Side Assist, Calibrating
The left Lane Change Assistance Control Module (J769) (master) or right Lane Change Assistance Control Module 2 (J770) (slave) is combined into one unit with the radar sensor for the respective side. They are located behind the rear bumper cover and must be calibrated after:
• removal and installation of the bumper cover
• removal and installation of one or both lane change assistance control modules
• each time the installation location of a lane change assistance control module is changed
Before the calibration procedure can be performed with the Vehicle Diagnosis, Testing and Information System (VAS 5051B), considerable preparation work must be performed --> [ Preliminary Work for Calibration ].

Preliminary Work for Calibration
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
• Activate 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
Special tools, testers and auxiliary items required
• Vehicle Diagnostic, Testing and Information System with diagnostic cable (VAS 5051/5 A)
• Calibration Device (VAS 6350)
- Connect Vehicle Diagnosis, Testing and Information System (VAS 5051B) with Diagnostic Cable (VAS 5051/5 A).
• If a malfunction indication is displayed --> 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± 0.08 in.
- Switch distance laser (VAS 6350/2) on with 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.
- Ensure "laser beam" for distance measurement hits the lower enlarged portion of the measuring paddle - 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: 1700 ± 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 = 30.43 in (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: 1700 ± 0.08 in
