Rear Vision Camera: Testing and Inspection
Rearview Camera System, Calibrating
Special tools, testers and auxiliary items required
• Vehicle Diagnostic, Testing and Information System (VAS 5051B)
• Calibration Tool For Lane Changing Assist (VAS 6350)
• Spacing Laser (VAS 6350/2)
After performing service work on the vehicle, it may be necessary to calibrate the rear view camera system. In detail, this is the case after:
• Removing and installing Rear View Camera (R189)
• Replacing Rear View Camera System Control Module (J772)
• after repair work performed on rear lid following an accident
• after a vehicle alignment
• after performing a repair on the rear axle
Preparations Before Starting Work
Vehicle must stand on a firm and level surface to perform the calibration. No persons may be in the vehicle interior during the measurement. Vehicle must not be moved during the measurement, opening and closing of vehicle doors is to be avoided. The rear lid is closed.
- Connect the (VAS5051B).
- Bring the Steering Angle Sensor (G85) into 0-position (wheels straight ahead).

• For checking horizontal position of calibration platform
8 Left Angle Bracket
• (VAS 6350/2) mount
9 Measuring Field Of Calibration Platform
• Distance to rear wheel axle 1.47 m - 1.90 m - dimension A -.
Setting Up Measuring Device
Make sure light does not reflect off the calibration platform.
Reflections affect the rear view camera and may make it impossible to perform the calibration.
- Check which hole circle the rims have.
- Install the correct wheel pick-ups.
- To do so, secure three wheel bolt adapters in the hole circle to each wheel pick-up.
- Attach paddles to both wheel pick-ups and secure them with clamping screw.
- Set the wheel pick-ups onto wheel mounting bolts at the rear wheels.
When doing this, the wheel pick-ups are positioned by the O-rings in the adapters and held in place.
• Attach wheel pick-ups onto wheels so that any installed anti-theft wheel mounting bolts are not connected to the wheel pick-ups.
- Set the paddles via the clamping screw so that they are free to move just above the ground.
Make sure paddles move easily.
- Position calibration platform behind vehicle at a distance of 1.47 m -1.90 m from rear wheels, as depicted in overview - dimension A -.
- Bring calibration platform to a horizontal position.
The whole calibration board must be visible in the display when the rearview camera is on.
- Twist plastic feet under calibration platform so that air bubble in the level is located exactly in the center of the indicator - arrow -.
- Switch on laser - 1 - on calibration platform and align entire calibration platform so that laser beam hits center above of Audi rings.
- Make sure the Audi rings are centered on the rear. Adjust the laser beam as needed.
- Switch (VAS 6350/2) on with ON button.
The following display appears and laser is switched on.
- Hold (VAS 6350/2) - 2 - as shown in illustration on one side of calibration platform flush in bracket, the measuring devise must lie firmly on bracket when doing so.
- Make sure that laser beam from (VAS 6350/2) hits lower, enlarged part of paddle - 1 -.
If this is not the case, paddles must be corrected accordingly via clamping screws on the wheel pick-ups.
- With one hand, hold the (VAS 6350/2) firmly in the bracket on the calibration platform while the laser beam is visible on the paddle.
- Now press the ON button briefly for the distance measurement.
Display readout
- Note the value read off.
- Repeat measuring procedure in the same manner for the rear wheel on the other side of the calibration platform.
The distance value must be the same on both sides.
If values are not identical:
- Adjust calibration platform until values on both sides are identical.
When aligning the calibration platform, make sure the calibration platform laser beam still strikes the center of the rear window wiper and the indicator of the level remains centered. If necessary, make further corrections.
- Measure height of calibration platform, dimension - H - (top edge platform - floor).
The measured distance and height must now be entered in the (VAS 5051B) in millimeters.
Performing Calibration
In (VAS 5051B), select "Guided Functions".
or
In (VAS 5051B), select "Guided Fault Finding".
- Select the corresponding vehicle data in the "vehicle selection" menu.
- Select "rear view camera system".
- Select "functions".
- Select "Calibration".
Further assistance during calibration procedure is given by (VAS 5051B).
Make sure light does not reflect off the calibration platform.
Reflections affect the rear view camera and may make it impossible to perform the calibration.
