FOXWELL NT301 Plus 2-in-1 OBD2 Scanner & Battery Tester | Engine & Battery Diagnostics for 1996+ Vehicles

Meet the FOXWELL NT301 Plus: 2-in-1 Engine and Battery Diagnostics

The FOXWELL NT301 Plus refines the classic NT301 into a compact, two-in-one diagnostic companion for DIYers and car owners. Beyond engine fault codes, it evaluates battery health, offering a clearer, more comprehensive view of your vehicle’s condition without a trip to the shop. Its 2.8-inch color display is larger and brighter, making results easier to read at a glance, even in a dim garage or bright sun.

Key advantages at a glance

• 2-in-1 engine and battery diagnostics save you time and effort.
• 36% larger 2.8-inch color display for easier interpretation of results.
• Read and clear check engine lights with a built-in DTC library that provides plain English meanings.
• Battery health metrics such as SOH, SOC, CCA, and cranking performance help you plan maintenance.
• Emissions checks including I/M readiness and EVAP leak testing for inspection preparation.

In everyday use

Use the NT301 Plus after a short drive to confirm engine readiness, or during routine maintenance to monitor battery health. It records live data like RPM, coolant temperature, and fuel trim, enabling you to spot intermittent issues over time. You can save diagnostic data and print reports for your files or to share with a repair shop. This makes it a practical choice for home workshops and on-the-road troubleshooting alike.

Real-world scenarios include a check engine light that needs quick interpretation, a battery that may be weak before a long trip, or a need to verify emissions readiness ahead of a drive test. The tool aims to provide clear, actionable information and encourage careful, informed decisions about next steps.

Compatibility and important notes

The NT301 Plus supports 1996+ US vehicles, 2001+ European models, and 2005+ Asian cars via the standard 16-pin OBDII port. While it covers a broad range of makes and models, some vehicles may require extra connectors or have limited support. It is designed for engine and 12-volt battery diagnostics only and does not include ABS, SRS, or key programming features. Windows-only updates are provided; please confirm compatibility with your device before updating.
