Calibrating the Front camera for driver assistance systems -R242- Special tools and workshop equipment required

t  Vehicle diagnostic, testing and information system -VAS 505X -

t  Setting device -VAS 6430- t  Wheel alignment computer   Note t  The driver assistance system's front camera -R242- must be correctly located in the holder. t  The field of view of the camera must be clean and clear. t  Before driving the vehicle onto the wheel alignment platform, make sure there is sufficient space between the midpoint of the hub of the front wheels and the setting device -VAS 6430-. t  The distance between the setting device -VAS 6430- and the centre point of the hub of the front wheels must be 1,500 mm ± 25 mm. t  If the available space is not adequate, move the vehicle backwards on the alignment platform as required. t  Before calibrating, read out event memory and rectify faults as necessary. –  Note testing preconditions for wheel alignment → Chapter. –  Drive car onto wheel alignment platform. –  Connect battery charger → Electrical system; general information; Rep. gr.27. –  Connecting the Vehicle Diagnosis, Testing and Information System -VAS 505X - to the vehicle. (Route diagnostic cable through open window.)   Note During the calibration, make sure that all doors are closed on the vehicle and that the exterior lights are switched off. –  Bring wheels into straight-ahead position. –  Select calibration run for driver assistance system's -R242- front camera. –  Attach quick-release clamps to all four wheels. –  Mount measuring transducers on wheels. –  Carry out wheel rim run out compensation for rear wheels. –  Bounce springs.

–  Measure and note the height -a- on all four wheels.   Note t  Setting device -VAS 6430- is not allowed to be moved on alignment beam. t  For the next step the wheel alignment platform must be set at the lowest available position. –  Align setting device -VAS 6430- at a right angle to lengthways axis of car.

–  Turn setting device -VAS 6430- upwards so that alignment beam is parallel to middle of measurement transducers on front wheels, in order to perform a correct measurement with distance measuring unit -1-. 1 -  Distance measuring unit with tape measure and socket pin –  Move the setting device -VAS 6430- to a distance -a- of 1,500 mm ± 25 mm, measured from the centre point of the wheel hub of the front wheels up to the bar of the setting device -VAS 6430-.   Caution t  Distance -a- of 1,500 mm ± 25 mm must be measured on both sides of vehicle and setting device -VAS 6430- must then be aligned. t  Distance -a- must be same on both sides of car. t  To guarantee correct calibration, setting device -VAS 6430- must be at right angle to lengthways axis of car.

–  Mount measurement transducer -1- of front wheels onto setting device -VAS 6430-.

–  Measure height value -a- between standing surface of setting device -VAS 6430- and wheel support surface on wheel alignment platform and enter value in wheel alignment computer.

–  Unscrew clamping bolt -arrow-, place measuring bar -1- on floor.

–  Use crank -1- to set calibration panel -VAS 6430/4- to nominal height -2- indicated by wheel alignment computer and make a note.

When nominal height has been reached, measuring bar -1- must be moved upwards slightly and secured with clamping screw -arrow-.

–  Set spirit level -A- to horizontal position with adjuster screw -1-.

–  Move setting device -VAS 6430- sideways -arrows B- until display on wheel alignment computer is within tolerance.

–  Screw down adjuster screws -2- and -3- slightly to secure setting device -VAS 6430- against rolling away.

–  Turn fine adjuster screw -1- until display on wheel alignment computer is within tolerance.

–  Set spirit level -A- to horizontal position with adjuster screw -1-.

–  Use adjuster screws -2- and -3- to level spirit level -B-.

–  Unscrew clamping bolt -arrow-, place measuring bar -1- on floor.

–  Check nominal height -2- again and correct if necessary.

When nominal height has been reached, measuring bar -1- must be moved upwards slightly and secured with clamping screw -arrow-. The following work sequences are carried out using the vehicle diagnostic, testing and information system -VAS 5051B-. –  switch ignition on. –  Select the „Guided fault finding “ → Vehicle diagnostic tester function in the vehicle diagnostic, testing and information system -VAS 505X -. Body Electrical system 01_Self-diagnosis capable systems A5_Front camera for driver assistance systems -R242- A5_Camera for driver assistance systems, Functions A5 - Calibrating the control unit (Rep. Gr. 44) Follow instructions on screen to perform calibration.   Note The next step in Guided fault finding is to measure the body height.

–  Enter the noted standing height.
