Lane Change Assistance Control Modules (J769)/(J770), Calibrating






Lane Change Assistance Control Modules (J769)/(J770), Calibrating

Special tools, testers and auxiliary items required

• Calibration Tool For Lane Changing Assist (VAS 6350)

• Vehicle Diagnosis, Testing & Information System (VAS5051B)

Conditions

- The lane change assistance control modules (J769) / (J770) must be calibrated in the "Guided Fault Finding" or "Guided Functions" operating mode under the following conditions using the (VAS5051B) :

• The lane change assistance control module or lane change assistance control module 2 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 (VAS5051B).

• If a malfunction message appears in the display, refer to the (VAS5051B)

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






• Dimension - a - = 1,700 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.

- For distance measurement, hold distance laser (VAS 6350/2) - item 2 - flush to catch bracket as shown in illustration.






• 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.

• Vehicles with SWA1.0: Dimension - a - = 850 mm

• Vehicles with SWA1.5: Dimension - a - = 820 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 -.

Vehicles with SWA1.0:

• Right setting = 706 mm (read on measurement scale - 1 -).

Vehicles with SWA1.5:

• Right setting = 790 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 (VAS 6350) so that Line Laser (VAS 6350/3) hits center of wiper shaft on rear window.

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






• Specified value: 1,700 ± 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 Calibration Device (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.

• Vehicles with SWA1.0: Dimension - a - = 850 mm

• Vehicles with SWA1.5: Dimension - a - = 820 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 -.

Vehicles with SWA1.0:

• Left setting = 706 mm (read on measurement scale - 1 -).

Vehicles with SWA1.5:

• Left setting = 790 mm (read on measurement scale - 1 -).

All Vehicles






- Switch lane change assistance calibration device (VAS 6350/4) on at power switch - 3 -.

• The green LED - 1 - must light up.

- Follow the instructions on the Vehicle Diagnosis Tester display.

- After calibrating the lane change assistance successfully, end "calibration", switch off the ignition and disconnect the diagnostic connector.
