Driver Assistance Systems Front Camera, Calibrating
There are two choices for calibrating:
The "Complete Alignment"
This procedure must be selected for the following activities if a wheel alignment and calibration should be performed.
- Rear axle toe/chamber was adjusted.
The "Quick Access"
This procedure should be selected for the following activities if only the calibration will be performed.
- The installation position of the Driver Assistance Systems Front Camera -R242- in the vehicle has changed.
- The connector for the Driver Assistance Systems Front Camera - R242- was touched.
TIP:
- Both procedures are programmed in the wheel alignment computer. The respective procedure is performed automatically. It is only necessary to select the appropriate program for the procedure that will be performed.
- If only the driver assistance systems front camera should be calibrated, select the "quick start" mode on the wheel alignment computer.
- The procedure in the "quick access" mode is described in the following.
Special tools and workshop equipment required
- Wheel Alignment Computer approved by VW/Audi
- Vehicle Diagnostic Tester
- Camera: VAS6331/1 or : VAS701001/1 , not illustrated
- Setting Device - Basic Set:VAS6430/1A
- Adapter VAS6430/9 :VAS6430/9 , only for surface mounted hoist with a dimension greater than 300 mm.
Procedure
The procedure is described on a John Bean Wheel Alignment Computer: VAS6331 .
The procedure may vary if using other wheel alignment computers. In this case, follow the instructions on the wheel alignment computer screen.
- Note the test requirements. Refer to the appropriate Service Information .
- Follow the measurement preparations for calibrating/adjusting the driver assistance systems. Refer to MEASUREMENT PREPARATIONS .
- Connect the battery charger for the battery support mode. Refer to BATTERY, CHARGING .
-- Check if the Setting Device Basic Set:VAS6430/1 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.
-- Adjust to standard vehicle height and lock at that height. Refer to Air Suspension .
-- Check the DTC memory for the Driver Assistance Systems Front Camera -R242-. Fix all displayed entries.
-- Drive the vehicle "straight" onto the alignment rack.
-- Move the wheels so that they are straight.
-- Install quick-action clamps on the wheels.
-- Attach the reflectors to the quick-action clamps.
-- Perform the wheel run-out compensation. Refer to WHEEL RUN-OUT COMPENSATION .
-- Select the button for the driver assistance systems front camera calibration procedure in the wheel alignment computer.
- The ACC Setting Device must not be moved on the calibration beam.
-- Make sure the calibration board is positioned in the center and is locked in place.
- Dimension -a- = dimension -b-.
-- Position the Setting Device Basic Set: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 Setting Device Basic Set :VAS6430/1A .
- Measuring tape
-- Position the Camera:VAS6331/1 or :VAS701001/1 -1- on the right of the Setting Device - Basic Set:VAS6430 and tighten it.
- For the next step, the alignment rack must be at the lowest level position.
-- Enter the height value -A- between the Setting Device Basic Set:VAS6430/1A contact patch and the wheel contact surface as shown in the illustration and enter it in the alignment computer.
- Height of the calibration board: 1, 400 mm + height value -A-.
-- Loosen the bolt -arrow- and place the measuring bar -1- on the floor.
-- Adjust the calibration board to the specified height -2- according to the wheel alignment computer using the crank -1-.
TIP:
If the specified height was reached -2-, then the measuring bar must be pushed slightly upward and secured with the clamping screw.
- If in later procedures the height of the calibration board must be corrected, make sure the measuring bar is touching the ground when this is being done.
-- Balance the bubble level -A- using the adjusting screw -1-.
TIP:
The bubble level adjustment -A- serves to balance the ground conditions.
-- Slide the Setting Device Basic Set:VAS6430/1 to the side in direction of -arrows B-, until the display in the wheel alignment computer is in the tolerance range.
-- Secure the Setting Device - Basic Set: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.
-- Balance the bubble level -A- using the adjusting screw -1-.
-- Level the bubble level -B- using the adjusting screws -2 and 3-.
- Because small height changes can result after adjusting the bubble levels, the height of the calibration board must be checked 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.
Next, determine the height of the 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.
-- Switch off the ignition after successful calibration.
-- Disconnect the Vehicle Diagnostic Tester from the diagnostic connection.
-- Disconnect the battery charger. Refer to BATTERY, CHARGING .
