Calibration Of Radar And Camera: Information: Overview
When replacing for a new forward facing radar the radar must be calibrated. When replacing forward-sensing camera, the camera must be calibrated. When replacing Forward Sensing Module (FSM) or downloading software, both the camera and radar must be calibrated. Text message in the Driver information module (DIM) stating that the radar has not been calibrated. Calibration of forward-sensing radar and camera is performed by starting respective calibration procedure and then driving the vehicle. Then the radar measures stationary objects along the road, e. g., guard rails, signs, or similar, and adjusts electronically. The camera searches for road lines, road edges, pavements or similar shapes, which meets a point on the horizon.
If both radar and camera need to be calibrated, the text message goes out in the Driver information module (DIM) first when both calibrations have been completed.
Calibration can be performed at any time of day or night, but should be avoided at:
- Heavy rain.
- Snowfall.
Calibration of camera should be avoided when:
- Fog.
- Wet road at night.
- The dark areas without visible and narrow road lines.
When replacing with a new forward facing camera, replace the Forward Sensing Module (FSM) and on rare occasions, during software download, DTC FSM-C100154 is stored. When changing to a new forward sensing radar, when replacing Forward Sensing Module (FSM), or software download, the diagnostic trouble code FSM-U030055 is generated.
If both diagnostic trouble codes FSM-U030055 and FSM-C100154 are generated, calibrations for radar and camera should be performed at the same time. Start both the calibrations before driving.
Select the desired alternative:
- Read off diagnostic trouble codes (DTCs).
- Activate calibrations.
