Driver Assistance Systems Front Camera, Calibrating
Special tools and workshop equipment required
- Wheel Alignment Computer approved by VW/Audi
- Vehicle Diagnostic Tester
- Wheel Alignment Computer - Camera: VAS701001/1
- Setting Device - Basic Set: VAS6430/1A
- Adapter VAS6430/9 : VAS6430/9 , only for surface mounted hoist with a dimension greater than 300 mm.
There are two options that can be selected for the calibration:
The "complete alignment"
This procedure should be selected for the following activities if a wheel alignment and calibration/adjustment should be performed.
- The rear axle toe was adjusted.
- The vehicle suspension was changed, for example changing from standard to sport suspension.
The "quick guide"
This procedure should be selected for the following activities if only the calibration/adjustment will be performed.
- The test plan in the Vehicle Diagnostic Tester requires a recalibration.
- The Driver Assistance Systems Front Camera -R242- was removed and installed or replaced.
- The bracket for the Driver Assistance Systems Front Camera -R242- was removed and installed or replaced.
- The lens was replaced (window defogger faulty).
- The inner side of the opening on the glass was cleaned.
- The wire for the Driver Assistance Systems Front Camera - R242- was replaced.
- The connector for the Driver Assistance Systems Front Camera - R242- was touched.
- The windshield was removed and installed or replaced.
- The standard vehicle height was reprogrammed.
TIP:
- Both procedures are programmed in the wheel alignment computer. The procedure is automatically performed. The corresponding program for the procedure to be performed must be selected.
- If only the calibration/adjustment of the Driver Assistance Systems Front Camera -R242- should be performed, select the "quick start" mode on the wheel alignment computer.
- The procedure in the "quick start" mode is described in the information that follows.
Procedure
As an example, the procedure is described for the : VAS701001 .
- Note the test requirements. Refer to TEST REQUIREMENTS .
- Follow the measurement preparations for calibrating/adjusting the driver assistance systems. Refer to MEASUREMENT PREPARATIONS .
-- Check if the : VAS6430 is in the center position and is locked.
-- Check if the Driver Assistance Systems Front Camera -R242- fits correctly in the bracket and the viewing range for the camera is not blocked.
-- Vehicle with rear axle steering: drive the vehicle "straight" onto the alignment rack. Switch off the ignition when the vehicle has come to a stop.
-- 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.
-- Vehicle with air suspension: adjust to standard vehicle height and lock. Refer to Air Suspension .
-- Check the DTC memory for the Driver Assistance Systems Front Camera - R242-. Correct all displayed entries.
-- Move the wheels so that they are in a straight-ahead position.
-- Install quick-action clamps on the wheels.
-- Attach the reflectors to the quick-action clamps.
-- Carry out wheel run-out compensation.
-- Select the button for the driver assistance systems front camera calibration procedure in the wheel alignment computer.
- The Setting Device must not be moved on the calibration beam.
-- Check the calibration board to make sure it is centered and secured in place.
- Dimension -a- = Dimension -b-
-- Position the : VAS6430/1A at a distance of -a- 150 cm ± 2.5 cm from the center of the wheel hub on the front wheels to the beam on the : VAS6430/1A .
- Measuring tape
-- Place the : VAS701001/1 -1- for the ACC adjustment on the : VAS6430 on the right side and tighten.
- For the next step, the alignment rack must be at the lowest level position.
-- Determine height -A- between the contact surface on the : VAS6430 and the wheel contact surface as shown in the illustration and enter this value into the wheel alignment computer.
- Height of the calibration board: 1, 400 mm + height value -A-.
-- Loosen the bolt -arrow- and position the measurement plate -1- on the ground.
-- Adjust the calibration board to the specified height -2- according to the wheel alignment computer using the crank -1-.
TIP:
Once the specified height -2- is reached, the measurement plate must be slid upward slightly and secured with the clamping screw.
- If the height of the calibration board is corrected at another point in the procedure, make sure that the measurement plate touches the floor at that point.
-- Bring the bubble level -A- into a level position using the adjusting screw -1-.
TIP:
The purpose of adjusting the level -A- is to compensate for uneven ground below the vehicle.
-- Move the : VAS6430 to the side in direction of -B arrows- until the display in the wheel alignment computer is within the tolerance range.
-- Secure the : VAS6430 to prevent it from rolling by lightly tightening the screws -2 and 3-.
-- Turn the fine adjustment screw -1- until the display on the wheel alignment computer is within the tolerance range.
-- Bring the bubble level -A- into a level position using the adjusting screw -1-.
-- Level the bubble level -B- using the adjusting screws -2 and 3-.
- Because the height may change slightly after adjusting the levels, check the height of the calibration board again. Refer to DRIVER ASSISTANCE SYSTEMS FRONT CAMERA, CALIBRATING - .
-- 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 - Driver Assistance Systems Front Camera, Calibrating
-- Start the selected program and follow the instructions on the Vehicle Diagnostic Tester display.
The next step is to determine the height of the vehicle body.
-- Determine the height of the vehicle body -a- at all four wheels in the center of the wheel between the wheel contact surface and the lower edge of the fender or wheel housing.
