How to Write in ARBC PGM Dummy Mode with an OBD Scanner for Volkswagen Rear View Camera Systems

As automotive technology continues to advance, more vehicle owners are looking to enhance their driving experience with aftermarket upgrades. One popular modification for Volkswagen owners is the installation of a rear view camera system. However, to properly integrate this feature, you may need to access and modify certain vehicle settings using an OBD (On-Board Diagnostics) scanner. In this comprehensive guide, we'll explore how to write in ARBC PGM Dummy Mode using an OBD scanner for Volkswagen vehicles, with a focus on rear view camera systems.

Understanding ARBC PGM Dummy Mode

ARBC PGM Dummy Mode refers to a specific programming mode used in Volkswagen vehicles to enable or modify certain features, including rear view camera functionality. This mode allows technicians and knowledgeable owners to make changes to the vehicle's electronic systems that aren't typically accessible through standard interfaces.

Saves time and money compared to dealer programming

Choosing the Right OBD Scanner

To successfully write in ARBC PGM Dummy Mode, you'll need a compatible OBD scanner. Not all scanners have the capability to access this mode, so it's crucial to select the right tool.

Recommended OBD Scanners for Volkswagen

Scanner Model	Compatibility	Key Features
VCDS (VAG-COM Diagnostic System)	Most VW/Audi vehicles	Comprehensive coding capabilities, frequent updates
OBDeleven	VW Group vehicles	User-friendly interface, mobile app integration
ANCEL VD500	VW, Audi, Skoda, Seat	Affordable, supports basic and advanced functions

The ANCEL VD500 is a particularly good option for those new to OBD scanning. It's designed specifically for Volkswagen Group vehicles and supports both basic and advanced diagnostic functions.

Preparing Your Vehicle for ARBC PGM Dummy Mode

Before attempting to write in ARBC PGM Dummy Mode, ensure your vehicle is properly prepared:

Park your Volkswagen in a safe, level area
Ensure the battery is fully charged or connect a battery maintainer
Turn off all electrical systems (lights, radio, climate control)
Have your vehicle's manual and OBD scanner instructions nearby
Familiarize yourself with your specific Volkswagen model's electrical system

Step-by-Step Guide to Accessing ARBC PGM Dummy Mode

Now that you're prepared, let's walk through the process of accessing ARBC PGM Dummy Mode using an OBD scanner:

1. Connect the OBD Scanner

Locate your vehicle's OBD-II port, typically found under the dashboard on the driver's side. Plug in your OBD scanner and turn on the vehicle's ignition (but don't start the engine).

2. Navigate to the Appropriate Module

Using your OBD scanner's interface, navigate to the module responsible for the rear view camera system. This is often found under "Module 5F - Information Electronics" or "Module 56 - Radio".

3. Enter Long Coding

Once you've accessed the correct module, look for an option called "Long Coding" or "Adaptation". This is where you'll be able to make changes to enable or modify the rear view camera functionality.

4. Locate ARBC PGM Dummy Mode

Within the Long Coding menu, search for settings related to "ARBC", "PGM", or "Rear View Camera". The exact terminology may vary depending on your vehicle model and OBD scanner.

5. Modify Settings

Once you've found the relevant settings, you can modify them to enable or customize the rear view camera function. Common modifications include:

Activating the rear view camera input
Setting camera display guidelines
Adjusting camera activation speed
Configuring automatic activation when in reverse

6. Save Changes and Exit

After making the desired modifications, save your changes and exit the coding menu. Some scanners may require you to "commit" the changes before they take effect.

7. Test the Rear View Camera

With the changes saved, test your rear view camera system to ensure it's functioning as expected. Put the vehicle in reverse and check if the camera display appears on your infotainment screen.

Specific Coding for Volkswagen Models

Different Volkswagen models may require slightly different coding procedures. Here are some model-specific instructions:

For Volkswagen Golf MK7 with MIB2 Infotainment:

To activate the rear view camera (RVC Low) option, use the following coding:


Module 5F → Long Coding →Byte: 19 → Bit: 4 (RVC Low) → active
Module 76 → Long Coding →Byte: 02 → Bit: 4 (RVC installed)→ active

For Volkswagen Passat with RNS315 Navigation:

The rear view camera activation process may require an additional step:

Perform the coding as described above
Turn off the ignition and remove the key
Open and close all doors, then lock the car
Wait for 3 minutes to allow the car to enter sleep mode
Start the car and test the rear view camera

Troubleshooting Common Issues

If you encounter problems while writing in ARBC PGM Dummy Mode or with your rear view camera system, try these troubleshooting steps:

Double-check all connections, including the camera wiring and OBD scanner
Verify that you've selected the correct module and coding options
Ensure your OBD scanner's software is up to date
Clear any existing error codes before making changes
If changes don't take effect, try disconnecting the battery for a few minutes to reset the system

Safety Considerations and Best Practices

When working with vehicle electronics and OBD scanners, it's crucial to prioritize safety and follow best practices:

Always refer to your vehicle's manual and OBD scanner instructions
Make a backup of your current settings before making changes
Avoid making multiple changes at once – test each modification individually
Never perform coding while the vehicle is in motion
If you're unsure about any step, consult a professional technician

Legal and Warranty Implications

Before modifying your Volkswagen's systems, be aware of potential legal and warranty implications:

Some modifications may void parts of your vehicle's warranty
Ensure any aftermarket camera installations comply with local traffic laws
Be prepared to return the vehicle to its original state if required for service
