Why Thinkdiag 2 with Diagzone?
Thinkdiag 2 with Diagzone is a powerful combo because it merges wide multi-brand software coverage with modern, future-ready hardware in one compact package. Together with a quality 24V to 12V converter, it becomes a single solution for both car and truck diagnostics.
Thinkdiag 2 Hardware Specifications
Thinkdiag 2 is a compact but powerful OBD2 interface designed to give workshop-level diagnostics from a small Bluetooth device. Its hardware is built around modern vehicle communication protocols, stable wireless connectivity, and a rugged body suitable for Indian workshop conditions.
Protocols and connectivity
Thinkdiag 2 supports all common OBD-II protocols along with advanced CAN-FD and DOiP, so it can communicate with new-generation BS6 and post-2020 vehicles. The device connects to Android and iOS phones or tablets via Bluetooth 5.0 dual‑mode, which offers faster pairing, better range, and a more stable link compared to older Bluetooth versions. A DB15 diagnostic interface and included OBD2 cable ensure reliable data transfer between the vehicle and the scanner.
Power, voltage range and safety
The hardware is designed for a typical 12V vehicle system with an operating voltage range of about 9–18V, making it safe for most passenger cars and light commercial vehicles. Because it is a 12V device, pairing it with a dedicated 24V to 12V converter is essential when working on trucks and buses, which protects the scanner from over‑voltage and signal mismatch. Power consumption is low (around 2W or less), so it does not put extra load on the vehicle battery during long diagnostic sessions
Build quality and design
Thinkdiag 2 uses an ABS + PC body with a TPU rubber sleeve, giving good impact resistance and grip for daily workshop handling. The compact housing (around 120.5 × 65 × 29 mm) and 0.65 m OBD cable make it easy to route around the dashboard without strain on the connector. Dual indicator LEDs on the device clearly show power and communication status, helping technicians quickly confirm that the tool is connected and active
Performance-oriented hardware features
Internally, Thinkdiag 2 is optimised for bi‑directional control and fast data refresh, which is important for active tests, adaptations and coding. Bluetooth 5.0 plus CAN‑FD support allows higher data throughput, so live data streams, full‑system scans and special functions run faster than older Bluetooth OBD adapters. Overall, the hardware gives technicians a stable platform that fully supports advanced software like Diagzone without lag or frequent disconnections.
Diagzone Software – One Platform for Car + Truck
Diagzone is a multi-platform diagnostic software that works seamlessly with GOLO, Easydiag, Thinkdiag and Thinkdiag 2, so technicians can keep using their favourite connectors with one powerful app. It covers passenger cars, heavy commercial vehicles and many EV brands, giving workshops a single software solution for almost every type of vehicle that enters the bay.

Broad hardware compatibility
Diagzone is officially built to work with popular Launch‑type Bluetooth connectors like Golo EasyDiag, Easydiag series, Thinkdiag and Thinkdiag 2, as well as some X‑431 style adapters. This means you can upgrade your software capabilities without buying a new scanner each time, which is cost‑effective for small and mid‑size garages.
Global vehicle coverage – Cars
Diagzone offers full‑system diagnostics for cars from all major regions, including USA (Chrysler, Dodge, Jeep, GM, Chevrolet, Cadillac, Buick, Ford, Lincoln, Tesla, GMC), UK (Aston Martin, Land Rover, Jaguar, MINI, Rolls Royce, Bentley, Vauxhall, Rover) and Europe (Audi, BMW, Mercedes‑Benz, Maybach, VW, Porsche, Skoda, Seat, Citroen, Peugeot, Renault, Dacia, Fiat, Abarth, Alfa Romeo, Lancia, Saab, Volvo, Ferrari, Maserati, Bugatti, Lamborghini, Opel). Asian coverage includes Toyota, Lexus, Honda, Acura, Nissan, Infiniti, GTR, Mazda, Subaru, Suzuki, Mitsubishi, Hyundai, Genesis, Kia, Isuzu, Ssangyong, Proton, Perodua and a long list of Chinese OEMs such as BYD, Geely, GWM, Changan, JAC, JMC, Chery, Exeed, Omoda, Haval, Wuling, Roewe, MG and Vinfast. For India and Australia, it supports Maruti, Tata, Mahindra, Force, AUST Ford, Ford Australia and Holden, including India‑specific and Australia‑specific variants.
Global vehicle coverage – Trucks and buses
On the heavy‑duty side, Diagzone covers major US brands like Freightliner, International, Peterbilt, Kenworth, Western Star, Sterling, Mack, Bluebird, ThomasBuilt, Autocar and several bus/coach lines. European and Asian coverage includes MAN, DAF, Scania, Volvo, Renault HD, Iveco, Mercedes‑Benz HD, Ashok Leyland, Eicher, Tata HD, Mahindra HD, Hino, Fuso and many Chinese heavy truck and bus manufacturers such as DongFeng, FAW, Sinotruk, Shacman, Yutong, Kinglong and more. In India and Australia, there is specific support for Ashok Leyland, BharatBenz, Eicher, Tata heavy duty and a range of export Volvo/Scania/Isuzu/Hino/Fuso models.
EV and new-energy vehicle support
Diagzone also includes coverage for selected electric and hybrid vehicles, adding dedicated functions for battery and high‑voltage systems on supported brands listed in its TD2 software catalogue. This makes it suitable for workshops that are starting to see EVs and plug‑in hybrids along with traditional petrol and diesel vehicles.
Full-system diagnostics and reset functions
The software supports full‑system scanning, reading/clearing codes and live data on engine, transmission, ABS, airbag, BCM, instrument cluster and more for supported vehicles. It offers a very large library of service and reset functions, including oil and service reset, EPB, DPF regeneration, injector coding, throttle adaptation, battery matching and dozens of other maintenance resets similar to the list you provided (AC relearn, AdBlue, SAS, TPMS, sunroof, suspension, windows, etc.).
Programming, coding and special functions
Diagzone goes beyond basic resets by enabling ECU coding, adaptation and special functions on many brands, so technicians can configure modules, perform key/IMMO functions and carry out component calibrations. Combined with bi‑directional tests, it allows active control of components (like fans, pumps, valves and actuators) to speed up fault finding and confirm repairs.
Who Should Buy This Package?
This Thinkdiag 2 + Diagzone + 24V converter package is ideal for anyone who wants one setup to handle both cars and trucks with advanced functions at an affordable price. It suits users who prefer working from a smartphone or tablet instead of a bulky traditional scanner.
Small and mid-size multi-brand workshops
Independent garages that see a mix of Indian, Asian, American and European cars will benefit from the wide vehicle coverage and full-system diagnostics. Workshops that also get occasional trucks and buses can add the converter and unlock heavy-duty diagnostics without buying a separate truck scanner.
Truck and bus workshops
Truck repair shops and diesel specialists who already handle brands like Ashok Leyland, Tata, BharatBenz, Eicher, Volvo, Scania, MAN and others can use this combo as a main or secondary diagnostic tool. It is especially useful for workshops that need one device to cover both HD trucks and the owner’s or customer’s personal cars.
Mobile technicians and roadside assistance
Mobile mechanics and on-site service providers can carry Thinkdiag 2, a phone/tablet and the 24V converter to handle breakdown diagnostics on cars, pickups, buses and trucks. The compact hardware and Bluetooth connection make it convenient for quick fault finding and basic programming without lugging a large trolley scanner.
Fleet owners and transport companies
Fleet operators running mixed fleets (cars for staff plus trucks/buses for logistics or passenger transport) can use this package to monitor vehicle health in-house. It helps fleets read faults, perform DPF regen and resets, and decide when a vehicle truly needs to go to an outside workshop, reducing downtime and unnecessary repair bills.
Advanced DIY users and automotive enthusiasts
Enthusiasts who work on their own cars and maybe a few relatives’ or friends’ vehicles, and want more than just a basic code reader, will appreciate the bi-directional tests and special functions. For users planning to grow into part-time or full-time diagnostic work, this package offers a strong foundation that can handle everything from simple code reading to coding and adaptations
