For car owners seeking to understand their vehicle’s health without relying solely on professional mechanics, specialized gadgets for self-diagnostics have become indispensable. These tools fall into two main categories: standalone scanners and adapters. Standalone devices operate independently, displaying diagnostic information on their built-in screens. Adapters, on the other hand, require a smartphone or tablet for setup and data visualization, typically connecting via Wi-Fi and a dedicated app.
A crucial factor when choosing an automotive diagnostic scanner is its compatibility with your car model. The market offers three types of scanners:
- Brand-specific scanners, designed to work with a single car brand.
- Multi-brand scanners, also known as universal scanners, compatible with various car brands.
- Model-specific scanners, tailored for a particular car model.
To simplify the selection process, we’ve compiled a list of the best car scanners for 2025, based on user reviews and the expert opinion of Sergey Dyachenko, owner of The Garage автосервис and auto parts store.
