Preliminary Work for Calibration

Preliminary Work for Calibration

Special tools, testers and auxiliary items required

• Vehicle Diagnostic, Testing and Information System with Diagnostic Cable (VAS 5051/5 A)

• Calibration Tool For Lane Changing Assist (VAS 6350)

Before the calibration procedure can be performed with the Vehicle Diagnosis, Testing and Information System , considerable preparation work must be performed.

Requirements

• Place vehicle on a solid, level surface

• Set the parking brake - vehicle must not move during measurement

• Place front wheels in straight-ahead position - steering wheel in 0 position

• On vehicles with air suspension, set vehicle height to middle position (display in instrument cluster display)

• Remove sticker with metal foil from bumper cover if necessary

• No persons may be in the vehicle interior during the measurement

• Do not open and close the vehicle doors during calibration

- Connect (VAS 5051B) with (VAS 5051/5 A).

• If a malfunction indication is displayed, refer to the Operating instructions of (VAS 5051B).

- Switch on ignition.

- Secure three SW 19 wheel bolt adapters for wheel bolts on each Wheel Center Sensor (VAS 6350/1).






- Insert measuring paddle on both wheel center sensors (VAS 6350/1) and secure with lock nut.

- Place Wheel Center Sensor (VAS 6350/1) on wheel bolts on both rear wheels.

• Wheel center sensor rotation center must be in wheel rotation center.

• Place Wheel Center Sensor (VAS 6350/1) on wheels so that "anti-theft wheel bolts" are not connected with wheel center sensor.

- Adjust measuring paddle with aid of lock nuts so that they move freely just above the floor.

• The measuring paddles must move easily.

• The measuring paddles must be vertical.

- Position Calibration Device (VAS 6350) at distance - a - from rear wheels.






• Dimension - a - = 1700 ± 2 mm.

- Turn on the distance laser (VAS 6350/2) with the ON button.






Display on (VAS 6350/2) :

• "- - - m"

• Laser is switched on at same time.

- Hold the distance laser (VAS 6350/2) - 2 - flush against the catch bracket, as shown in the illustration, for the distance measurement.






• The distance laser (VAS 6350/2) lie firmly against catch bracket.

- Make sure the "laser beam" for the distance measurement contacts the paddle on lower enlarged part - 1 -.

If this is not the case, measure paddle height must be corrected using lock nuts on Wheel Center Sensor (VAS 6350/1).

- Briefly press ON button for distance measurement.






Display on (VAS 6350/2) :

• "1,700 m" (specified value: 1,700 +/- 2 mm).

- Repeat measurement procedure from left catch bracket to measurement paddle on left rear wheel.

• The distance value must be the same on both sides.

If both measured values are not the same, adjust Calibration Device (VAS 6350) accordingly.

- Secure lane change assistance calibration device (VAS 6350/4) at left rear of Calibration Device (VAS 6350) mount.






• When installed correctly, vehicle electrical system voltage line must be connected at bottom left of calibration device (as seen in direction of travel).

• Dimension - a - = 850 mm (measured from upper edge of calibration device to workshop floor).

- The adjustment dimension is set with the measuring point - arrow - on the base of the calibration device on the scale of the steel ruler - 1 -.

• Left setting = 773 mm (read on measurement scale - 1 -).

- Connect lane change assistance calibration device (VAS 6350/4) to vehicle electrical system voltage.

- Using the bubble level (level indicator) - arrow -, bring the Calibration Device (VAS 6350) into a horizontal position by turning the plastic bases.






- Put on Laser eye protection.






- Switch Line Laser (VAS 6350/3) on Calibration Device (VAS 6350) on.

- Align the entire Calibration Device (VAS 6350) so that the laser beam shines on the center of the vehicle rear above the VW logo.

- Check right and left distance between catch bracket on Calibration Device (VAS 6350) and measuring paddle - 1 - on wheel sensors again.






• Specified value: 1,700 ± 2 mm
