Calibration Procedure

Special Tools And Workshop Equipment Required

Vehicle Diagnostic Tester with Corresponding Diagnostic Cable
Setting Device Basic Set VAS6430/1
Wheel Alignment Computer

NOTE:

Check if the Setting Device Basic Set VAS6430/1 is in the center position and is locked.

Check if the Directional Stabilization Assistance Control Module -J759- is seated in the bracket correctly.

Perform a visual inspection to see if the camera visual area is free.

Check the DTC memory and correct any malfunctions before beginning the calibration.

Before driving the vehicle onto the alignment stand, check if there is a enough space between the center of the wheel hub on the front wheels and the Setting Device Basic Set VAS6430/1. The distance between the Setting Device Basic Set VAS6430/1 and the center of the wheel hub on the front wheels must be 150 cm ± 2.5 cm.

If there is not enough space, drive vehicle the backward on the alignment stand in order to be able to use the space.

Check the position of the calibration board on the calibration beam and align it with the center of the board if necessary.

-- Follow the test requirements for an axle alignment, refer to VEHICLE ALIGNMENT TEST REQUIREMENTS .

-- Connect the battery charger, refer to BATTERY, CHARGING .

-- Connect the Vehicle Diagnostic Tester to the vehicle. (Guide the diagnostic cable through the door window.)

NOTE:

During the calibration procedure, make sure all the vehicle doors remain closed and the vehicle exterior lighting is switched off.

-- Position the front wheels so they are straight.

-- Select the lane assist calibration procedure in the alignment computer.

-- Install the quick clamps on all four wheels.

-- Install measuring sensors on the rear wheels.

-- Perform a rim run-out compensation on the rear wheels.

NOTE:

The Setting Device Basic Set VAS6430/1 must not be moved on the calibration beam.

-- Position the Setting Device Basic Set VAS6430/1 at a distance of -A- 150 cm ± 2.5 cm from the center of the wheel hub on the front wheels to the beam on the Setting Device Basic Set VAS6430/1 as shown in the illustration.

NOTE:

The alignment stand must be in the lowest level position for the next step.

-- Enter the height value -A- between the Setting Device Basic Set VAS6430/1 contact patch and the wheel contact surface as shown in the illustration and enter it in the alignment computer.

If the specified height was reached -2-, then the measuring bar must be pushed slightly upward and secured with the clamping screw.

NOTE:

If in later procedure the height of the calibration board must be corrected, make sure the measuring bar is touching the ground when this is being done.

-- Level the bubble level -A- using the adjusting screw -1-.

The bubble adjustment -A- serves to compare the ground conditions.

-- Move the Setting Device Basic Set VAS6430/1 sideways -arrow B- until the display on the alignment computer is within the tolerance range.

Subsequent procedures are performed using the Vehicle Diagnostic Tester.

-- Turn on the ignition.

-- Touch Guided Fault Finding .

-- Select in succession:

Brand
Type
Model year
Version
Engine code

-- Confirm data entered.

Wait until the Vehicle Diagnostic Tester has check all the control modules in the vehicle.

-- Press the go to button and select "function/component selection".

-- Select the corresponding program in "Guided Functions".

Now follow the instructions on the screen to perform the calibration.

NOTE:

A step is performed in Guided Fault Finding next to determine the body height.

-- Determine the body height -a- at all four wheels in the center of the wheel between the wheel contact surface and the lower edge of the fender.
