vLinker VGATE vLinker MC+ Bluetooth OBD-II Adapter — OBD2 Scanner & Code Reader, Dual-Mode BT for iOS/Android/Windows

vLinker VGATE MC+ is a compact Bluetooth OBD-II adapter that turns your phone, tablet, or PC into an all-systems diagnostic scan tool for reading and clearing vehicle fault codes and running active tests.

The VGATE vLinker MC+ plugs into any standard OBD-II port and uses dual-mode Bluetooth (BT3.0 + BLE4.0) to stream manufacturer-level data to compatible apps on iOS, Android, or Windows. Built for both DIY car owners and professional technicians, it supports extended frame communications, SW-CAN and MS-CAN protocols, and provides battery-protecting sleep modes so it can safely remain connected during trips or troubleshooting.

How does the MC+ read and clear engine codes?

The MC+ follows established OBD-II command sets (ELM/STN compatible) to request diagnostic trouble codes from your vehicle's ECU, display the codes in your chosen app, and send clear commands to turn off fault indicators when repairs are complete. It supports long-frame messages and higher baud rates for smoother communication with complex modules.

• Reads generic and manufacturer-specific fault codes through supported apps.
• Sends clear commands to reset check engine lights from your device.
• Handles large data frames (up to 1024 bytes) and higher baud rates for stability.

Can the MC+ perform active tests or bi-directional control?

Yes — when used with apps that expose bi-directional features, the adapter can send commands back to vehicle systems for active testing. This allows you to actuate components and confirm faults without swapping parts, helping diagnose the root cause faster.

• Supports bi-directional control via app-driven ECU commands.
• Useful for triggering relays, valves, and sensors during diagnosis.
• Functionality depends on the diagnostic app you choose.

What vehicles and protocols does the MC+ support?

The MC+ works with the five standard OBD-II protocols plus SW-CAN and MS-CAN, expanding access to certain GM and Ford proprietary networks. It is compatible with most cars and light trucks sold in markets that use the OBD-II connector, and interfaces with many popular ELM/STN-based apps on mobile and PC platforms.

• Compatible with standard OBD-II protocols and SW-CAN/MS-CAN networks.
• Works with apps that use ELM327/ELM329 and STN command sets.
• Connects to iOS (BLE), Android (BT+BLE), and Windows devices.

How does the MC+ protect vehicle battery and stay reliable during use?

vLinker designed the MC+ with built-in power management and safety features so it can remain plugged into the vehicle without draining the battery. Auto sleep/wake, low idle current, and over-voltage/over-temperature protections reduce risk during extended monitoring or logging sessions.

• Auto sleep/wake reduces power consumption when idle.
• Low sleep current (around 3 mA) prevents battery drain.
• Protection circuits guard against over-current, over-voltage, and overheating.

Who this is for: The vLinker VGATE MC+ is aimed at car enthusiasts, mobile mechanics, and small repair shops that want a portable, app-driven diagnostic interface. It fits DIYers who prefer hands-on troubleshooting, techs who need manufacturer-network access like SW-CAN/MS-CAN, and anyone wanting an affordable way to read codes, log trips, and run active tests using their smartphone or laptop. The device ships with a one-year warranty, lifetime free updates, and tech support to assist with connectivity and app compatibility.
