Driver Assistance Systems Front Camera, Calibrating, AUDI Q7
Special tools and workshop equipment required
- Vehicle Diagnostic Tester
- Wheel Alignment Computer
- Setting Device - Basic Set: VAS6430/1A
- Adapter VAS6430/9 : VAS6430/9 , only for surface mounted hoist with a dimension greater than 300 mm.
Procedure
- For surface mounted hoist with a dimension greater than 300 mm the : VAS6430/1A with the : VAS6430/9 must be set higher.
- Check the DTC memory and correct any malfunctions before beginning the calibration.
-- 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 of the visible area of the Driver Assistance Systems Front Camera -R242- is free.
-- "Activate wheel change mode" on equipment versions with air suspension. Refer to the Owner's Manual or "Standard Vehicle Height, Initiating and Locking". Refer to STANDARD VEHICLE HEIGHT, INITIATING AND LOCKING .
There Are Two Choices for Calibrating:
The "Quick Access"
This procedure should be selected for the following activities if only the calibration will be performed.
- "No or incorrect basic setting/adaptation" is stored actively in the DTC memory.
- the Driver Assistance Systems Front Camera -R242- was removed and installed or replaced,
- the windshield is replaced or removed,
- The standard vehicle height on versions with air suspension was reprogrammed.
The "Complete Alignment"
This procedure should be selected for the following activities if a calibration and a wheel alignment will be performed.
- The rear axle toe was adjusted.
- the vehicle suspension was changed, for example, changing from standard to Sport suspension.
- 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.
Calibrating Without a Previous Axle Alignment
- Switch off the ignition when the vehicle has come to a stop. This is the only way to ensure that the rear axle steering is in the straight-ahead position.
-- Select the front camera calibration procedure in the alignment computer.
-- Install quick-action clamps on the wheels.
-- Install the measuring sensors on the wheels.
-- Carry out wheel run-out compensation.
Calibrating With a Previous Axle Alignment
- Switch off the ignition when the vehicle has come to a stop. This is the only way to ensure that the rear axle steering is in the straight-ahead position.
-- Connect the battery charger. Refer to BATTERY, CHARGING .
-- Position the front wheels so they are straight.
-- Connect the Vehicle Diagnostic Tester to the vehicle and guide the diagnostic cable through the open window.
-- Turn off all vehicle exterior lamps.
-- Close all vehicle doors.
Calibrating/Adjusting Procedure with or Without a Previous Axle Alignment
-- Select the front camera calibration procedure in the alignment computer.
-- 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 as shown in the illustration.
- The : VAS6430/1A must not be moved on the calibration beam.
-- Mount the front wheel measuring sensors -1- to the : VAS6430/1A .
- The alignment stand must be in the lowest level position for the next step.
-- Enter the height value -A- between the : 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: 1400 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-.
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-.
The bubble level adjustment -A- serves to balance the ground conditions.
-- Move the : VAS6430/1A sideways -arrow B- until the display on the alignment computer is within the tolerance range.
-- Secure the : VAS6430/1A by tightening the bolts -2- and -3- slightly. (This prevents the : VAS6430/1A 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-.
-- Balance the bubble level -B- using the adjusting screw -2-.
- 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, AUDI Q7 - Adjust the calibration board to the specified height -2- .
Perform Any Subsequent Work Using the Vehicle Diagnostic Tester.
-- 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:
- Body
- Electrical system
- 01 - OBD-capable systems
- A5 - Driver Assistance Systems Front Camera -R242
- A5 - Driver Assistance Systems Front Camera Functions
- A5 - Control module calibrating
-- Start the selected program and follow the instructions on the Vehicle Diagnostic Tester display.
-- Determine the body height -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.
