Peripheral Camera, Calibrating
Special tools and workshop equipment required
- Calibration System: VAS721001
- Vehicle Diagnostic Tester
Calibration/adjustment must be performed if:
- One or more cameras were replaced.
- The Driver Assistance Systems Control Module -J1121- was replaced.
- The Driver Assistance Systems Control Module -J1121- was replaced.
- A software update was performed.
- A data set was written to the Driver Assistance Systems Control Module -J1121-.
- Repair work was performed on components in which a camera is installed or that influence the component location of the camera
- Wheel alignments were performed.
- There is a misalignment in the overlap range of the individual camera images.
- The standing height of one axle was changed by more than 5 mm.
- The standing height of the entire vehicle was changed by more than 10 mm.
Preparing for Calibration
- Left Calibration Device
- Front Peripheral Camera -R243-
- Right Calibration Device
- Right Peripheral Camera -R245-
- Rear Peripheral Camera -R246-
- Left Peripheral Camera -R244-
Preliminary Work
- Create a work surface that is large enough (no objects surrounding the calibration board to prevent any incorrect line detections).
- Prevent any strong lighting contrasts (no headlamps or direct lighting).
- Move the vehicle onto a solid, flat surface.
- Move the wheels so that they are in a straight-ahead position.
- For vehicles with rear axle steering, steer the rear axle to the zero position. Refer to Rear Axle Steering . This is the only way to ensure that the rear axle steering is in the straight-ahead position.
- Vehicles without air suspension: deflect the springs several times and let settle.
- Electromechanical parking brake applied.
- All vehicle doors and the rear lid must be closed.
- Fold out both exterior rearview mirrors.
- Clean the camera lenses with a damp cloth.
- Check the camera images on the Front Information Display Control Head -J685-. Replace the camera if the images are unclear because the camera has been damaged. Check the fastener for the camera if the image is low.
- The system is active and is displayed on the Front Information Display Control Head -J685-.
- Connect the battery charger for the battery support mode. Refer to BATTERY, CHARGING .
- Before starting the calibration/adjustment, check the DTC memory and correct all displayed entries.
Procedure
-- Roll out the Calibration System: VAS721001 at the left and right near the vehicle.
-- The arrows -1- on the Calibration System: VAS721001 point in the direction of travel.
-- Install the rear and front clamping strips on the Calibration System: VAS721001 .
-- Align the crosshairs -2- on the Calibration System: VAS721001 to the front axle of the vehicle (center of front wheel).
-- Align both calibration devices parallel. The vehicle must be located in the center between both calibration devices.
Pay attention to the following measurement requirements:
- Dimension -a- 2000 to 2500 mm ± 5 mm, front and rear the same
- The dimension -b- must be the same on both sides
- The dimension -c- must be the same on both sides
Calibration Procedure
The following should not occur during the calibration procedure:
- Vehicle doors must not be opened or closed.
- People must not sit in the vehicle.
- Vehicle must not be loaded (curb weight).
-- Connect the Vehicle Diagnostic Tester.
-- Switch the ignition on.
-- Select and start the Diagnostic operating mode.
-- Select the Test plan tab.
-- Select the Select individual test button and select the following tree structure consecutively:
- Diagnostic-capable systems
- 00A5 - Driver Assistance Systems Control Module
- 00A5 - Driver Assistance Systems Control Module, functions
- 00A5 - Peripheral camera, calibrating
-- Start the selected program and follow the instructions on the Vehicle Diagnostic Tester display.
-- Switch off the ignition after successful calibration/adjustment.
-- Disconnect the Vehicle Diagnostic Tester from the diagnostic connection.
-- Disconnect the battery charger. Refer to BATTERY, CHARGING .
