Preliminary Work

• Move the vehicle onto a solid, flat surface.
• Move the wheels so that they are in a straight-ahead position.
• For vehicles with rear axle steering, steer the rear axle to the zero position. Refer to Rear Axle Steering . This is the only way to ensure that the rear axle steering is in the straight-ahead position.
• Vehicles without air suspension: deflect the springs several times and let settle.
• Electromechanical parking brake applied.
• Clean the camera lens on the Rearview Camera -R189-.
• All vehicle doors closed.
• Connect the battery charger for the battery support mode. Refer to BATTERY, CHARGING .
• Before starting the calibration/adjustment, check the DTC memory and correct all displayed entries.

Procedure 

-- Check which hole circle the rims have.

-- Secure three suitable wheel bolt adapters for the wheel bolts on each Calibration Tool - Wheel Center Mountings: VAS6350/1A  .

-- Insert the measuring paddle at both Calibration Tool - Wheel Center Mounting: VAS6350/1A  and secure with the locking nut.

-- Place the Calibration Tool - Wheel Center Mountings: VAS6350/1A  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 Mounting: VAS6350/1A  on the wheels so that any "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 Tool: VAS6350A  at distance -a- to the rear wheels.

• Dimension -a- = 1.40 to 2.00 m

-- Using the bubble level (level indicator) -arrow-, bring the Calibration Tool: VAS6350A  into a horizontal position by turning the plastic bases.

-- Wear "laser protective eyewear".

-- Turn on the Calibration Tool - Linear Laser: VAS6350/3A  -1- on the Calibration Tool: VAS6350A  .

-- Align the Calibration Tool: VAS6350A  so that the Calibration Tool - Linear Laser: VAS6350/3A  -1- strikes the center of the brand emblem on the rear lid.

Distance measurement of Calibration Tool: VAS6350A  to rear wheels:

-- Switch on the Calibration Tool - Spacing Laser: VAS6350/2A  .

• -arrow 1- : position with front edge
• -arrow 3- : position with rear edge

-- Press the corresponding button.

-- Hold the Spacing Laser: VAS6350/2A  -2- for the distance measurement on one side of the calibration board flush to the catch bracket, as shown.

• The Calibration Tool - Spacing Laser: VAS6350/2A  -2- must lie firmly against the catch bracket.

-- Push the measurement button briefly.

The laser switches on.

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

If that is not the case, then correct the measuring paddle -1- height using the clamping screw on the Calibration Tool - Wheel Center Mounting: VAS6350/1A  .

-- Use one hand to hold the Calibration Tool - Spacing Laser : VAS6350/2A  firmly in the catch bracket on the Calibration Tool: VAS6350A  ; the laser beam should be seen on the measuring paddle during this.

-- Then press the measurement button for the distance measurement briefly.

-- Note the value.

-- Repeat this measurement on the other side of the Calibration Tool: VAS6350A  in the same way for the rear wheel.

• The distance value must be the same on both sides.

-- If both measured values are not the same, then readjust the Calibration Tool: VAS6350A  correspondingly until the distance values are the same on both sides.

-- Make sure the Calibration Tool - Line Laser: VAS6350/3A  strikes the center above the brand emblem and that the level indicator remains centered. Adjust if necessary.

Distance measurement of Calibration Tool: VAS6350A  to the workshop floor:

-- Measure the distance from the upper edge of the Calibration Tool: VAS6350A  to the floor, dimension -a-.

-- Make sure the Calibration Tool - Spacing Laser: VAS6350/2  is set correctly (attached to the front edge).

The display -2- shows how to position the Calibration Tool - Spacing Laser: VAS6350/2A  .

• -arrow 1- : position with front edge
• -arrow 3- : position with rear edge

-- Press the corresponding button.

-- Then press the measurement button for the distance measurement briefly.

-- Note the measured distance from the upper edge of the Calibration Tool: VAS6350A  to the floor.

Height measurement from center of rearview camera lens to the wheel contact surface:

-- Use commercially available measuring tape to measure the height from the center of the rearview camera lens to the wheel contact surface.

-- Mark the determined height.

The determined distance and height dimensions must now be entered in "millimeters" in the Vehicle Diagnostic Tester.

Calibration Procedure

The following should not occur during the calibration procedure:

• Vehicle doors must not be opened or closed.
• People must not sit in the vehicle.
• Vehicle must not be loaded (curb weight).

-- Connect the Vehicle Diagnostic Tester.

-- Switch the ignition on.

-- Select and start the Diagnostic  operating mode.

-- Select the Test plan  tab.

-- Select the Select individual test  button and select the following tree structure consecutively:

• Diagnostic-capable systems
• 006C - Rearview Camera System Control Module - J772
• 006C - Rearview Camera System Control Module, functions
• 006C - Calibrating

-- Start the selected program and follow the instructions on the Vehicle Diagnostic Tester display.

-- Switch off the ignition after successful calibration/adjustment.

-- Disconnect the Vehicle Diagnostic Tester from the diagnostic connection.

-- Disconnect the battery charger. Refer to BATTERY, CHARGING .
