Driver Assistance Systems Front Camera R242, Calibrating, Static

Special tools and workshop equipment required

Setting Device - Basic Set: VAS6430/1A
Calibration Board For Lane Guard System: VAS6430/4

Preparing

Requirement

Refer to Necessity of Calibration .
There may be no DTC memory entry present because they prevent the calibration.

-- Check the camera's field of view.

If the camera can no longer recognize the lane markings due to poor visibility, this could be caused by:

Dirt or ice in the camera's field of vision.
The camera's field of vision is fogged over.

Requirement

If there is heavy contamination on the inside of the windshield in the camera's field of vision, the area must be cleaned by hand. For this, remove the camera and the lens, then clean the windshield with cleaning solution. Refer to Parts Information.

-- Pay attention to the test requirements for the axle alignment. Refer to TEST REQUIREMENTS .

-- Note the measurement preparations for an axle alignment with assistance systems. Refer to MEASUREMENT PREPARATIONS .

-- Check the camera, bracket, and retainers for damage, external influences, and secure fit.

-- Check if the floor space between the vehicle and the Setting Device Basic Set: VAS6430 is sufficient before driving the vehicle onto the wheel alignment platform.

Requirement

The distance in between the setting device and the center of the wheel hub of the front wheels must be 1500 mm ± 25 mm.

Tip

If the available floor space is not sufficient, drive the vehicle onto the wheel alignment platform backward and then use the corresponding floor space.

-- Drive the vehicle straight onto the wheel alignment platform.

-- Move the wheels into the straight position.

-- Install the quick-action clamp to the front wheels.

-- Install reflectors on the quick-action clamps.

-- Connect the Vehicle Diagnostic Tester, select the program, and follow the instructions.

-- Measure and record the height -a- at all four wheels.

-- Position the setting device in a distance of -a- from the center of the wheel hub of the front wheels to the beam on the setting device.

Requirement

Dimension -a- = 1500 mm ± 25 mm

-- Measure the distance -a- with the distance measuring device -1- on both sides of the vehicle and align the setting device.

Requirement

Distance -a- must be the same on both sides of the vehicle.

-- Attach the sensor -1- to the setting device and tighten.
