Frequently Asked Questions (FAQ)

Key Information About DevCom Diagnostics.

Have questions about our diagnostics? Here’s an overview of the most common questions and answers to help you choose, use, and troubleshoot our products. If you can’t find what you need, feel free to contact us.

Safety and Usage

Is it safe to use the diagnostic device on my vehicle?

Yes, using the diagnostic device under normal conditions is entirely safe for your vehicle. It simply reads data from the control units without affecting engine performance or the original software.

However, it is important to note that some advanced functions, such as coding, adaptations, or value rewriting, can lead to incorrect data being stored in the control unit if used improperly. Therefore, we recommend that these operations be carried out only by qualified mechanics or specialists with the appropriate experience.

Can I try the diagnostic device before purchasing?

Of course! Just contact us by email obchod@devcom.cz or through the form below, and we’ll arrange the terms for borrowing any diagnostic tool with software according to your needs.

Compatibility and Features

Does the diagnostic work with the newest cars?

We always strive to keep up with the times and have new software ready for the latest cars as soon as possible. Typically, implementing new diagnostic software takes about 1 to 1.5 years, depending on the number of new functions, control units, and changes in vehicle communication systems.

Can the diagnostics also cover the automatic transmission, ABS, or airbags?

Unlike many basic diagnostic tools on the market, our devices are not just simple engine code readers. With TSPro and Troodon diagnostics, you can access data from all control units in the vehicle — including airbags, ABS, transmission, brake electronics, and many more.

In addition to reading fault codes, you can also perform advanced service functions such as resetting service intervals, regenerating the DPF, releasing the parking brake, and much more.

Can the diagnostics reset service intervals?

Yes, our diagnostics support all basic and advanced service functions. In addition to resetting service intervals, you can also perform functions such as resetting adaptation values, regenerating the DPF, coding injectors, or releasing the electronic parking brake.

Can the diagnostics reflash or update ECU firmware?

No, this function is not supported. Our diagnostic system is designed specifically for reading fault codes, measuring values, and handling standard service operations.

Firmware flashing is a very sensitive process that carries the risk of irreversibly damaging the control unit, especially if non-original or unverified files are used. This procedure should always be performed only with official tools and software obtained directly from the vehicle manufacturer.

Updates and support

Do I have to update every year?

No, updates are optional. We release new updates annually, but you decide if and when to install them.

Customers set their own pace — if you skip one or more years, you can always update later and catch up on all changes from previous years. More details about updates can be found in the Updates section.

Do you provide technical support or guides?

Yes, our customers can access complete technical support, via phone or online.

Every diagnostic system includes manuals, which can also be accessed online in the Support section.

Do you also provide service data?

Yes, we offer a wide range of service data, including access to the ALLDATA – one of the world’s largest sources of original (OEM) information.

The ALLDATA digitizes technical documentation directly from vehicle manufacturers and is now used by more than 300,000 professional technicians worldwide. Users can find service procedures, wiring diagrams, maintenance data, technical service information, and other essential resources for efficient vehicle repair and maintenance.

Technical Requirements and Connectivity

Do I need any special cables or adapters?

In most cases, no. Most passenger cars connect via a standard OBD connector, which is included with all our diagnostic devices.

For older vehicles, motorcycles, trucks, or buses, special cable adapters may be required — all of which are available in our offer. Our team can help you choose the right adapters for your specific vehicle.

Do I need special software or an app to use the diagnostic device?

Yes, our diagnostics come with dedicated software, which is available free of charge.

For personal computers, we offer the Diag Center application, and for mobile devices (Android and iOS), the Troodon OBD app. Both are developed specifically for our diagnostic devices to ensure full functionality and easy operation.

Does the device work without an internet connection?

Yes, the device works fully offline for nearly all operations — you can read and clear faults, monitor live data, and perform advanced service functions without any connection.

Internet access is only needed for certain online features like Security Gateway (SGW) unlocks, remote diagnostics, or software updates.

Which operating systems are supported?

Our diagnostics support Windows, Android, and iOS.

The Diag Center application is designed for Windows (PC), while the Troodon OBD mobile app is available for Android and iOS devices.

Is the application available in English?

Yes, our diagnostic applications offer support for the English language.

In addition, other languages are also available, such as Czech, German, Italian, and Polish, so users can choose the language according to their preferences.

Where does the device connect?

The device typically connects to the OBD port (On-Board Diagnostics), which is standard in most vehicles manufactured after 2001.

The Diag Center app indicates the typical location of the OBD port for each vehicle. It’s usually under the steering wheel, near the fuse box, or in the center console. If you’re unsure, our team can help you locate it.

Everything we do follows one main rule: diagnostics must serve you — not the other way around. That’s why we focus on easy operation, intuitive navigation, and technical support whenever you need it.
