Lane Change Assistance Control Modules, Calibrating
Special tools, testers and auxiliary items required
• Calibration tool for lane changing assist (VAS 6350)
Conditions
- The lane change assistance control module (J769)/ (J770) must be calibrated in the Guided Fault Finding or Guided Functions operating mode under the following conditions
• The lane change assistance control module (J769) or lane change assistance control module 2 (J770) was replaced.
• The rear bumper was damaged.
• The rear bumper was removed and installed.
• The DTC no or incorrect basic setting/adaptation is stored in the DTC memory.
Procedure
- 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.
- Connect the Vehicle Diagnosis Tester.
• If a malfunction message appears in the display, refer to the vehicle diagnosis tester operating instructions.
- Switch on ignition.
- Remove sticker with metal foil from bumper cover if necessary.
- 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 (VAS 6350/1) on wheel bolts on both rear wheels.
• Wheel center sensor rotation center must be in wheel rotation center.
• Place (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 (VAS 6350) at distance - a - from rear wheels.
• Dimension - a - = 1,700 mm
- Switch distance laser (VAS 6350/2) on with ON button.
Display on (VAS 6350/2)
• - - - m
• Laser is switched on at same time.
- For distance measurement, hold the distance laser (VAS 6350/2) - item 2 - flush to the stop bracket as illustrated.
• 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 (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 left rear wheel.
• The distance value must be the same on both sides.
If both measured values are not the same, adjust (VAS 6350) accordingly.
- Select the function or path.
• The version of the lane change assistance software is displayed (versions SWA1.0 or SWA1.5).
• This information for adjusting the calibration device is important for later steps in the procedure to avoid malfunctions.
- Secure lane change assistance calibration device (VAS 6350/4) at rear right of (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 - is measured from upper edge of calibration device to the floor.
• 2-door dimension - a - = 700 mm
• 5-door dimension - a - = 800 mm
- The indicator on the base of the lane change assistance calibration device (VAS 6350/4) must align with setting on measurement scale - 1 - on measuring field - arrow -.
2-door with SWA1.0
• Right setting = 586 mm (read on measurement scale - 1 -).
2-door with SWA1.5
• Audi A5 right setting = 745 mm (read on measurement scale - 1 -).
• Audi RS 5 right setting = 590 mm (read on measurement scale - 1 -).
5-door with SWA1.5
• Right setting = 690 mm (read on measurement scale - 1 -).
All Vehicles
- Connect lane change assistance calibration device (VAS 6350/4) to vehicle electrical system voltage.
- Bring (VAS 6350) into horizontal position by turning plastic base.
• Observe bubble level (sight glass) on (VAS 6350) - arrow -.
- Switch (VAS 6350/3) on (VAS 6350) on.
- Put on Laser eye protection.
- Align the (VAS 6350) so the (VAS 6350/3) strikes the center of the brand emblem on the rear lid.
- Check left and right distance between catch bracket on (VAS 6350) and measuring paddle - 1 - on wheel sensors again.
• Specified value 1700 ± 2 mm
Calibration procedure
The following should not occur during the calibration procedure.
• Vehicle doors must not be opened or closed.
• People should not sit in the vehicle.
• People should not go between the vehicle and the lane change assistance calibration device (VAS 6350/4).
Procedure
- Switch lane change assistance calibration device (VAS 6350/4) on at power switch - 3 -.
• The green LED - 1 - must light up.
• If the red LED - 2 - lights up, check lane change assistance calibration device (VAS 6350/4).
- Follow the instructions on the Vehicle Diagnosis Tester display.
During the course of the program, a request is made to switch the lane change assistance calibration device (VAS 6350/4) from the right to the left side of the (VAS 6350).
- Switch lane change assistance calibration device (VAS 6350/4) off and move device.
• 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 - is measured from upper edge of calibration device to the floor.
• 2-door dimension - a - = 700 mm
• 5-door dimension - a - = 800 mm
2-door with SWA1.0
• Left setting = 586 mm (read on measurement scale - 1 -).
2-door with SWA1.5
• Audi A5 left setting = 745 mm (read on measurement scale - 1 -).
• Audi RS 5 left setting = 590 mm (read on measurement scale - 1 -).
5-door with SWA1.5
• Left setting = 690 mm (read on measurement scale - 1 -).
All Vehicles
- Switch lane change assistance calibration device (VAS 6350/4) on at power switch - 3 -.
