Preliminary Work for Calibration
Preliminary Work for Calibration
Special tools, testers and auxiliary items required
• Calibration Tool (VAS 6350)
After performing service work on the vehicle, it may be necessary to calibrate the rear view camera system anew. In detail, this is the case after:
• removing and installing rear view camera.
• replacing the rearview camera system control module.
• after repair work performed on rear lid following an accident.
• after an axle alignment.
• after performing a repair at front or rear axle.
Extensive preparatory work must be completed before the appropriate calibrating procedure can be performed using the Vehicle Diagnostic Tester. This is described in the following.
Vehicle must stand on a firm and level surface to perform the calibration. No persons may be in the vehicle interior during the measurement. Vehicle must not be moved during the measurement, opening and closing of vehicle doors is to be avoided.
Connect the Vehicle Diagnostic Tester. Refer to => [ Vehicle Diagnosis, Testing and Information Systems ] Vehicle Diagnosis, Testing and Information Systems.
- Bring the Steering Angle Sensor (G85) into 0-position (wheels straight ahead).
Overview of the assembled measuring device
1 Wheel Center Sensor (VAS 6350/1)
2 Wheel Center Sensor (VAS 6350/1)
3 Right Angle Bracket For Mounting Measuring Unit For Distance Measurement
4 Plastic Foot
• Total of three on the bottom side of measuring device
• Adjustable, for aligning horizontal position of measuring device
5 Line Laser (VAS 6350/3)
• Switching on and off => operating instructions
6 Spacing Laser (VAS 6350/2)
• Notes on operation => operating instructions
7 Fluid Level On Measuring Device
• For checking horizontal position of measuring device.
8 Left Angle Bracket For Mounting Measuring Unit For Distance Measurement
9 Calibration Tool For Lane Changing Assist (VAS 6350/4)
• Distance between the angled brackets on the calibration device (=> [ (Item 3) Right Angle Bracket For Mounting Measuring Unit For Distance
Measurement ] or => [ (Item 8) Left Angle Bracket For Mounting Measuring Unit For Distance
Measurement ] ) and the paddles on the rear wheel center wheel mounts: 1.2 m - 1.7 m - dimension A -
- Install three wheel bolt adapters (17 mm) into the holes "112" for the wheel pick-ups.
- Mount the paddles on both wheel pick-ups and secure them with the lock nuts.
- Mount the wheel pick-ups on the wheel bolts on the rear wheels. When doing this, the wheel pick-ups are positioned by the O-rings in the adapters and held in place.
• Attach the wheel pick-ups onto wheels so that any installed anti-theft wheel mounting bolts are not connected to the wheel bolt adapters.
- Adjust paddle with aid of locking nuts so that they move freely just above the floor.
Make sure the paddles move easily.
- Position the (VAS 6350/4) behind the vehicle with a distance of 1.2 m to 1.7 m (4 feet to 5.5 feet) between the angled brackets on the calibration device and the paddles at the rear wheel center wheel mounts as shown in the overview illustration - dimension A - => [ (Item 9) ].
- Bring (VAS 6350/4) to a horizontal position. To do so, twist plastic feet under calibration device so that air bubble in spirit level is located exactly in the center of the indicator - arrow -.
- Switch on the laser on the calibration device - 1 - and align the entire calibration device so that laser beam strikes on center of vehicle rear end above the VW logo.
- Turn on the (VAS 6350/2) for the distance measurement with the ON button. The following display appears and laser switches itself on:
- Hold distance laser for distance measurement - 2 - flush into angle bracket on one side of calibration device as shown in the illustration, distance laser must make contact firmly on angle bracket when doing this.
- Make sure that the laser beam from the distance laser for distance measurement contacts the paddle - 1 - at the lower, enlarged part.
If this is not the case, paddles must be corrected accordingly via clamping screws on the wheel pick-ups.
- Hold the distance laser for distance measurement firmly by the hand in the angle bracket on the measuring device while the laser beam can be seen on the paddle. Briefly press ON button for distance measurement. When doing this, the following display appears on screen:
The distance measurement is specified on the display in "meters".
- Note the value read off.
- Repeat measuring procedure in the same manner for the other rear wheel on the other side of the calibration device.
The distance value must be the same on both sides. If the value is not identical, align the calibration device only as long until the values on both sides are identical.
When aligning the calibration device, make sure the distance laser beam still strikes the center above the VW logo and indicator of fluid-level remains centered. If necessary, make further corrections accordingly.
The dimension for distance that was measured must be entered during calibration into the Vehicle Diagnostic Tester in "millimeters".
