Infrared System, Calibrating

Special tools and workshop equipment required 

• Calibration Tool - Linear Laser VAS 6350/3 (can be used from the Calibration Tool VAS 6350)
• Setting Device Basic Set VAS 6430/1
• Night Vision Calibration Tool VAS 6430/6
• Wheel Alignment Computer

There are two choices for calibrating/adjusting:

The "Quick Access"

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

• "No or incorrect basic setting/adaptation" is stored actively in the DTC memory.
• The camera was removed or replaced,
• The bumper or the radiator grille was removed or replaced,

The "Complete Alignment"

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

• Adjustments were made on the rear axle,
• Parts of the suspension were replaced on the vehicle.

Calibration Procedure without a Previous Axle Alignment 

-- Mount the quick clamps to the rear wheels.

-- Mount the measurement sensor to the rear wheels.

-- Select the infrared system calibration procedure in the alignment computer.

Calibrating/Adjusting with a Previous Axle Alignment 

-- Connect the battery charger for the battery support mode, refer to BATTERY, STARTER, GENERATOR & CRUISE CONTROL[For engine(s) CDRA, CTUB, CEUA, CGTA, CPNA, CEJA] Battery, Starter, Generator, Cruise Control .

-- Position the front wheels so they are straight.

-- Connect the Vehicle Diagnostic Tester to the vehicle (guide the diagnostic cable through the open window).

-- Turn off all vehicle exterior lamps.

-- Close all vehicle door.

Procedure for All 

-- Connect the Vehicle Diagnostic Tester to the vehicle (guide the diagnostic cable through the open window).

-- Position the Night Vision Calibration Tool VAS 6430/6 on the center of the calibration beam of the Setting Device Basic Set VAS 6430/1.

-- The opening -arrows- must surround the nut or bolt -A- when the Night Vision Calibration Tool VAS 6430/6 is pushed onto the calibration beam.

-- Fold up the right and left bracket -A-.

-- Tighten the right and left clamping screw -1- hand-tight.

-- Set up the Setting Device Basic Set VAS 6430/1 with the Night Vision Calibration Tool VAS 6430/6 in front of the vehicle.

-- Position the Night Vision Calibration Tool VAS 6430/6 in distance -A- to the night vision system camera.

-- Attach the measuring sensor for the front wheels to the calibration beam.

• For the following work steps, the hoist must be in the lowest position -A-.

-- Insert the Linear Laser VAS 6350/3 -arrow- into the guide on the Night Vision Calibration Tool VAS 6430/6 and secure it.

-- Switch on the Linear Laser VAS 6350/3. A laser beam is beamed on the vehicle.

-- Turn the lever on the back of the calibration board to align the laser beam so that it is in the center of the camera lens in the horizontal position.

The specified height is now reached and the Linear Laser VAS 6350/3 can be switched off.

-- 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 VAS 6430/1 sideways -arrow B- until the display on the alignment computer is within the tolerance range.

-- Secure the Setting Device Basic Set VAS 6430/1 by turning the screws gently -2- and -3- (to keep the Setting Device Basic Set VAS 6430/1 from rolling away).

-- Turn the precision adjustment screw -1- on the calibration beam until the display on the alignment computer is located within the tolerance range.

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

-- Level the bubble level -B- using the adjusting screw -2-.

-- Turn the Linear Laser VAS 6350/3 back on and check the specified height and correct if necessary. A laser beam is beamed on the vehicle.

-- Turn the lever on the back of the calibration board to align the laser beam so that it is in the center of the camera lens in the horizontal position.

The specified height is now reached and the Linear Laser VAS 6350/3 can be switched off.

-- Connect the power plug -A- for the Night Vision Calibration Tool VAS 6430/6 to the power supply.

-- Turn on the switch -B- for the Night Vision Calibration Tool VAS 6430/6.
