You’re working on a European car, the engine light is on, and you need to diagnose the problem. You pull out your trusty scan tool, ready to delve into the car’s electronic network. But what if your scan tool isn’t compatible with the car’s system? This is where a network scanning tool, often referred to as a “Jaws” tool, comes in.
What is a Network Scanning Tool?
A network scanning tool, also known as a “Jaws” tool due to its distinctive appearance, is a specialized diagnostic device used to access and analyze the electronic network of modern vehicles. It allows technicians to “talk” to the various electronic control units (ECUs) within the vehicle, including the engine control unit (ECU), transmission control unit (TCU), and airbag control unit (ACU). Think of it as a translator for the vehicle’s complex electronic language.
Why are Network Scanning Tools Important?
These tools are essential for diagnosing a wide range of issues in modern vehicles, especially those with sophisticated electronic systems. Here’s why:
- Accessing Data: Network scanning tools can retrieve data from all ECUs in the car, providing valuable insights into the vehicle’s operation. This data can be used to identify malfunctioning sensors, faulty wiring, and other problems that might not be obvious through conventional diagnostic methods.
- Reprogramming ECUs: Network scanning tools allow technicians to reprogram ECUs, which is essential for tasks like updating software, calibrating components, and restoring factory settings.
- Troubleshooting Electrical Problems: Network scanning tools can pinpoint the source of electrical issues by analyzing communication between ECUs. This can help diagnose problems with wiring harnesses, connectors, and even faulty components.
Understanding the “Jaws”
The term “Jaws” is often used to describe a specific type of network scanning tool that connects to the car’s network via a diagnostic connector, typically located under the dashboard. These tools are named for their distinctive design, which resembles a pair of jaws that clamp onto the connector. This connection provides a secure and stable connection, allowing the tool to communicate with the vehicle’s ECUs effectively.

Network Scanning Tools for European Cars
Many network scanning tools are designed specifically for European cars. These tools often feature advanced capabilities, such as support for multiple protocols and languages, allowing them to communicate with a wider range of vehicle brands and models. Some popular examples include:
- Autologic: This network scanning tool is known for its comprehensive coverage of BMW and other European brands. It’s a popular choice among professional technicians and enthusiasts alike.
- Dealer Level Scanner: These tools provide access to the same diagnostic information and functionalities that are available to authorized dealerships. They offer an excellent level of detail and can be used to diagnose complex issues.
- OEM-Specific Scanners: Some manufacturers offer their own dedicated scanners for their vehicles, such as the Audi VAS 5054A and the Mercedes Star Diagnosis. While these tools are often expensive, they provide the most comprehensive coverage and access to specialized features for their respective brands.
How to Choose the Right Network Scanning Tool
Choosing the right network scanning tool for your needs depends on your level of experience, the specific car you’re working on, and your budget. Here are some key factors to consider:
- Vehicle Compatibility: Ensure the tool is compatible with your vehicle’s make, model, and year. Check the manufacturer’s website for compatibility information.
- Functionality: Consider the features and functionalities you need, such as live data streaming, code reading, ECU reprogramming, and network analysis.
- Ease of Use: Choose a tool with a user-friendly interface that is easy to navigate and understand.
- Price: Network scanning tools can range in price from a few hundred dollars to several thousand dollars. Set a budget and research different options to find the best value for your money.
