How to Enable ARBC PGM LMC Using an OBD Scanner for Volkswagen

Volkswagen vehicles are known for their advanced technology and features, but some of these features may not be enabled by default. One such feature is the Adaptive Rear Blind Spot Control (ARBC) with Predictive Guidance Module (PGM) and Lane Marking Control (LMC). This blog post will guide you through the process of enabling this feature using an OBD scanner, specifically for Volkswagen vehicles.

Understanding ARBC PGM LMC

Before we dive into the enabling process, let's break down what ARBC PGM LMC means:

ARBC (Adaptive Rear Blind Spot Control): This system helps detect vehicles in your blind spots and alerts you when changing lanes.
PGM (Predictive Guidance Module): This module uses data from various sensors to predict potential hazards and adjust the vehicle's systems accordingly.
LMC (Lane Marking Control): This feature helps keep the vehicle within lane markings, enhancing overall driving safety.

Combined, these features significantly improve the safety and driving experience of your Volkswagen vehicle.

Why Use an OBD Scanner?

An OBD (On-Board Diagnostics) scanner is a powerful tool that allows you to access your vehicle's computer system. For Volkswagen owners, using an OBD scanner offers several advantages:

Access to advanced vehicle diagnostics
Ability to customize various vehicle settings
Cost-effective alternative to dealer visits for minor adjustments
Real-time monitoring of vehicle performance

By using an OBD scanner, you can enable features like ARBC PGM LMC without the need for a costly visit to a Volkswagen dealership.

Choosing the Right OBD Scanner

Not all OBD scanners are created equal. For enabling ARBC PGM LMC on your Volkswagen, you'll need a scanner that's compatible with VW's systems. Here are some recommended options:

VCDS (VAG-COM Diagnostic System): This is a popular choice among VW enthusiasts, known for its comprehensive functionality.
OBDeleven: A user-friendly option that works with a smartphone app, offering both basic and advanced coding options.
Ross-Tech HEX-V2: A professional-grade scanner that provides in-depth access to VW systems.

Whichever scanner you choose, ensure it's compatible with your specific Volkswagen model and year.

Preparing for the Enabling Process

Before you start enabling ARBC PGM LMC, there are a few important steps to take:

Ensure your vehicle's battery is fully charged. The coding process can drain the battery, and an interruption could lead to issues.
Park your vehicle in a safe, level area away from traffic.
Familiarize yourself with your chosen OBD scanner and its software.
Check for any existing error codes in your vehicle's system and address them before proceeding.

Locating the OBD Port

The OBD port in most Volkswagen vehicles is located under the dashboard on the driver's side. Here's how to find it:

Sit in the driver's seat and look under the dashboard.
The OBD port is typically near the steering column, often behind a small cover.
The port has a trapezoidal shape with 16 pins.

If you're having trouble locating the port, consult your vehicle's manual for the exact location.

Connecting the OBD Scanner

Once you've located the OBD port, follow these steps to connect your scanner:

Ensure the ignition is off.
Plug the OBD scanner into the port. The connector should fit snugly.
Turn the ignition to the "ON" position, but don't start the engine.
Wait for the scanner to power up and establish a connection with your vehicle's systems.

Most modern OBD scanners will automatically detect your vehicle model and year.

Accessing the ARBC PGM LMC Function

The exact steps to access the ARBC PGM LMC function may vary depending on your OBD scanner. However, the general process is as follows:

From the main menu, navigate to "Control Modules" or "Vehicle Systems."
Look for "Driver Assistance Systems" or "Adaptive Cruise Control."
Within this module, search for options related to "Rear Assist" or "Blind Spot Detection."
You may need to access "Long Coding" or "Adaptation" within these menus.

If you're using OBDeleven, you might find a one-click app for enabling this feature, simplifying the process significantly.

Enabling ARBC PGM LMC

Once you've located the correct menu, follow these steps to enable ARBC PGM LMC:

Look for options like "ARBC," "PGM," or "LMC" in the coding or adaptation menus.
Change the value from "Not Activated" to "Activated" or from "0" to "1," depending on your scanner's interface.
Save the changes and exit the menu.
The scanner may prompt you to cycle the ignition. Follow the on-screen instructions.

After enabling the feature, it's crucial to perform a system scan to ensure no errors were introduced during the coding process.

Verifying the Activation

To confirm that ARBC PGM LMC has been successfully enabled:

Start your vehicle and check for any new warning lights on the dashboard.
Test the blind spot detection system by having someone walk behind your vehicle while in reverse.
Take a short drive to ensure the lane marking control is functioning correctly.

If you encounter any issues or warning lights, use your OBD scanner to check for error codes and address them accordingly.

Potential Challenges and Solutions

While enabling ARBC PGM LMC is generally straightforward, you might encounter some challenges:

Challenge	Solution
Scanner not connecting	Check cable connections and ensure your scanner's firmware is up to date
Feature not available in menus	Verify your vehicle is compatible with ARBC PGM LMC
Errors after activation	Perform a full system scan and clear any new error codes

Legal and Warranty Considerations

Before enabling ARBC PGM LMC, consider the following:

Modifying your vehicle's software may void parts of your warranty. Check with your dealer for specifics.
Ensure that enabling this feature complies with local traffic laws and regulations.
Some insurance policies may be affected by vehicle modifications. Consult your insurance provider if unsure.

Maintaining Your Enabled ARBC PGM LMC System

Once you've successfully enabled ARBC PGM LMC, proper maintenance is crucial:

Regularly clean the sensors and cameras associated with the system.
Perform periodic system checks using your OBD scanner to ensure everything is functioning correctly.
Keep your vehicle's software up to date by visiting your Volkswagen dealer for any available updates.
If you experience any issues with the system, address them promptly to ensure continued safe operation.

Advanced Features and Customization

For enthusiasts looking to further customize their ARBC PGM LMC system, some OBD scanners offer advanced options:

Adjusting the sensitivity of blind spot detection
Customizing alert tones or visual indicators
