1. What is VCDS Error 02873 and How Do I Fix It?

VCDS Error 02873 typically indicates a problem with the control module for the back-up camera (J772), signaling a “No Signal/Communication” issue. The primary solution involves checking and replacing any faulty wiring or connectors. To delve deeper, reading Measuring Value Blocks (MVB) can provide additional insights.

1.1 Understanding the Root Cause of Error 02873

• Faulty Wiring: Damaged or corroded wiring can disrupt signal transmission.
• Connector Issues: Loose or damaged connectors can lead to communication failure.
• Module Malfunction: In rare cases, the control module itself may be defective.

1.2 Step-by-Step Solutions to Resolve VCDS Error 02873

1. Inspect Wiring and Connectors: Carefully examine all wiring and connectors associated with the back-up camera system. Look for signs of damage, corrosion, or loose connections.
2. Test Continuity: Use a multimeter to test the continuity of the wiring. Replace any damaged wires.
3. Check Connector Pins: Ensure that the connector pins are clean and properly seated. Clean them with an electronic cleaner if necessary.
4. Read Measuring Value Blocks (MVB): Use VCDS to read the Measuring Value Blocks (MVB). This can provide more specific information about the fault.
5. Replace Faulty Components: Replace any faulty wiring or connectors identified during the inspection.
6. Clear the Error Code: After addressing the issue, clear the error code using VCDS.
7. Test the System: Verify that the back-up camera system is functioning correctly after the repair.

2. Why is Back-Up Camera Calibration Important After Repairs?

Back-up camera calibration is crucial after performing any service work on the camera system to ensure accurate and reliable performance. Calibration is specifically needed after removing and installing the rear-view camera (R189), replacing the rear-view camera system control module (J772), or after any repair work performed on the rear lid following an accident. It is also necessary after a vehicle alignment or any repair work performed on the front or rear axle. Proper calibration ensures the camera provides accurate visuals, enhancing safety and convenience.

2.1 When is Back-Up Camera Calibration Required?

• Removing and Installing Rear View Camera (R189): The camera’s position may have been altered.
• Replacing Rear View Camera System Control Module (J772): The new module needs to be synced with the vehicle.
• After Rear Lid Repair: Bodywork can affect camera alignment.
• After Vehicle Alignment: Changes in vehicle geometry require recalibration.
• After Front or Rear Axle Repair: Adjustments can impact camera accuracy.

2.2 Prerequisites for Calibration

Before starting the calibration process, several conditions must be met to ensure accuracy.

• Calibration Device: A calibration device (VAS 6350) and distance laser (VAS 6350/2) are required, positioned as described in the factory repair manual.
• Vehicle Position: The vehicle must be standing on a firm and even surface.
• Stable Environment: Ensure no persons are being/working in/on the vehicle during calibration.
• Vehicle State: Do not move the vehicle or operate the doors while calibrating.
• Rear Lid Condition: The rear lid must be closed.
• Front Wheel Alignment: Front wheels should be straight, with the Steering Angle Sensor (G85) close to 0.0 °.
• Ignition and Power: The ignition must be ON, but the engine must NOT be running. Connect a charger to maintain system voltage.
• Camera Activation: The back-up camera must be active, and the MMI should display the back-up camera video signal.
• Lighting Conditions: Avoid light reflections on the Calibration Device (VAS 6350).
• Level Control: For vehicles with Level Control, set the height to automatic.

3. What is the Procedure for Back-Up Camera Calibration Using VCDS?

The calibration procedure involves several steps using VCDS (VAG-COM Diagnostic System) to ensure the back-up camera is correctly aligned. This process includes security access, adaptation channels, and saving new values based on precise measurements. Here’s a detailed guide:

3.1 Step-by-Step Calibration Process

1. Select Control Module:

   • Open VCDS and select [6C – Back-Up Camera].

2. Security Access:

   • Go to [Security Access – 16] and enter the code 22351 to enable adaptation.

3. Adaptation Channel 005:

   • Select [Adaptation – 10] and choose channel 005.
   • Click [Read]. The basis value is 500 mm.
   • Measure the height between the Calibration Device (VAS 6350) and the surface (e.g., 80 mm). Add this value to the basis value (500 mm + 80 mm = 580 mm).
   • Enter the final value as the new value and click [Test] [Save].

4. Adaptation Channel 004:

   • Select channel 004.
   • Click [Read]. The basis value is 20000 mm, and you need the wheelbase of the vehicle (e.g., 2855 mm for a 7L Touareg).
   • Measure the distance between the Calibration Device (VAS 6350) and the rear axle (e.g., 1500 mm).
   • Calculate the new value: 20000 mm – Wheelbase – Measured Distance (e.g., 20000 – 2855 – 1500 = 15645 mm).
   • Enter the final value as the new value and click [Test] [Save].

5. Adaptation Channel 001:

   • Select channel 001.
   • Click [Read].
   • Enter a new value of 1 to save the above adaptations and click [Test] [Save].

6. Final Steps:

   • Click [Done, Go Back].
   • Double-check the calibration status by going to [Measuring Value Blocks (MVB) – 08].
   • Select block 130 and click [Go!].
   • Check field 3 (Calibration Status). The specification should be 0x0000 (Calibration Successful).
   • Click [Done, Go Back] [Close Controller, Go Back – 06].

3.2 Vehicle-Specific Wheelbase Values

When calibrating, it’s crucial to use the correct wheelbase value for the specific vehicle model. Here are some common wheelbase values:

Vehicle Model	Wheelbase (mm)
VW Touareg (7L)	2855
VW Tiguan (5N)	2601
VW Passat (3C)	2709
VW Passat (35/CC)	2710
VW Passat (36)	2712
VW Sharan	2920
VW Phaeton (3D) Short	2881
VW Phaeton (3D) Long	3001
Bentley Continental GT	2745
Bentley Continental Flying Spur	3065

Note: The VW Touareg (7P) is NOT supported at this time.
