TOPDON ONE Plus - Diagnostic Tablet with Wireless J2534 VCI

ONE Plus for workshop diagnostics

TOPDON ONE Plus is a 10.1-inch diagnostic tablet with a wireless Wi-Fi connection to its VCI. On supported vehicles it reads and clears fault codes, performs bidirectional tests and compares up to 12 live parameters. The topology view links control-unit status with fault codes, helping technicians review the vehicle's communication network.

Service functions and data analysis

More than 50 service functions cover categories such as oil-service reset, electronic parking brake service, battery registration and throttle adaptation. Coding and programming are available for supported ECUs. TopFix AI assists with code interpretation and further checks; its suggestions do not replace measurements or a technician's diagnosis.

Protocols and manufacturer access

CAN-FD and DoIP are supported in the tool's own diagnostic environment. J2534 operation uses a compatible Windows computer and separate OEM software. TOPDON states that DoIP diagnostics are not supported in this OEM-software mode. Protected gateways may require additional user credentials, while online functions including topology, coding and TopFix AI require an internet connection.
