FOXWELL NT301 OBD2 Scanner with Live Data

This compact OBD2 scanner from FOXWELL helps identify engine faults and view live vehicle data for quicker troubleshooting, whether you work in a garage or handle regular maintenance at home. It combines basic code reading with battery and alternator testing to give a clearer picture of a vehicle’s starting and charging systems.

Key Points

The tool reads and clears diagnostic trouble codes and shows live data streams for engine parameters, making it useful during road tests and shop checks. It supports a wide range of light vehicles, SUVs and vans sold worldwide and includes specific battery testing functions that report cold cranking amps and state of health. The interface is straightforward and aimed at mechanics and DIY users who want fast access to check engine light information and basic electrical system checks. Note that advanced manufacturer-specific functions may not be available on all models.

Technical Specifications

• Name: FOXWELL NT301 OBD2 Scanner
• Supported vehicles: Light cars, light trucks, SUVs and vans sold worldwide
• Battery test range: 100-2000 CCA (measures 12 V and 24 V systems)
• Battery rating compatibility: CCA, BCI, CA, MCA, JIS, DIN, IEC, EN, SAE, GB
• Functions: Read/erase codes, live data display, battery condition, alternator voltage check

Benefits

This scanner gives a quick overview of battery health by calculating actual cold starting capacity and estimating battery aging. It also measures alternator output voltage so you can detect charging faults without needing separate tools. The live data capability lets you monitor RPM, fuel trim and sensor readings in real time, which speeds up diagnosis during test drives. According to the manufacturer, the broader CCA measurement range is designed to cover common 12 V and 24 V vehicle batteries.

Usage Recommendations

Connect the OBD2 connector to the vehicle port and turn the ignition to the on position to begin scanning. For battery tests perform a static measurement with the engine off and then check alternator voltage with the engine running to compare readings. Keep in mind that while this model covers many global vehicle makes, some late-model cars may restrict access to certain systems or require manufacturer-specific tools for full diagnostics.
