✅ INITIAL CONFIGURATION

When turned on, the TOPDON ArtiDiag Pro boots up with Android 10.0 and a multilingual interface. Here are the first steps:

1. Connect the device to the OBD2 cable and to the vehicle socket (usually under the steering wheel).
2. Turn on the instrument panel without starting the engine.
3. Connect to a Wi-Fi network and activate your TOPDON account (this will be used for updates and encryption).
4. Select the Italian language and set the correct time zone.
5. Run the initial update check from the “Update” menu.

🔌 CONNECTION TO THE VEHICLE

The ArtiDiag Pro draws power directly from the vehicle's OBD2 port, eliminating the need for external batteries. Once connected:

• The device automatically recognizes the VIN (AutoVIN function) and identifies the make and model.
• Alternatively, you can manually select the vehicle from the “Diagnostics” menu.
• Press “Auto Scan” to start reading all ECUs.

👉 Tip: Leave the ignition on but do not start the engine during the diagnosis, to avoid voltage errors.

🧠 PERFORM A COMPLETE DIAGNOSIS

From the main menu, select Diagnosis → Automatic Scan . The TOPDON ArtiDiag Pro will scan all vehicle ECUs (engine, ABS, airbag, TPMS, infotainment, transmission, body computer, etc.)

While scanning you can:

• View trouble codes (DTCs) and their descriptions in Italian.
• Clear DTCs after repair.
• Check real-time data such as engine RPM, battery voltage, temperatures, lambda sensors, EGR, etc.
• Record and save data for later comparison.

Pro Tip: Use “Data Stream” mode to compare real-time parameters between two sensors and identify irregularities (e.g. front/rear lambda probe).

🧾 SERVICE AND RESET FUNCTIONS

In the "Services" menu, you'll find over 35 preset maintenance functions . The main ones include:

• Oil reset and maintenance intervals.
• Reset EPB (electronic parking brake).
• Steering Alignment (SAS) .
• Battery Management System (BMS) for AGM or EFB replacements.
• DPF regeneration for PSA, Fiat, VW and Ford diesel engines.
• Injector learning and gearbox adjustment reset.

These procedures can be safely performed even by experienced users, but it is always recommended to check the parameters before erasing data .

⚙️ BIDIRECTIONAL TESTS AND ACTIVATIONS

One of the strengths of the TOPDON ArtiDiag Pro is the bidirectional control , which allows you to manually operate components to check their correct functioning:

• Enabling cooling fans.
• Fuel pump and EGR valve test.
• Control of windshield wipers, locks, lights, etc.

This type of test allows you to understand whether the problem comes from the component or the control unit.

📲 SOFTWARE UPDATES

From the "Update" menu, you can update diagnostic modules online via Wi-Fi. Updates are free for 2 years and add new vehicle makes or models.

⚠️ Do not disconnect your device during the update and make sure you have at least 50% battery in your vehicle.

💡 PRACTICAL WORKSHOP TIPS

• Always perform a basic diagnosis before complex interventions.
• Use the PDF Report function to archive customer diagnostics and ECU data.
• After a reset or adaptation, always check the learned values ​​with the Live Data function.
• Avoid coding on vehicles with voltage below 12V.
