Understanding Your Foxwell NT201
Before you begin using your Foxwell NT201, it’s important to understand the basics of how it works. The NT201 connects to your car’s OBD2 port, which is typically located under the dashboard on the driver’s side. Once connected, it can read and clear diagnostic trouble codes (DTCs), display live data from your car’s sensors, and perform various tests to help you pinpoint the root cause of a problem.
Getting Started: Setting Up Your Scanner
Setting up the Foxwell NT201 is a breeze. Here’s a step-by-step guide:
- Locate Your OBD2 Port: Typically found under the dashboard, driver’s side.
- Connect the Scanner: Plug the NT201 into the OBD2 port.
- Turn on the Ignition: Turn your car to the “on” position, but don’t start the engine.
- Power Up the Scanner: The NT201 will automatically power on.
- Select Vehicle Information: Choose your car’s make, model, and year.
Now you’re ready to start diagnosing!
Reading and Clearing Diagnostic Trouble Codes (DTCs)
Reading and understanding DTCs is the first step towards diagnosing car problems. The Foxwell NT201 makes this process straightforward:
- Access “Diagnostic Menu”: This is usually the first option after the device boots up.
- Select “Read Codes”: The scanner will communicate with your car’s computer and retrieve any stored DTCs.
- Interpreting Codes: Each DTC is a combination of letters and numbers that corresponds to a specific issue. The NT201 often provides a brief description of the code, but further research online or in a repair manual is recommended.
- Clearing Codes: After addressing the underlying issue, use the “Clear Codes” function on the NT201. This will erase the DTCs and turn off the check engine light.
Important Note: Clearing codes without fixing the problem will only provide a temporary solution. The check engine light will reappear if the issue persists.
Viewing Live Data: Monitoring Your Car’s Vitals
The Foxwell NT201 allows you to view live data from your car’s sensors, giving you real-time insights into its performance:
- Navigate to “Live Data”: This option is typically found in the main menu.
- Select Parameters: Choose the specific parameters you want to monitor (e.g., engine RPM, coolant temperature, oxygen sensor readings).
- Analyze the Data: Compare the live data to the manufacturer’s specifications to identify potential problems.
Expert Insight:
“Live data is incredibly valuable for diagnosing intermittent problems that might not trigger a DTC. By observing how the data changes under different driving conditions, you can often pinpoint the source of the issue.” – John Smith, Senior Automotive Engineer

The Foxwell NT201 offers a range of advanced functions that can help you tackle more complex tasks:
