Driver Assistance Systems Front Camera, Calibrating

Special Tools And Workshop Equipment Required 

• Setting Device Basic Set :VAS6430/1 
• Vehicle Diagnostic Tester
• Wheel Alignment Computer

There Are Two Choices for Calibrating: 

The "Quick Access"

This procedure should be selected for the following activities if only the calibration will be performed.

• "No or incorrect basic setting/adaptation" is stored actively in the DTC memory.
• The Camera Control Module -J852- was removed and installed again or replaced,
• The windshield is replaced or removed,
• The control position on vehicles with air suspension was reprogrammed.

The "Complete Alignment" 

This procedure should be selected for the following activities if a calibration and a suspension adjustment will be performed.

• The rear axle toe was adjusted.
• The vehicle suspension was changed, for example, changing from standard to sport suspension.

CALIBRATION/ADJUSTING WITHOUT A PREVIOUS AXLE ALIGNMENT 

-- Install the quick clamps on all four wheels.

-- Mount the measurement sensor to the rear wheels.

-- Perform a wheel run-out compensation and the rear wheels.

CALIBRATING/ADJUSTING WITH A PREVIOUS AXLE ALIGNMENT 

-- Position the front wheels so they are straight.

CALIBRATION/ADJUSTING PROCEDURE CONTINUATION WITH OR WITHOUT A PREVIOUS AXLE ALIGNMENT 

-- Select calibration/adjusting on the wheel alignment computer.

-- Position the :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 :VAS6430/1  as shown in the illustration.
