Driver Assistance Systems Front Camera, Calibrating: Procedure
The procedure is described for a John Bean V3D Aligner -VAS6331-.
- Note the test requirements. Refer to Test Requirements.
- Measurement Preparations for Calibrating and Adjusting Driver Assistance Systems. Refer to Measurement Preparations for Calibrating/Aligning the Driver Assistance Systems, Quick Access Mode.
- Check if the Setting Device Basic Set - VAS 6430/1- 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.
- Drive the vehicle "straight" onto the alignment rack. Switch off the ignition when the vehicle has come to a stop.
- 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.
- Mount the reflectors on 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-, as shown.
1 - Measuring tape
- The -VAS6430/1A- must not be moved on the calibration beam.
- Place the Camera -VAS6331/1- -item 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.
- 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.
- 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.
- 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.
- 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
The bubble level adjustment -A- serves to balance the ground conditions.
- Move the -VAS6430/1A- at the sides in direction of -arrows B- until the display on the alignment computer is within the tolerance range.
- Secure the setting device basic set -VAS 6430/1A- by tightening the bolts -2 and 3- slightly. (This prevents 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-.
- Level the bubble level -A- using the adjusting screw
NOTE:
Because small height changes can result after adjusting the bubble levels, the height of the calibration board must be checked again.
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
- 0001 - OBD-capable systems
- 00A5 - Driver Assistance Systems Front Camera - R242
- 00A5 - Driver Assistance Systems Front Camera functions
- 00A5 - Calibrate control module
- Start the selected program and follow the instructions on the Vehicle Diagnostic Tester display.
Next, determine the height of the body.
- 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.
