vLinker iCar2 Bluetooth OBD2 Diagnostic Scanner (Black) — Live Data, Read & Clear Codes

vLinker iCar2 is a compact Bluetooth OBD2 adapter that turns your iPhone, Android, or Windows device into a professional-level diagnostic scanner for reading and clearing fault codes, monitoring live data, and performing basic system tests.

Built for DIYers, mobile mechanics and road travelers, the vLinker iCar2 BLE4.0 plugs into any OBD2-compliant 12V vehicle and streams ECU information wirelessly to popular third-party apps. Lightweight and energy-efficient, it supports fault code reading and clearing, live sensor feeds, freeze frame data, battery health checks and selective subsystem checks (ABS, airbags, tire pressure where supported by vehicle). The adapter includes battery-protection features so it can remain connected without draining the car battery.

How do I use the vLinker iCar2 to read and clear engine codes?

After plugging the adapter into your vehicle’s OBD2 port, pair it with your device over Bluetooth and open a compatible app (apps not included). Once connected you can read stored and pending Diagnostic Trouble Codes (DTCs), view code descriptions inside many apps, and clear check engine light codes when repairs are complete.

• Plug into 16-pin OBDII port under dash
• Pair via BLE4.0 to iOS/Android/Windows device
• Use third-party apps (Car Scanner, Torque, OBD Auto Doctor, etc.)
• Read/erase codes and export diagnostic reports

What live data and vehicle tests can I expect with this adapter?

The iCar2 streams live parameters from the vehicle’s ECU so you can monitor engine RPM, coolant temp, fuel trim, sensor voltages and more in real time. It also supports active testing where apps allow sending commands to actuators or running built-in system checks to isolate faults faster.

• Real-time data stream and freeze-frame snapshots
• Performance tests and trip logging features
• Active ECU commands where supported by app and vehicle
• Exportable diagnostic logs for sharing with technicians

Will leaving the adapter plugged in harm my vehicle battery?

vLinker iCar2 includes BatterySaver technology and low-power modes to prevent battery drain. When idle, the adapter automatically enters sleep after about 30 minutes without a Bluetooth connection and its sleep current drops to a few milliamps, reducing risk when left connected for long-term diagnostics.

• Auto-sleep after inactivity to conserve battery
• Over-voltage, over-current and over-temperature protection
• LED status indicators for connection and power
• Operating current around 46–48mA; sleep current ~3mA

Which cars and apps work with the vLinker iCar2?

This adapter supports virtually all OBD2/EOBD-compliant 12V passenger cars and small diesel vehicles up to specified weights—standard OBD2 protocols are covered. It pairs with many popular third-party apps on iOS and Android, though apps are not included and some advanced features depend on the chosen software and vehicle model.

• Works with OBD2/EOBD compliant vehicles (see vehicle years by region)
• Compatible with Car Scanner, Torque, OBD Auto Doctor, DashCommand, Accurate, and more
• Not for 24V heavy-duty trucks or non-OBD2 systems
• App-dependent features vary by make/model/year

Who is this for: vLinker iCar2 is ideal for car owners who want to self-diagnose and log vehicle performance, mobile mechanics who need a portable scanner, and fleet or travel users who want a compact, always-ready diagnostic tool. It suits anyone comfortable installing a small OBDII dongle and using a smartphone app to interpret data, troubleshoot issues or hand over recorded reports to a repair shop.
