Driver Assistance Systems Front Camera, Calibrating
Special tools and workshop equipment required
- Wheel Alignment Computer approved by VW/Audi
- Vehicle Diagnostic Tester
- Camera: VAS6331/1 for adaptive cruise control (ACC), not illustrated
- Setting Device - Basic Set: VAS6430/1 or Setting Device - Basic Set: VAS6430/1A
There are Two Choices for Calibrating:
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 Access"
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 readjustment.
- The Driver Assistance Systems Front Camera -R242- was removed and installed or replaced.
- The Driver Assistance Systems Front Camera -R242- bracket was removed and installed or replaced.
- The lens was replaced (window heating faulty).
- The inside of the black cut-out 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.
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 assistance systems front camera should be calibrated/adjusted, then the "quick access" mode must be selected on the wheel alignment computer.
- The procedure in the "quick access" mode is described in the following.
Procedure
The Procedure is Described using a John Bean aligner: VAS6331 .
The Procedure will Differ if Performed with Other Aligners. In this Case, Follow the Instructions on the Aligner Screen.
- Note the test requirements. Refer to AXLE ALIGNMENT TEST REQUIREMENTS .
- Follow the measurement preparations for calibrating/adjusting the driver assistance systems. Refer to MEASUREMENT PREPARATIONS .
-- Check if the : 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.
-- Check the DTC memory for the Driver Assistance Systems Front Camera -R242-. Fix all displayed entries.
-- Position the front wheels so they are straight.
-- 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 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 : 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 : VAS6331/1 -1- for the ACC adjustment on the : VAS6430 on the right side and tighten.
- The alignment stand must be in the lowest level position for the next step.
-- Determine height -A- between the contact surface on the : VAS6430 and the wheel contact surface as shown and enter this value into the wheel alignment computer.
- Height of calibration board for all Audi SUV models: 1400 mm + height value -A-.
- Height of calibration board for all Audi non SUV models: 1200 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.
-- Level the bubble level -A- using the adjusting screw -1-.
TIP:
The bubble level adjustment -A- serves to balance the ground conditions.
-- Slide the : VAS6430 to the side in direction of -arrows B-, until the display in the wheel alignment computer is in the tolerance range.
-- Gently turn the screws -2 and 3- to secure the : VAS6430 from rolling away.
-- Turn the fine adjustment screw -1- until the display on the wheel alignment computer is 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-.
- 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 - Adjust the calibration board to the specified height -2- according to the wheel alignment computer using the crank -1-. .
-- 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:
Vehicles with Front Camera, Version 1, MFK2
- Diagnostic-capable systems
- 00A5 - Driver Assistance Systems Control Module, MFK2
- 00A5 - Driver Assistance Systems Front Camera, Functions
- 00A5 - Calibrate control module
Vehicles with Front Camera, Version 2, MFK3
- Diagnostic-capable systems
- 00A5 - Driver Assistance Systems Control Module, MFK3
- 00A5 - Functions
- 00A5 - Calibration
-- Start the selected program and follow the instructions on the Vehicle Diagnostic Tester display.
Next, determine the height of the body.
-- Determine the dimension -a- between the center of the wheel and the lower edge of the fender/wheel housing an all four wheels, as shown.
Additional work, when the Driver Assistance Systems Front Camera -R242- was replaced:
- Adjust the headlamps. Refer to HEADLAMP, ADJUSTING .
