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

-- Connect the Vehicle Diagnostic Tester using the Vehicle Diagnostic Tester.

NOTE:

If a malfunction message appears in the display. Refer to the Vehicle Diagnostic Tester Operating Instructions.

-- Turn on the ignition.

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

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

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

-- Place the Calibration Tool - Wheel Center MountingsVAS6350/1 onto the wheel bolts on both rear wheels.

The wheel center sensor rotation center must be in wheel rotation center.

NOTE:

Place the Calibration Tool - Wheel Center MountingsVAS6350/1 on wheels so that "anti-theft wheel bolts" are not connected with wheel center mounting.

-- Adjust the measuring paddle with the aid of the 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 ToolVAS6350 at distance -a- from rear wheels.

NOTE:

The laser is switched on at same time.

-- For distance measurement, hold the Calibration Tool - Spacing LaserVAS6350/2 -2- flush to the right stop bracket as illustrated.

The Calibration Tool - Spacing LaserVAS6350/2 must lie firmly against the catch bracket.

-- Make sure the "laser beam" for the distance measurement contacts the paddle on the lower enlarged part -1-.

If this is not the case, measure paddle height must be corrected using locking nuts on Wheel Center MountingVAS6350/1.

-- Briefly press the ON button for distance measurement.

Display on the 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 the Calibration ToolVAS6350 accordingly.

Performing calibration

Vehicle Diagnostic Tester is attached.

-- Choose operation mode Diagnosis and start the diagnosis.

-- 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

The Vehicle Diagnostic Tester continues with the calibrating procedure from here on.

NOTE:

The following information clarifies which version of the lane change assistance is installed (version SWA1.7).

This information for adjusting the calibration tool is important for later steps in the procedure to avoid malfunctions.

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