Video Processing Control Module Calibration: Notes
- The surround vision camera system image will be slightly distorted at all times, the camera(s) lens is a fish-eye lens meant to capture as much range as possible.
- A Video Processing Control Module that is not calibrated adequately will display an hour-glass icon on the surround vision camera system image screen, a DTC should be set, and one or more of the scan tool Camera Alignment Learn parameters will display Not Calibrated. Once calibration is attained, the hour-glass will automatically disappear and the scan tool Camera Alignment Learn parameters should display Stage 1, 2, or 3 showing no further calibration is necessary.
- The Video Processing Control Module can disable rear camera display guidelines if it is not calibrated adequately. Once calibration is attained, the guidelines should return.
The calibration procedure is needed to have the Video Processing Control Module learn new cameras and their positions. The calibration is performed automatically by the Video Processing Control Module.
If any one of the cameras is replaced on the Surround Vision Camera System, the camera image needs to be calibrated to the system. For this reason, the Video Processing Control Module performs a calibration during its power up and initialization during each ignition cycle in order to maximize the surround vision image quality.
A new Video Processing Control Module will have built-in default values for camera learn. However, the Video Processing Control Module will automatically calibrate in order adapt to the vehicle.
To allow the Video Processing Control Module to complete calibration, drive the vehicle. Driving the vehicle in the conditions listed below will reduce calibration time.
