• Item/Model
• The ONE Lite gives technicians dealer-level control over coding tasks. Adjust vehicle settings, match new modules, initialize components, and access features that typically require OE tools. It's a straightforward way to handle replacements, personalization, and system updates with confidence.
• The ONE Lite supports more than 50 maintenance functions, including resets, adaptations, and calibrations used in routine service work. Functions include Oil/BMS/EPB resets, DPF regeneration, Dynamic ADAS calibration, camshaft learning, relative compression, and other system-specific procedures needed in daily repair operations.
• The TOPDON ONE Lite also functions as a J2534 Pass-Thru programmer, allowing technicians to perform OEM software updates and module programming. When connected to a laptop, the ONE VCI serves as the communication interface between the vehicle and the OEM software.
• The TOPDON ONE Lite supports CAN-FD and DoIP communication protocols for compatibility with newer vehicle networks. Coverage includes 2013+ BMW, 2016+ VW and Volvo, 2017+ Jaguar, 2018+ Mercedes-Benz, 2020+ GM and Chrysler models, and other systems that rely on advanced communication standards.
• The TOPDON ONE Lite supports authorized support for FCA, Renault, Nissan, and other SGW-equipped models. Gain access to coding, active tests, clearing codes, and system-level service functions on supported vehicles. Compatibility includes current and upcoming SGW implementations.
• Access to SGW-protected systems may require OEM credentials where applicable.
• The TOPDON ONE Lite uses dual Wi-Fi modules to maintain stable communication and high-speed data transfer between the tablet and VCI. This design provides a faster, more responsive experience than Bluetooth-based connections, especially during system scans, live data viewing, and coding operations.
• The TOPDON ONE Lite uses an 8-core processor to handle multi-system scans, coding operations, and large volumes of live data without delays. The added processing power keeps the interface responsive during complex or extended diagnostic workflows.
• The TOPDON ONE Lite performs full-system scans across more than 120 vehicle brands, including reading and clearing fault codes, checking system status, and reviewing module broad coverage supports comprehensive diagnostic work across a wide range of makes and models.
• View up to 12 live parameters simultaneously for easier comparison. Sorting and grouping options allow technicians to analyze sensor behavior and system performance with clarity during diagnostic work.
• The TOPDON ONE Lite generates structured diagnostic reports that include fault codes, module status, and test results. Save and share reports with customers or internal teams for documentation and repair planning.
• The TOPDON ONE Lite is compatible with BTMobile ProS, allowing shops to expand their services to include true, in-depth battery diagnostics. Perform overall health, charging, cranking, state of health, and state of charge tests to get to the heart of customer battery conditions.

Full function support on SGW cars is what keeps a modern FCA job from stopping at the gateway.
