Imagine you’re a mechanic, and a customer’s car is experiencing a strange electrical issue. You’ve tried everything, but you can’t pinpoint the problem. Frustrated, you’re left with only one option: to connect a scan tool to the car’s OBDII port and hope for the best.
In today’s digital world, scan tools have become an essential diagnostic tool for any mechanic. These tools can read and interpret data from a car’s engine control unit (ECU) and provide valuable information that can help diagnose problems. But not all scan tools are created equal. For European cars, you need a scan tool that supports CAN (Controller Area Network) communication.
Understanding OBDII Scan Tools w CAN
OBDII (On-Board Diagnostics II) is a standardized diagnostic system found in most vehicles manufactured after 1996. It allows technicians to access and interpret data from the car’s ECU through a diagnostic connector, often located under the driver’s side dashboard.
CAN (Controller Area Network) is a communication protocol used in modern vehicles to connect different electronic control units (ECUs). These ECUs are responsible for everything from engine management to transmission control and even climate control.
Scan tools with CAN capability can access and interpret data from all the ECUs connected via CAN bus. This is essential for diagnosing problems with European vehicles, which often rely heavily on CAN communication.
Why You Need a Scan Tool with CAN for European Cars
Most European cars manufactured after 2000 utilize a CAN network. These vehicles often have advanced electronic systems, such as:
- Electronic Stability Control (ESC): This system helps prevent the vehicle from skidding or losing control.
- Anti-lock Braking System (ABS): This system prevents the wheels from locking up during braking.
- Airbag System: This system deploys airbags in case of an accident.
- Advanced Engine Management Systems: European cars are known for their advanced engines, which rely heavily on electronic controls.
These systems are interconnected through the CAN bus, and diagnosing problems with one system can often require accessing data from other ECUs. A scan tool without CAN capability may be able to read data from the ECU, but it won’t be able to access and interpret data from other ECUs connected via CAN.
What To Look For in an OBDII Scan Tool w CAN
When choosing a scan tool for European cars, there are several key features to consider:
- CAN Compatibility: The scan tool must support CAN communication to access data from all ECUs connected via CAN bus.
- Vehicle Coverage: Make sure the scan tool is compatible with your specific car make and model.
- Diagnostic Capabilities: The scan tool should be able to read and clear fault codes, view live data, and perform other diagnostic functions.
- Ease of Use: The scan tool should be user-friendly and intuitive to operate.
- Price: Scan tools can range in price from a few hundred dollars to several thousand dollars. Consider your budget and the features that are most important to you.
The Power of a Scan Tool with CAN
Imagine this: You’re trying to diagnose a problem with a BMW 5 Series. The car is experiencing erratic acceleration and a flashing engine light. Using a basic OBDII scan tool, you can read the fault code, but it only provides limited information.
By connecting a scan tool with CAN capability, you can access data from the ECU responsible for the engine management system. You can also view live data, such as engine speed, throttle position, and air/fuel ratio. This information can help you identify the root cause of the problem and troubleshoot it more effectively.
Finding the Right Scan Tool for Your Needs
The best scan tool for your needs will depend on your budget, the types of vehicles you work on, and the features you require.

Frequently Asked Questions About OBDII Scan Tools w CAN
Q: Can I use a basic OBDII scan tool on a European car?
A: While a basic OBDII scan tool may be able to read some data from the ECU, it may not be able to access and interpret data from all ECUs, especially those connected via CAN bus. For European vehicles, a scan tool with CAN capability is essential for thorough diagnostics.
Q: What are some of the benefits of using a scan tool with CAN?
A: A scan tool with CAN offers numerous benefits, including:
- Access to more data: It can read and interpret data from all ECUs connected via CAN bus, providing a more comprehensive view of the vehicle’s systems.
- More accurate diagnostics: By accessing data from multiple ECUs, it can help pinpoint the root cause of a problem more effectively.
- Faster troubleshooting: It can help reduce the time and effort required to diagnose and repair problems.
Q: How do I choose the right scan tool with CAN for my needs?
A: Consider your budget, the types of vehicles you work on, and the features you require. Look for a scan tool that is compatible with CAN communication, covers your specific vehicle make and model, and offers the diagnostic capabilities you need.
Q: Where can I buy a scan tool with CAN?
A: You can purchase a scan tool with CAN from several sources, including online retailers, automotive supply stores, and professional tool distributors.
Final Thoughts: Embrace the Power of Diagnostics
Investing in a scan tool with CAN capability is an investment in your success as an automotive technician. It empowers you to diagnose problems more effectively, reduce repair time, and increase customer satisfaction.
If you’re working on European vehicles, a CAN-enabled scan tool is a must-have. It provides a level of diagnostic power and insight that you can’t get with a basic OBDII scan tool.
