TOPDON ONE Lite Professional Diagnostic Scan Tool
The TOPDON ONE Lite is a fast, accurate diagnostic tool with a VCI, built for dealer-level functions, repair guidance, network mapping and modern communication protocols. It scans across 120+ vehicle brands from a 10.1 inch Android 12 tablet.
ECU Coding for 10+ Brands
Dealer-level ECU coding covers 10+ brands, including BMW, Mercedes-Benz, VAG, Nissan, Toyota, Porsche and PSA. You can adjust vehicle settings, match new modules, initialise components and access features that usually need OE tools, which suits module replacement, personalisation and system updates.
OE-Level Topology
An OE-style map of every module shows how the systems communicate, where faults appear, how modules are interconnected, the active DTC count and the problem areas, so you can find a faulty module at a glance.
TopFix AI
A built-in AI assistant interprets fault codes and streamlines diagnosis. It gives fault code explanations, likely causes, related symptoms and structured repair steps in one view, with wiring diagrams and technical references alongside the data when available.
50+ Maintenance Functions
More than 50 functions cover resets, adaptations and calibrations, including oil reset, BMS reset, EPB reset, DPF regeneration, dynamic ADAS calibration, camshaft learning and relative compression.
CAN-FD and DoIP
Support for these advanced protocols covers newer vehicles, including 2013+ BMW, 2016+ VW and Volvo, 2017+ Jaguar, 2018+ Mercedes-Benz and 2020+ GM and Chrysler.
Security Gateway (SGW) Access
Authorised access to SGW-equipped models from FCA, Renault, Nissan and others supports coding, active tests, clearing codes and system-level service functions, for current and upcoming gateway systems. Access to SGW-protected systems may need OEM credentials where applicable.
Speed and Performance
-
Dual Wi-Fi between the tablet and VCI is more responsive than Bluetooth, especially during scans, live data and coding
-
8-core processor keeps the interface responsive in long or complex sessions with multi-system scans, coding and large amounts of live data
Complete Module Scans for 120+ Brands
Full-system scans read and clear fault codes, check system status and review module communication across 120+ vehicle brands.
Live Data and Reporting
-
Live data shows up to 12 parameters at once, with sorting and grouping to compare sensor behaviour
-
Diagnostic reports with fault codes, module status and test results can be saved and shared with customers or your team
Optional Battery Testing
Pair the ONE Lite with the BTMobile ProS (sold separately) for battery health checks, voltage tests and basic performance evaluation.
Updates
The first year of software updates is free. After that, renewal plans apply.
Who It Suits
Workshops that want full-system diagnostics, coding and 50+ service functions on newer vehicles.
