TOPDON ONE Plus Professional Diagnostic Scan Tool
The TOPDON ONE Plus is a diagnostic and programming tool for professional repair shops and diagnostic specialists, with true OE-level performance and more than 50 service functions. It supports gateway access for FCA, Renault, Nissan and VAG SFD, the latest communication protocols, high-speed Wi-Fi VCI communication, AI-driven repair guidance and one-click customisation.
Handle More Repairs In-House
Professional ECU programming for BMW and VAG vehicles covers four core systems: ECM, SRS, ABS and TCM. You can program blank ECUs, update ECU versions, recover lost ECU data and back up ECU data, which raises the value of the jobs you can take on.
One-Click Customisation and Pro-Grade Coding
ECU coding for 10+ leading brands lets you match components, activate or deactivate functions and optimise vehicle efficiency. One-click customisation is built into the coding workflow for vehicle modifications and driver preference changes. Coding functions may vary by make, model and year.
OE Topology Mapping
Instead of lists of modules and systems, you get a command-centre view of the whole vehicle network, with colour-coded system status and DTC numbers, so you can visualise the troubleshooting flow and pick out faulty modules at a glance.
TopFix AI
The TopFix AI assistant analyses trouble codes and gives data-driven repair guidance in seconds, with root-cause identification, verified fixes and technical resources such as diagrams, as an actionable roadmap for each repair.
Dealer-Level Workflow with J2534
The ONE VCI works as a J2534 pass-thru device that syncs with OEM diagnostic software for 14 vehicle brands, turning a Windows PC into a multi-brand workstation. OEM software must be bought from the manufacturer's website, and DoIP system diagnostics are not supported when used with OEM software.
Next-Generation Vehicles
Integrated CAN-FD and DoIP, plus authorised support for FCA SGW, VAG SFD and Renault and Nissan gateways. Access to SGW-protected systems may need OEM credentials where applicable.
Built for a Busy Workshop
OE-level full-system diagnostics, bi-directional control and more than 50 essential service functions give faster diagnosis and more efficient service procedures.
Integrated Immobiliser Functions
Built-in IMMO support covers key services such as adding new keys, programming keys after all keys are lost and deleting old keys.
12-Parameter Live Data
Monitor up to 12 live parameters at once, with multiple graphing and combined data options, to compare sensors, spot irregular patterns and diagnose intermittent faults without switching screens.
Two Bonus Tools Included
Every ONE Plus kit includes a TopScan Master Bluetooth dongle for smartphone diagnostics and a BTMobile ProS battery tester for battery health checks.
Updates
Two years of free software updates are included.
Who It Suits
Professional repair shops that need diagnostics, ECU programming, coding and OEM software pass-thru in one system.
