ELM327 OBD2 Reader: A Comprehensive Diagnostic Solution
The Car Scanner app, combined with an ELM327 OBD2 adapter, provides a suite of features that were previously only accessible to professional mechanics. This powerful combination allows you to:

Diagnose and Reset Fault Codes
Diagnose and reset Diagnostic Trouble Codes (DTCs) just like a professional scan tool. The app includes a comprehensive database of DTC descriptions, helping you understand and address potential issues.
Read Freeze Frame Data

Choosing the Right ELM327 OBD2 Adapter
While Car Scanner offers a wide range of features for free, unlocking its full potential requires a one-time purchase or a subscription. The app requires a Wi-Fi or Bluetooth 4.0 (Bluetooth LE) compatible ELM327 adapter. Recommended brands include Kiwi 3, Viecar, V-Gate, Carista, LELink, and Veepeak.
Avoid cheap, generic ELM327 adapters, especially those marked as v2.1, as they often have connectivity issues and can negatively impact vehicle performance. Invest in a reliable adapter for a seamless and accurate diagnostic experience.
