Preliminary Work for Calibration







Preliminary Work for Calibration

Special tools, testers and auxiliary items required

Vehicle Diagnosis, Testing and Information System (VAS 5051B)

Calibration tool for lane changing assist (VAS 6350)

Preparations must be made before the calibration procedure can be performed with the Vehicle diagnosis, testing and information system (VAS 5051B).

Requirements

Place vehicle on a solid, level surface.

Engage the parking brake - the vehicle must not move during calibration.

On vehicles with air suspension, set the suspension height to "Auto" while the engine is running. Then turn on vehicle lift mode. Refer to Maintenance Procedures; Rep. Gr. 03 (the level control system is off).

No persons may be in the vehicle interior during the calibration.

Do not open and close the vehicle doors during calibration.

Make sure the vehicle is at curb weight *.

* Curb weight means: the weight of the vehicle when it is ready for driving (full fuel tank, spare wheel, vehicle tool kit, vehicle jack).

- Connect the (VAS 5051B).

- Check which hole circle the rims have.

- Install the wheel pick-ups which fit the Touareg: For this purpose, secure three adapters for wheel mounting bolts for Touareg on the hole circle with designation "120" or "130" on each wheel pick-up.

- Attach paddles to both wheel pick-ups (VAS 6350/1) and secure them with clamping screw.

- Place Wheel Center Sensor (VAS 6350/1) on wheel bolts on rear wheels. When doing this, the wheel pick-ups are positioned by the O-rings in the adapters and held in place.






Attach wheel pick-ups onto wheels so that any installed anti-theft wheel mounting bolts are not connected to the wheel pick-ups.

- Set the paddles via the clamping screw so that they are free to move just above the ground.

Make sure paddles move easily.

- Position the Calibration tool for lane changing assist (VAS 6350/4) behind the vehicle with a distance of 1.2 m to 1.7 m 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 4) ] Preparing for Calibration.

- 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 Spacing laser (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 hand in the angled bracket on the calibration device with the laser beam visible 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 line laser beam still strikes the center above the VW logo and the indictor in the level stays centered. If necessary, make further corrections accordingly.






- Measure the height of the calibration device, dimension - H - (top edge platform - floor).

The distance dimension that was measured, the height of the calibration device and the height of the center of the rearview camera lens must be entered in the (VAS 5051B) in millimeters during calibration.
