Preliminary Work for Calibration
Preliminary Work for Calibration
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 vehicle diagnostic tester. Refer to => [ Vehicle Diagnosis, Testing and Information Systems ] Vehicle Diagnosis, Testing and Information Systems
- Move the steering angle sensor (G85) into the 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 Line Laser (VAS 6350/3)
• Switching on and off => operating instructions
5 Plastic Foot
• Total of three on the bottom side of measuring device
• Adjustable, for aligning horizontal position of measuring device
6 Spacing Laser (VAS 6350/2)
• Notes on operation, refer to the 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 device (VAS6350/4)
• 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 -
- Secure the holed circle "112" on the wheel center sensor with the 3 wheel bolt adapter (17 mm).
- Place the paddles on both wheel center sensors and secure them with locking nuts.
- Place the wheel center sensor 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 the paddle with aid of lock nuts so that they move freely just above the floor.
• Make sure the paddle moves easily.
• The paddles must return to a vertical position by themselves.
- Position the calibration device (VAS 6350/4) behind the vehicle as illustrated in the overview illustration - dimension A -, item 9=> [ (Item 9) ] 1.20 m - 1.70 m between the brackets on the calibration tools and the paddles on the wheel center sensor on the rear wheels.
- Move the calibration device (VAS 6350/4) in a horizontal position. Twist plastic feet under calibration platform so that air bubble in the level is located exactly in the center of the indicator - arrow -.
- Turn on the laser on the calibration tool - 1 - and align the entire calibration tool so that the laser beam - 2 - is pointed on the center of the rear lid above the VW logo.
- Turn on the spacing laser (VAS 6350/2) for the distance measurement using 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".
- Write down the distance measured.
- Repeat this measurement on the other side of the calibration tool in the same way for the other rear wheel.
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 line laser beam still strikes the center above the VW emblem and the indicator on the level is still centered. Adjust if necessary.
The dimension for distance that was measured must be entered during calibration into the Vehicle Diagnostic Tester or in "millimeters".
