Lane Change Assistance Control Module -J769- /Lane Change Assistance Control Module 2 -J770-, Calibrating: Notes
Special Tools And Workshop Equipment Required
- Calibration Unit:VAS6350A
CONDITIONS
-- The Lane Change Assistance Control Module -J769- / Lane Change Assistance Control Module 2 -J770- must be calibrated using the Vehicle Diagnostic Tester during the following conditions:
- Lane Change Assistance Control Module -J769- or Lane Change Assistance Control Module 2 -J770- was replaced.
- The rear bumper was damaged.
- The rear bumper cover was removed and installed.
- "No or incorrect basic setting/adaptation" is stored in the DTC memory.
PRELIMINARY WORK
-- Place vehicle on a solid, level surface.
-- Activate parking brake - vehicle must not move during measurement.
-- Place the steering wheel in the neutral position with the front wheels pointing straight ahead.
-- Connect the Vehicle Diagnostic Tester.
-- Switch on the ignition.
-- Remove the sticker with metal foil from the bumper cover if necessary.
-- Secure three fitting wheel bolt adapters for the wheel bolts to each Calibration Tool - Wheel Center Mountings -VAS6350/1-.
-- Insert the measuring paddle on both Calibration Tool - Wheel Center Mountings -VAS6350/1- and secure them with the locking nut.
-- Place the Wheel Center Mountings -VAS6350/1- onto the wheel bolts on both rear wheels.
- The wheel center mounting rotation center must be in the wheel rotation center.
Place The Calibration Tool - Wheel Center Mountings -VAS6350/1- On The Wheels So That The "Anti-Theft Wheel Bolts" Are Not Connected To The Wheel Center Mounting.
-- Adjust the measuring paddle using the locking 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 Unit:VAS6350A at distance -a- from rear wheels.
- Dimension -a- = 1, 700 mm
-- Switch on the Calibration Tool - Spacing Laser:VAS6350/2 with the ON button.
Display on the Calibration Tool - Spacing Laser:VAS6350/2 :
- "- - - m"
The Laser Is Switched On At Same Time.
-- For distance measurement, hold the Calibration Tool - Spacing Laser:VAS6350/2 -2- flush to the right catch bracket as illustrated.
- The Calibration Tool - Spacing Laser :VAS6350/2 must lie firmly against the catch bracket.
-- Make sure the "laser beam" for the distance measurement contacts the enlarged lower part on the paddle -1-.
If this is not the case, the measure paddle height must be corrected using locking nuts on Calibration Tool - Wheel Center Mountings -VAS6350/1-.
-- Briefly press the ON button for distance measurement.
Display on the Calibration Tool - Spacing Laser:VAS6350/2 :
- "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 the Calibration Unit:VAS6350A accordingly.
CALIBRATING
The Vehicle Diagnostic Tester Is Connected.
-- Select the Diagnostic mode and start the diagnosis.
-- Select the Test plan tab.
-- Press the Select individual tests button and select the following one after the other:
- 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.
The Following Information Clarifies Which Version Of The Lane Change Assistance Is Installed In The Vehicle (For Example Version SWA1.0).
This Information For Adjusting The Calibration Device Is Important For Later Steps In The Procedure To Avoid Malfunctions.
-- Secure the Calibration Tool - Lane Change Calibration Tool -VAS6350/4- at right rear of the Calibration Unit:VAS6350A mount.
- When installed correctly, the vehicle electrical system voltage wire must be connected at the bottom left of calibration device (as seen in direction of travel).
Dimension -a- is measured from the upper edge of the calibration device to the floor.

-- Connect the Calibration Tool - Lane Change Calibration Tool -VAS6350/4- to the vehicle electrical system voltage.
-- Bring Calibration Unit:VAS6350A into horizontal position by turning the plastic base.
- Observe the bubble level (sight glass) on the Calibration Unit:VAS6350A -arrow-.
-- Switch on the Calibration Tool - Linear Laser -VAS6350/3- on the Calibration Unit:VAS6350A .
-- Put on "laser protective eyewear".
-- Align the Calibration Unit:VAS6350A so that the Calibration Tool - Linear Laser -VAS6350/3- strikes the center of the brand emblem on the rear lid.
-- Check the left and right distance between the catch bracket on the Calibration Unit:VAS6350A and the measuring paddles -1- on the wheel mountings again.
- Specified value: 1700 ± 2 mm
