The TOPDON ONE Plus is built for the pace of a working shop. OE-level full-system diagnostics, bidirectional control and more than 50 service functions, with a high-speed Wi-Fi VCI and AI-driven diagnostics to keep vehicles moving.
50+ maintenance functions and integrated IMMO
Diagnose faster, finish service jobs and keep the bay turning over. Built-in IMMO support lets you add keys, program after all keys lost, and delete old keys from the same tablet.
Professional ECU programming
ECU programming on BMW and VAG across four core systems — ECM, SRS, ABS and TCM. Program blank ECUs, update ECU versions, recover lost ECU data and back up ECU data.
*Programming coverage varies by vehicle.
One-click customisation and pro-grade coding
ECU coding on 10 leading brands. Match components, switch functions on or off, and change driver preferences with one-click customisation in the coding workflow.
*Coding functions vary by make, model and year.
OE topology mapping
See the whole vehicle network on one screen. Colour-coded system status and DTC numbers so you can find a dead module without working through long module lists.

CAN-FD and DoIP are built in, with authorised support for FCA SGW, VAG SFD and Renault/Nissan gateways. Manufacturer subscriptions may be required on some vehicles.
