BPPS Relearn Scan Tool: A Comprehensive Guide Using VX Nano

Performing a Brake Pedal Position Sensor (BPPS) relearn is a common procedure in modern vehicle maintenance, often required after replacing the sensor or performing certain repairs. For automotive technicians and DIY enthusiasts, having the right scan tool is crucial for efficiently completing this task. The VX Nano stands out as a versatile and cost-effective option, functioning as an excellent Bpps Relearn Scan Tool. This guide provides a step-by-step walkthrough on how to use the VX Nano for BPPS relearn, ensuring a smooth and successful process.

Software Installation and Setup

Before you can utilize the VX Nano as your bpps relearn scan tool, you need to install the necessary software on your Windows PC. Follow these steps carefully:

1. VX Manager Installation: Begin by installing VX Manager version 1.8.4 on a computer running Windows 7 or a later version. During the installation, Windows Defender might flag VX Manager as potentially problematic. This is a common occurrence. If a pop-up from Defender appears, you need to click on it and allow VX Manager to proceed with the installation. This step is crucial for the VX Nano to function correctly.

2. VX Nano Firmware and License Update: Once VX Manager is successfully installed and running, connect your VX Nano device to your computer via USB. Within VX Manager, locate and click on the “Firmware” icon to initiate a firmware update for the Nano. After the firmware update is complete, click on the “License” icon to update the device’s license. Keeping both firmware and license updated ensures optimal performance and access to the latest features.

3. Tech2Win Installation: With VX Manager open and the VX Nano still connected, proceed to install Tech2Win. This software is typically included on a disc that comes with the VX Nano, usually found in a folder labeled “tech2 win”. Run the “Tech2autoinstall.exe” file from this folder. This installation will place two Tech2Win icons on your desktop. Identify the icon labeled “Quickstart” and delete it, as it is not needed for standard operation and can be confusing.

4. Install Diagnostic Applications in VX Manager: Return to the VX Manager interface. Click on the “Diagnostic” tab located at the top. Then, on the left-hand side menu, select the second tab from the top. Within this section, install the following applications: “Passthru,” “GM GDS2/T2W,” and “RDS SGM.” These applications are essential for the VX Nano to communicate with your vehicle and perform diagnostic functions, including BPPS relearn. After installing these applications, restart your computer to ensure all software components are properly configured and initialized.

Using VX Nano for BPPS Relearn

With the software installation complete, you are now ready to use the VX Nano as a bpps relearn scan tool. Follow these steps to perform a BPPS relearn procedure:

1. Launch Tech2Win and Configure Connection: Ensure the VX Nano is plugged into your computer. Start the Tech2Win application by clicking on the Tech2Win icon on your desktop. You will be presented with a series of pop-up screens to configure the connection.

   • On the first pop-up, select “North America.”
   • On the second pop-up, choose “MDI 1.”
   • On the third pop-up, select “USB device” from the list. This configures Tech2Win to communicate with the VX Nano via the USB connection. You should now be in the main Tech2Win program interface.

2. Vehicle Connection and Module Selection:

   • Turn your vehicle’s ignition to the ACC (Accessory) mode.
   • Connect the VX Nano device to the OBDII port in your vehicle.
   • In the Tech2Win software on your laptop, click “OK.”
   • Select “F0: Diagnostics.”
   • Choose the vehicle year. Important Note: For vehicles manufactured in 2006 or later, you need to select “2013” to access the BCM (Body Control Module). This is a known software quirk. For accessing other modules, use the actual year of your vehicle.
   • Select “Passenger Car,” then “Chevy,” and your vehicle’s body type (e.g., “Y body type”).
   • Choose “Body” from the module selections. Allow the program to read the vehicle information.
   • From the body module menu, locate and select “BPS Relearn.” This will initiate the Brake Pedal Position Sensor relearn procedure.

3. Performing the BPPS Relearn Procedure: Tech2Win will guide you through the BPPS relearn steps. Pay close attention to the on-screen instructions. Typically, the procedure involves two parts:

   • Part 1 (Pedal at Rest): The instructions will likely prompt you to keep the brake pedal at rest. Do not press the brake pedal during this initial phase.
   • Part 2 (Pedal Press): When instructed, press the brake pedal. It’s important to apply gentle and consistent pressure. Avoid pressing the pedal forcefully (“buck wild”). Press it just enough to engage the brakes lightly. Follow the on-screen prompts to complete the relearn process.

4. Clutch Position Sensor (CPS) Relearn (If Applicable): If you need to perform a Clutch Position Sensor relearn instead of BPPS relearn, the process is similar. In the body module menu, select “CPS Relearn.” The procedure for CPS relearn also involves two parts:

   • Part 1 (Pedal at Rest): Start with the clutch pedal at rest (not pressed).
   • Part 2 (Pedal Fully Depressed): When prompted, fully depress the clutch pedal and hold it down. Follow the on-screen instructions to complete the CPS relearn.

VX Nano: More Than Just a BPPS Relearn Scan Tool

The VX Nano is not limited to just BPPS relearn procedures. It is a versatile diagnostic interface that offers capabilities beyond basic scan tools. As an MDI (Multiple Diagnostic Interface) clone, the VX Nano can function as:

• Tech 2 Emulator: It effectively emulates a Tech 2 scan tool when running Tech2Win software, allowing you to perform in-depth diagnostics and programming on older vehicles.
• MDI Interface for GDS2: The VX Nano also operates as a genuine MDI interface for newer vehicles, compatible with GDS2 (Global Diagnostic System 2) software used for diagnostics on newer GM models.
• Module Programming: It supports TIS2000 for module firmware flashing on vehicles up to 2009 and TDS (Techline Data Subscription) for firmware flashing on vehicles from 2010 onwards.

In conclusion, the VX Nano is a powerful and affordable bpps relearn scan tool that offers a wide range of diagnostic and programming capabilities. By following this guide, you can effectively use the VX Nano for BPPS relearn and explore its other functionalities for comprehensive vehicle maintenance and repair.
