes.

Forward facing camera




The front facing camera is a sensor that is connected to the Forward Sensing Module (FSM). Information is sent from the camera to the Forward Sensing Module (FSM) in the form of an analogue video signal.
The camera is located at the upper edge on the inside of the windscreen, by the rear view mirror.
The forward facing camera is used to provide the control module with information about stationary and moving objects, as well as to identify and measure road lines.
To prevent condensation forming on the windscreen in front of the camera there is a heating element that is controlled via the control module.
When replacing the forward facing camera or the Forward Sensing Module (FSM), the new module must be calibrated using the diagnostic tool. This must also be done when replacing the control module during software downloading.
