Night Vision System Camera (R212), Adjusting and Calibrating
Night Vision System Camera (R212), Adjusting and Calibrating
Special tools, testers and auxiliary items required
• Vehicle Diagnostic Tester with its diagnostic cable
• Setting Device Basic Set (VAS 6430/1) or Setting Device (VAS 6430)
• Line Laser (VAS 6350/3) (can be used from the Calibration Tool (VAS 6350) )
• Enhanced Night Vision Calibration Unit (VAS 6430/6)
• Wheel Alignment Computer
• Make sure the night vision system camera fits correctly in the bracket and the viewing range for the camera is not blocked.
• Make sure the protective window on the infrared camera is not chipped. Replace it if necessary. Refer to => [ Night Vision System Camera (R212) ] Night Vision System Camera (R212).
• If the vehicle has adaptive cruise control and infrared system, then the infrared system must be adjusted/calibrated first and after that can the adaptive cruise control be adjusted.
• Remove the (VAS 6430/3) if is located on the calibration beam of the (VAS 6430/1) or (VAS 6430).
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 Diagnostic Trouble Code (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 suspension.
• Parts of the suspension were replaced on the vehicle.
• Both procedures are programmed into the axle alignment computer. The respective procedure is performed automatically. It is only necessary to select the appropriate program for the procedure that will be performed.
Preparation work for calibrating and adjusting driver assist systems, refer to => [ Preparation Work for Calibrating and Adjusting Driver Assist Systems ] Preparation Work For Calibrating and Adjusting Driver Assist Systems.
Calibration Procedure without a Previous Wheel 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 Wheel Alignment
- Connect the battery charger.
- Position the front wheels so they are straight.
- Connect the vehicle diagnostic tester to the vehicle and 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 door window.)
- Position the (VAS 6430/6) on the center of the calibration beam of the (VAS 6430/1).
- The opening - arrows - must surround the nut and bolt - A - when the (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 (VAS 6430/1) and the (VAS 6430/6) in front of the vehicle.
- Position the (VAS 6430/6) in distance - A - to the infrared camera.
• Distance - A - = 120 cm +/- 2.5 cm, measured between the (VAS 6430/6) and the lens on the infrared 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 -.
- Install and secure the (VAS 6350/3) - arrow - into the guide in the (VAS 6430/6).
- Switch on the (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 (VAS 6350/3) can be turned off.
- Level the bubble level - A - using the adjusting screw - 1 -.
The bubble adjustment - A - serves to compare the ground conditions.
- Move the (VAS 6430) sideways - arrow B - until the display on the alignment computer is within the tolerance range.
- Secure the (VAS 6430) by tightening the bolts - 2 and 3 - slightly. (This prevents the (VAS 6430) 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 (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 (VAS 6350/3) can be turned off.
- Connect the network connector - A - from the (VAS 6430/6) to the current network.
- Turn on the switch - B - on the (VAS 6430/6).
• An internal initialization takes place after turning on the (VAS 6430/6). Both LEDs - C - blink at the same time and an acoustic tone will sound if the initialization is successful and was performed without any faults. After this, the (VAS 6430/6) is in the ready mode. The green LED will blink slowly.
• Check the bubble level and correct the adjustment if necessary.
- Push the button - A - to activate the heating function.
An acoustic signal will sound when the heating function is activated. The heat-up phase has begun.
As soon as the specified temperature is reached, the green LED will stay on.
The heating elements switch off automatically after 20 minutes. An acoustic signal will sound approximately 1 minute before the heating elements switch off automatically.
Press the button - A - at any time to reset the timer back to 20 minutes. An short acoustic signal confirms that it has be reset.
And further work is performed using the vehicle diagnostic tester in Guided Fault Finding.
- Turn on ignition.
- Touch the Guided Fault Finding button on the touch screen.
- Select the following one after the other:
• Brand
• Type
• Model year
• Version
• Engine Code
- Confirm the entered data.
Wait until the vehicle diagnostic tester has checked all the vehicle control module.
- Press the GO TO button and select "function/component selection".
- Select the program in "Guided Functions".
Follow the instructions on the screen of the vehicle diagnostic tester to perform the adjustment/calibration.
Turn the adjusting screw with a hex socket wrench (minimum length: approximately 120 mm) to mechanically adjust the infrared camera around its roller axle.
- Open the hood and remove the lock carrier cover - 1 -.
- Mount the hex socket wrench - 2 - and make the adjustment according to the specification in "Guided Fault Finding".
• Make sure there is no one or nothing between the infrared camera and the infrared system calibration plate while making the adjustment.
Adjusting the pitch-yaw angle of the infrared camera is electronic using vehicle diagnostic tester in "Guided Functions/Fault Finding."
