The BMW Scanner car diagnostic tool version 1.4.0 offers a powerful and affordable solution for diagnosing and customizing your BMW. This tool allows you to read and clear error messages, recode features, and gain a deeper understanding of your vehicle’s performance. While genuine BMW scanners can cost thousands of dollars, the 1.4.0 version provides a cost-effective alternative for enthusiasts and DIY mechanics.
Understanding the BMW Scanner 1.4.0’s Capabilities
This diagnostic tool empowers you to delve into your BMW’s computer system, providing access to a wealth of information. Its primary functions include:
- Reading and Erasing Error Messages: When your check engine light illuminates, the BMW Scanner 1.4.0 allows you to read the specific error messages stored in the car’s computer, not just generic codes. You can then clear these errors after addressing the underlying issue.
- Recoding Vehicle Features: Customize your BMW to your preferences by enabling or disabling various features. This includes options like one-touch window roll-up/down, disabling daytime running lights, adjusting door lock settings, and configuring the car for aftermarket modifications like HID headlights.
Preparing for Coding: Soldering and Software Installation
While the BMW Scanner 1.4.0 can read and clear errors out of the box, recoding features requires a simple soldering modification.
-
Soldering Pins 7 and 8: Open the scanner using a small Phillips head screwdriver and locate pins 7 and 8 on the circuit board. Solder these two pins together. This modification enables the coding functionality. Some versions may already have this connection soldered.
-
Software Installation: The scanner comes with a software disc compatible with Windows XP or older operating systems. Install the software and drivers according to the provided instructions. A virtual machine running Windows XP can be used on newer systems.
Using the BMW Scanner 1.4.0: Diagnostics and Coding
Once the software is installed and the scanner is connected to your car’s OBD port, you can begin diagnosing and coding.
-
Diagnostics: The software provides a comprehensive overview of your car’s systems. Select the “Scan” option to initiate a diagnostic scan. The scanner will identify any stored error messages, allowing you to pinpoint and address potential problems. Double-clicking on an error message will provide detailed information.
-
Coding: Access the coding functionality by double-clicking on specific modules within the software, such as the ZKE module for central locking and lighting. The coding interface allows you to enable or disable specific features. After making changes, click “Write” to apply the new settings.
Unlocking Your BMW’s Potential: Proceed with Caution
The BMW Scanner car diagnostic tool version 1.4.0 provides a gateway to personalize and maintain your BMW. However, it’s crucial to exercise caution when modifying your car’s settings. Thorough research and understanding of the potential impacts are essential. Incorrect coding can potentially lead to malfunctions or damage. While this guide provides a general overview, always consult reputable sources and forums for specific coding instructions and best practices.
