Launch X431 Pro3 Link: Complete Modular Diagnostic Solution for Indian Workshops

The Launch X431 Pro3 Link is a dual diagnostic mode scanner designed for modern Indian technicians who want one tool for cars, SUVs, and commercial vehicles. It combines a powerful Android tablet, SmartLink VCI, J2534 passthrough, 39+ reset functions, modular add-on options, and strong vehicle coverage in a single platform.

What Is Launch X431 Pro3 Link?

The X431 Pro3 Link is a professional diagnostic system made of two core parts: a rugged 10.1‑inch Android tablet and the SmartLink C V2.0 VCI (vehicle communication interface). The tablet runs Launch diagnostic software, while the SmartLink VCI connects to the vehicle and supports modern protocols including J2534, CAN FD, and DoIP, so you can work on the latest vehicles.

This tool supports dual diagnostic modes. In local mode, you perform all diagnostics directly from the tablet, even without internet. In SmartLink remote mode, you can connect a master technician or OEM specialist over the internet to perform remote coding, programming, or complex troubleshooting on your customer’s car.​

Tablet & VCI Specifications

The Pro3 Link tablet runs Android 10.0 with a 2.0 GHz quad‑core CPU, 4 GB RAM, and 64 GB internal storage, giving enough power to handle big databases and live data smoothly. The 10.1‑inch 1280×800 capacitive touchscreen, 6300 mAh battery, Wi‑Fi (2.4/5 GHz), Bluetooth, USB‑A and USB‑C make it practical for all‑day workshop use.​

The SmartLink C V2.0 VCI has its own processor, 256 MB memory, 8 GB storage and a 3.95‑inch status display, and supports 9–36 V working voltage to cover both 12 V cars and 24 V trucks. It handles OBD‑II, UDS, KWP2000, CAN, CAN FD, LIN, K‑Line and DoIP, and works as a certified J2534 passthrough interface for OEM applications on your laptop.

J2534 Passthrough & OEM Software

With J2534 support, you can run OEM diagnostic and programming software (like OEM portals for VW, Toyota, etc.) on your laptop and use the SmartLink VCI as a passthrough device. This lets you perform ECU flashing, software updates, module replacement, immobilizer and advanced coding using original manufacturer software instead of buying separate OEM scan tools.​

For an Indian workshop, this means dealership‑level capabilities with a single investment: use Launch software for fast daily work and switch to OEM software via J2534 whenever a case demands factory procedures.

41 Reset & Service Functions

The Pro3 Link supports more than 41 special functions, grouped across key vehicle systems.​

• Engine & Emissions: Oil service reset, injector coding, DPF regeneration, throttle relearn, EGR adaptation, NOx reset and other powertrain resets.​

• Transmission & Drivetrain: Gearbox relearn, clutch matching, differential/turbo matching and related adaptations for smooth shifting and power delivery.​

• Brake System: EPB reset, ABS bleeding, brake pad wear reset, hydraulic/ESP calibrations for safe brake performance after repairs.​

• Battery & Power: Battery registration/matching, alternator reset and stop‑start system reset when you replace battery or charging components.​

• Steering & Suspension: Steering angle sensor calibration, suspension height calibration and motor angle reset after alignment or suspension work.​

• Body & Comfort: TPMS reset, window/sunroof learning, seat occupancy calibration, AC system initialization and transport mode on/off.​

• Advanced: ECU reset and high‑voltage battery diagnostics for hybrid/EV platforms, expanding future‑ready coverage.​

These guided functions reduce trial‑and‑error and make complex tasks like DPF regen, injector replacement or steering calibration safe for everyday technicians.

Modular Platform: Add‑On Modules

The X431 Pro3 Link is a modular platform, so you can attach professional add‑ons as your workshop grows.​

• VSP‑600 / VSP‑200 Oscilloscope: For waveform analysis and in‑depth electrical diagnostics.

• S2‑2 SensorBox & O2‑2 ScopeBox: For sensor simulation, signal tracing and component testing.

• X431 Key Programmer: For immobilizer, remote, and smart key programming.

• Battery Tester / BST360: For battery health checks and charging/starting system analysis.

• Wi‑Fi Printer: For printing diagnostic reports directly from the tablet.

• EV Clamp and other EV tools: For high‑voltage and electric vehicle diagnostics.​

Because everything is from the same ecosystem, modules plug into the software menu and work without messy third‑party integrations.

Vehicle Coverage & Indian Focus

Launch lists full system coverage for over 110 brands across American, European and Asian markets, with continuous online updates. The tool is well‑tuned for India, covering Maruti Suzuki, Tata, Mahindra, Hyundai, Kia, Toyota and almost all common Indian models for engine, ABS, airbag, transmission and body systems.​

With SmartLink C HD and appropriate license, the same platform can be extended for light, medium and heavy commercial vehicles such as Tata trucks, Ashok Leyland, Eicher and BharatBenz, making it ideal for workshops that service both cars and trucks. VW and Audi get special guided functions: Launch advertises over 30,000 guided operations for these brands, helping technicians follow OEM‑style steps in Indian conditions
