Lane Change Assistance Control Modules -J769- / -J770-, Calibrating

Special tools and workshop equipment required 

• Calibration Tool For Lane Changing AssistVAS 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 using the Vehicle Diagnostic Tester:

• 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

-- Move the vehicle onto a solid, flat surface.

-- Set the parking brake - the vehicle must not move during the measuring.

-- Move the front wheels so they are pointing straight ahead - the steering wheel is in the neutral position.

-- Connect the Vehicle Diagnosis Tester.

-- Switch ignition on.

-- Remove the label with the metal foil from the bumper cover, if necessary.

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

-- Insert the measuring paddle on both wheel center sensors -VAS 6350/1- and secure it with the locking nut.

-- Place the -VAS 6350/1- on the wheel bolt on both rear wheels.

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

-- 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 the Calibration ToolVAS 6350 at distance -a- to the rear wheels.

• Dimension -a- = 1700 mm

-- Turn on the spacing laser VAS 6350/2 with the ON  button.

Display on VAS 6350/2:

• "- - - m"

-- For distance measurement, hold the distance laser VAS 6350/2 -2- flush to the left 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 the measuring procedure from the right stop bracket to the right 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 path "calibration" after selecting "lane change assistance".

-- Secure lane change assistance calibration device -VAS 6350/4- at left rear 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.

Height Adjustment Dimension	mm
SWA 1.5	830 (32.67 in)
SWA 1.7	830 (32.67 in)

-- 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-.

Left Adjustment Dimension	mm
SWA 1.5	790 (31.1 in.)
SWA 1.7	790 (31.1 in.)
Read on the measuring scale -1-.

-- Connect the calibration tool for lane changing assist -VAS 6350/4- to the vehicle electrical system voltage.

-- Bring VAS 6350 into horizontal position by turning plastic base.

• Observe bubble level (sight glass) on VAS 6350 -arrow-.

-- Turn on the Line laser -VAS 6350/3- on the VAS 6350.

-- Wear "laser protective eyewear".

-- 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: 1, 700 ± 2 mm

Calibration procedure

The following should not occur during the calibration procedure:

• No metal reflectors may be located within a 2 m (6.5 ft.) radius of the calibration device (such as tool carts, metal cabinets).
• 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

-- Turn on the calibration tool for lane changing assist -VAS 6350/4- on the voltage switch -3-.

• The green LED -1- must light up.

-- Follow the instructions in 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 left to the right side of the VAS 6350.

-- Turn off the calibration tool for lane changing assist -VAS 6350/4- and remove the calibration tool.

• 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.

• The green LED -1- must light up.

-- Follow the instructions in the Vehicle Diagnosis Tester display.

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