Driver Assistance Systems Front Camera, Adjusting
Special tools and workshop equipment required
- Setting device VAS 6430
- Wheel alignment computer
- =>
The driver assistance systems front camera -R242- must fit correctly in the retainer.
The camera viewing range must be clean and unobstructed.
Before driving the vehicle onto the vehicle alignment platform, make sure there is sufficient space between the center of the wheel hub on the front wheels and the adjustment device VAS 6430
The distance between the adjustment device VAS 6430 and the center of the wheel hub on the front wheels must be 1, 500 mm +/- 25 mm.
If there not enough space, back the vehicle onto the vehicle alignment platform so that there will be enough space.
The calibration board must be positioned in the center of the setting device.
Check the DTC memory before calibrating. Erase any entries if necessary.
-- Follow the prerequisites for alignment WHEEL ALIGNMENT PREREQUISITES .
-- Drive the vehicle onto the vehicle alignment platform.
-- Connect the battery charger Battery, Starter, Generator, Cruise Control .
-- Connect => to the vehicle. (Guide the diagnostic cable through the open window.)
During the calibration procedure, make sure all the vehicle doors remain closed and the vehicle exterior lighting is switched off.
-- Position the front wheels so they are straight.
-- Select calibrating the driver assistance systems front camera in the wheel alignment computer.
-- Install the quick clamps on all four wheels.
-- Mount the measuring sensors on the wheels.
-- Perform a rim run-out compensation on the rear wheels.
-- Bounce the vehicle.
-- Measure and record the ride height at all four wheels.
The adjustment device VAS 6430 must not be moved on the calibration beam.
The alignment stand must be in the lowest level position for the next step.
-- Rotate the adjustment device VAS 6430 upward just enough so that the calibration beam is parallel to the center of the measuring sensors on the front wheels, so that it is possible to correctly measure the distance measuring unit -1-.
- Distance measuring unit with spring tape measure and mounting pin
-- Position the setting device VAS 6430 at a distance -a- of 1500 mm +/- 25 mm from the center of the wheel hub on the front wheels to the beam on the setting device VAS 6430.
- Distance -a- 1, 500 mm +/- 25 mm must be measured on both side of the vehicle and then the adjustment device VAS 6430 must be aligned.
- Distance -a- must be the same on both sides of the vehicle.
-- Mount the front wheel measuring sensors -1- to the adjustment device VAS 6430.
-- Determine the height value -a- between the adjustment device VAS 6430 contact patch and the wheel contact surface on the vehicle alignment platform and enter it in the alignment computer.
-- Loosen the clamping bolt -arrow- and place the measuring bar -1- on the floor.
-- Turn the crank -1- to adjust the calibration board VAS 6430/4 to the height specification -2- and then make a note of it.
If the specified height was reached, then the measuring bar -1- must be pushed slightly forward and secured with the locking bolt -arrow-.
-- Level the bubble level -A- using the adjusting screw -1-.
-- Slide the adjustment device VAS 6430 to the side -arrows B-, until the display in the wheel alignment computer is in the tolerance range.
-- By gently turning the adjustment screws -2- and -3- secure the adjustment device VAS 6430 from rolling away.
-- Turn the precision adjustment screw -1- until the display on the alignment computer is located within the tolerance range.
-- Level the bubble level -A- using the adjusting screw -1-.
-- Level the bubble level -B- using the adjusting screws -2- and -3-.
-- Loosen the clamping bolt -arrow- and place the measuring bar -1- on the floor.
-- Check specified height -2- one more time and adjust if necessary.
If the specified height was reached, then the measuring bar -1- must be pushed slightly forward and secured with the locking bolt -arrow-.
Perform any subsequent work using => .
-- Switch on ignition.
-- Select "Guided Fault Finding" on => .
