What You Can Do with the TOPDON ONE Plus
Diagnose Faults
Read and clear fault codes, analyze live data, and use bidirectional tests to actively control components. Live data can be displayed with up to 12 parameters simultaneously. TopFix AI enhances the diagnostic process with information about possible causes, repair suggestions, and technical information.
Analyze Vehicle Networks
OE topology graphically displays supported control units and their status. This makes troubleshooting easier, especially when multiple systems report communication or network faults at the same time.
Code, Adapt and Program
Depending on the vehicle, the TOPDON ONE Plus supports ECU coding, adaptations, and programming functions. For supported BMW and VAG vehicles, additional programming functions are available directly through the TOPDON software.
Service Work and Keys
More than 50 service and reset functions cover many common workshop tasks. IMMO functions are also available, including adding or deleting keys and, on supported vehicles, additional functions up to All-Keys-Lost applications.
ECU Programming for BMW and VAG
An important difference compared with many conventional diagnostic tablets is the integrated ECU programming of the TOPDON ONE Plus for supported BMW and VAG vehicles. Certain programming tasks can be performed directly through the TOPDON software without necessarily requiring a separate laptop with manufacturer software.
- Programming of supported control units
- Programming of compatible blank replacement control units
- Software updates for supported control units
- Backup of supported ECU data
- Recovery of supported control units
The exact range of functions depends on the vehicle, model year, control unit, and software support. Check critical programming functions for the specific vehicle before purchase.
Practical Example: Installing a Replacement ECU on a BMW or VAG Vehicle
A simplified typical workflow for a supported vehicle and control unit. The actual steps are specified by the software according to the vehicle.
-
Back Up the Old ECU Data
If the existing control unit is still communicating and the function is supported, relevant data can be backed up before replacement. -
Stabilize Vehicle Voltage
Before programming, a suitable battery support charger should be connected. A voltage drop during programming can interrupt the process and may damage or render the control unit unusable. -
Program the Replacement ECU
For supported applications, a compatible new or blank replacement control unit can be programmed with the required software. -
Code, Adapt and Verify
After programming, coding or adaptations can be performed where required and supported. Fault memory and ECU communication can then be checked again.
ECU Coding and Adaptations
ECU Coding
The TOPDON ONE Plus supports coding and adaptations on compatible vehicles. Depending on the vehicle, available functions can be activated or deactivated and supported parameters can be adjusted.
One-Click Customization
For supported vehicle brands and models, convenient customization functions are available, allowing certain vehicle options to be changed without complex manual coding.
Available coding and adaptation functions depend on the vehicle brand, model, model year, equipment, and control unit.
J2534 Pass-Thru for OEM Software
In addition to the integrated TOPDON diagnostic software, the ONE Plus provides J2534 Pass-Thru. The compatible diagnostic interface can therefore be used as a communication interface between the vehicle and supported OEM software on a Windows PC.
J2534 as an Interface
J2534 is used by various vehicle manufacturers for diagnostic, flashing, and programming procedures. The functions actually available are determined by the respective OEM software and vehicle manufacturer.
OEM Access Sold Separately
Manufacturer software, OEM portals, online subscriptions, login credentials, and any required manufacturer licenses are not automatically included with the TOPDON ONE Plus and may need to be obtained separately.
Note: According to TOPDON, DoIP is not supported when using OEM software via J2534. DoIP support within TOPDON’s own diagnostic software is independent of this limitation.
TopFix AI – AI-Powered Diagnostic Assistance
TopFix AI assists diagnostic technicians in evaluating diagnostic information. Instead of simply displaying a fault code, it can provide additional information about possible causes, repair approaches, and technical information.
Understand Faults More Effectively
TopFix AI can combine diagnostic information and help narrow down possible causes of a fault more efficiently.
Support During Repairs
Depending on the available data, information about possible repair procedures and technical details can support further troubleshooting.
TopFix AI is a diagnostic assistance tool. The actual cause of a fault should always be confirmed through proper testing on the vehicle.
OE Topology for Complex Vehicle Networks
Modern vehicles contain numerous interconnected control units. The OE topology of the TOPDON ONE Plus graphically displays supported control units and their communication structure.
This makes it easier to identify which control units are accessible and which systems are reporting faults. Especially when several communication faults occur simultaneously, the graphical view provides a much clearer overview than a conventional control unit list.
Topology display and coverage depend on the vehicle.
Bidirectional Tests for Active Troubleshooting
With bidirectional or active tests, the TOPDON ONE Plus can send commands directly to supported control units. This allows components to be activated individually and their operation to be checked.
Depending on the vehicle, components such as fans, pumps, relays, lights, power windows, actuators, and other systems can be controlled. This makes it easier to determine whether a problem is caused by the component itself, its control circuit, or another part of the system.
Available active tests depend on the specific vehicle and control unit.
50+ Service Functions for Everyday Workshop Tasks
The TOPDON ONE Plus supports more than 50 service, maintenance, adaptation, and reset functions. Depending on the vehicle, these include for example:
- Oil service completedReset service interval
- Brake pads replacedEPB service
- New battery installedBattery registration / BMS
- Steering or suspension work completedSteering angle sensor calibration
- Throttle body cleaned or replacedThrottle adaptation
- Injector replacedInjector coding
- DPF service requiredDPF regeneration
- Work performed on the ABS systemABS bleeding
- Transmission work completedTransmission adaptation
- Tire pressure system servicedTPMS service
Availability and procedures for individual service functions depend on the vehicle.
IMMO and Key Programming
The TOPDON ONE Plus also provides IMMO and key functions for supported vehicles. Depending on the vehicle platform, keys can be added or deleted and additional immobilizer functions can be performed.
All-Keys-Lost functions are also available for certain supported vehicles.
Important: IMMO and key programming functions are highly vehicle-dependent. Check the required function for your specific vehicle before purchase.
CAN FD, DoIP and Security Gateway
The TOPDON ONE Plus supports modern diagnostic protocols and access methods for many current vehicle platforms.
- CAN FD on compatible vehicles
- DoIP within supported diagnostic applications
- FCA Security Gateway (SGW)
- VAG SFD
- Renault and Nissan Gateway
For Renault and Dacia vehicles with Security Gateway, we offer suitable TOPDON access cards and updates.
