What is the Foxwell NT201 OBD2 Scanner?
The Foxwell NT201 is a handheld OBD2 (On-Board Diagnostics II) scanner. It’s engineered to read and clear engine fault codes in OBD2 compliant vehicles, which includes most cars and light trucks sold in the USA after 1996, European vehicles from 2000 onwards, and Asian cars from 2008 onwards. This scanner provides essential diagnostic functions in a compact and easy-to-use format. It’s aimed at individuals who want to understand their vehicle’s basic health and perform simple maintenance tasks themselves.
Key Features and Benefits of the NT201
The Foxwell NT201 packs several useful features into its small frame, making it a valuable tool for basic car diagnostics:
- Broad Vehicle Compatibility: Supports OBD2, EOBD, and JOBD protocols, ensuring it works with a wide range of vehicles globally.
- Read and Erase Engine Codes: Quickly identify the Diagnostic Trouble Codes (DTCs) causing the check engine light to illuminate and allows you to clear these codes after repairs.
- Live Data Stream: Monitors real-time vehicle operating conditions, providing insights into sensor data and system performance.
- Freeze Frame Data: Captures a snapshot of sensor values when a fault code is triggered, aiding in diagnosing intermittent issues.
- I/M Readiness: Checks the status of emission-related systems to ensure your vehicle is ready for smog tests.
- Vehicle Information (VIN): Retrieves essential vehicle details like VIN, CID, and CVN for accurate diagnostics and part identification.
- Color Display and Built-in Speaker: Features a 2.4-inch TFT color screen for clear data viewing and audible feedback.
- LED Indicator Lights: Includes green, yellow, and red LEDs to provide visual cues about the severity of detected issues at a glance.
Hands-on Experience: Testing the Foxwell NT201
Using the NT201 is straightforward. The package includes the scanner, a user manual, and a USB cable for updates. To test its functionality, the scanner was connected to a 2003 Volkswagen Passat with an active check engine light. The OBD2 port, typically located under the driver’s side dashboard, provides easy access for plugging in the device.
Upon connection, the NT201 quickly linked to the car’s computer system. Navigating to the OBDII options and selecting “Read Codes” revealed two error codes. The red LED indicator on the scanner also illuminated, signaling a problem. The scanner displayed the code “P2181,” indicating a “Cooling System Performance” issue.
The “Erase Codes” function was then used, which successfully turned off the check engine light on the dashboard. While the code was cleared, it’s important to note that this action doesn’t fix the underlying problem, which in this case is the cooling system. The scanner effectively performed its function of reading and clearing codes, allowing for a basic understanding of the issue and the ability to clear the light after addressing the problem.
Beyond basic code reading and clearing, the NT201 offers access to live data, freeze frame information, and I/M readiness status. These features provide more in-depth diagnostic capabilities for users who want to delve deeper into their vehicle’s performance.
