Lane Change Assistance Control Module -J769- AND Lane Change Assistance Control Module 2 -J770-, CALIBRATING

Special tools and workshop equipment required 

• Calibration ToolVAS6350

Conditions 

-- The Lane Change Assistance Control Module -J769- /Lane Change Assistance Control Module 2 -J770- must be calibrated in the "Guided Fault Finding" or "Guided Functions" operating mode under the following conditions 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 

-- Place vehicle on a solid, level surface.

-- Activate the parking brake - the vehicle must not move during the measurement.

-- Place the front wheels in a straight-ahead position - steering wheel in 0 position.

-- Connect the Vehicle Diagnostic Tester.

-- Turn on the ignition.

-- Remove sticker with metal foil from bumper cover if necessary.

-- Secure three wheel bolt adapters on each Calibration Tool - Wheel Center MountingsVAS6350/1.

-- Insert measuring paddle on both wheel center sensors Calibration Tool - Wheel Center MountingsVAS6350/1 and secure with lock nut.

-- Place Calibration Tool - Wheel Center MountingsVAS6350/1 on wheel bolts 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 Calibration ToolVAS6350 at distance -a- from rear wheels.

• Dimension -a- = 1, 700 mm

-- Turn on the distance laser Calibration Tool - Spacing LaserVAS6350/2 with the ON  button.

Display on Calibration Tool - Spacing LaserVAS6350/2:

• "- - - m"

-- For distance measurement, hold distance laser Calibration Tool - Spacing LaserVAS6350/2 item -2- flush to catch bracket as shown in illustration.

• The distance laser Calibration Tool - Spacing LaserVAS6350/2 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 Calibration Tool - Wheel Center MountingsVAS6350/1.

-- Briefly press ON  button for distance measurement.

Display on Calibration Tool - Spacing LaserVAS6350/2:

• "1, 700 m" (specified value: 1700 ± 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 Calibration ToolVAS6350 accordingly.

Performing Calibration 

Vehicle diagnostic tester is attached.

-- Select the Diagnostic  mode and start the diagnostics.

-- Select the tab test plan  .

-- Select select individual tests  and choose the following sequence.

• Body
• Electrical Equipment
• 01 - OBD-capable systems
• 3C - Lane change assistance control module - J769
• 3C - Lane change assistance control module, functions
• 3C - Calibration

From here the Vehicle Diagnostic Tester advances the calibration procedure forward.

-- Secure the Calibration Tool - Lane Change Calibration ToolVAS6350/4 at rear right of Calibration ToolVAS6350 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.

Adjustment Height in mm	SWA 1.0	SWA 1.5
	850	820

-- The indicator on the base of the Calibration Tool - Lane Change Calibration ToolVAS6350/4must align with setting on measurement scale -1- on measuring field -arrow-.

Right Adjustment Dimension in mm	SWA 1.0	SWA 1.5
	706	790
Read on the measuring scale -1-.

-- Connect the Calibration Tool - Lane Change Calibration ToolVAS6350/4 to vehicle electrical system voltage.

-- Bring Calibration ToolVAS6350 into horizontal position by turning plastic base.

• Observe bubble level (sight glass) on Calibration ToolVAS6350 -arrow-.

-- Switch Calibration Tool - Linear LaserVAS6350/3 on Calibration ToolVAS6350 on.

-- Put on "Laser eye protection".

-- Align Calibration ToolVAS6350 so that Calibration Tool - Linear LaserVAS6350/3 hits center of wiper shaft on rear window.

-- Check left and right distance between catch bracket on Calibration ToolVAS6350 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 radius of the calibration device (i.e. 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 Calibration Tool - Lane Change Calibration ToolVAS6350/4.

Procedure 

-- Switch the Calibration Tool - Lane Change Calibration ToolVAS6350/4 on at power switch -3-.

• The green LED -1- must light up.

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

During the course of the program, a request is made to switch the Calibration Tool - Lane Change Calibration ToolVAS6350/4 from the right to the left side of the Calibration ToolVAS6350.

-- Switch the Calibration Tool - Lane Change Calibration ToolVAS6350/4 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.
