vLinker vLinker FD+ Bluetooth OBD2 Scanner - High‑Speed OBDII Adapter for iOS Android Windows, Bi‑Directional Tests

Built for home mechanics, technicians, and enthusiasts who need fast, reliable access to onboard diagnostics, the vLinker FD+ combines robust data throughput, manufacturer-level network access, and safety features that let you leave it connected. It supports both classic ELM command sets and extended For-d specific networks, works with popular third-party apps, and includes automatic power-protection to preserve vehicle batteries. Use it with iOS, Android, or Windows devices to read and clear codes, monitor live sensor values, log trips, and run active tests when the connected app supports bi-directional commands.

How does vLinker FD+ improve everyday troubleshooting?

vLinker FD+ processes larger diagnostic frames and higher baud rates than many basic adapters, so it retrieves extended data and lengthy messages faster and more reliably. Faster responses reduce wait times during live-data streaming and make app features like trip computer and logging smoother. For DIYers this means quicker fault isolation; for shops it improves throughput.

• High baud rate up to 230.4 Kbps for faster live data.
• Large USART buffer and support for long OBD request frames.
• Works with apps that show real-time graphs and historic logs.

Can it perform active tests and control vehicle modules?

The FD+ supports bi-directional control through compatible apps, allowing you to send commands to the ECU for active testing and function checks. This capability helps narrow down fault locations without disassembly, but functionality depends on the app, vehicle make, model year, and available ECU commands. Always consult your app documentation for supported tests.

• Bi-directional control when used with apps that implement ACT tests.
• Dependent on vehicle manufacturer and app feature set.
• Useful for valve, relay, and actuator checks when supported.

Will leaving it plugged in harm my car battery?

vLinker FD+ includes power-safeguard features like auto-sleep/wake and protections against over-voltage, over-current, and overheating. The adapter operates at a very low idle current and can enter deep sleep to avoid draining the battery, so it’s safe for extended connection during diagnostics or monitoring. However, extreme conditions and older batteries should still be monitored.

• Auto sleep with idle current as low as 3 mA.
• Protection circuitry for voltage, current, and temperature.
• Multiple wake-up methods for convenience during use.

Which vehicles and apps are compatible with FD+?

The FD+ supports all standard OBD-II protocols and includes HS-CAN/MS-CAN access used on many For-d networks, letting it reach both generic and some manufacturer-specific modules. It follows ELM/STN command sets so it works with a wide ecosystem of apps on iOS, Android, and Windows. Note: 24V heavy-duty diesel systems are not supported.

• Works with 1996 and newer 12V petrol and most small diesel vehicles (under 6.5T).
• Compatible with Torque, OBD Fusion, DashCommand, FORScan, BimmerCode, and more.
• Recommended for FORScan users and compatible with ELM327/ELM329 command sets.

Who is this for? vLinker FD+ is aimed at car owners who want more than a basic code reader: DIY technicians, mobile mechanics, hobbyists, and repair shops that require deeper network access, faster live-data, and the option for active ECU testing through third-party apps. It’s also useful for travelers and fleet users who need a compact, durable adapter with battery protection and lifetime firmware updates. If you rely on your smartphone or laptop for vehicle diagnostics and want broader protocol coverage plus safety features, the FD+ is designed to meet those needs.
