## What is Elm327 WiFi Codes?

Elm327 WiFi Codes is a simple and convenient OBD-II trouble code reference designed for drivers, car owners, mechanics, and automotive enthusiasts.

Enter a diagnostic trouble code such as P0300, P0420, or P0171 to quickly view its meaning and possible causes.

MAIN FEATURES

• Fast OBD-II trouble code lookup
• Support for P, B, C, and U code categories
• Detailed descriptions of common diagnostic codes
• Possible causes for frequently encountered faults
• Recognition of generic and manufacturer-specific codes
• Built-in offline code database
• Additional web search option
• Clear and easy-to-use interface
• Automatic detection of the device language
• Manual language selection saved between sessions

SUPPORTED LANGUAGES

English, Polish, German, French, Spanish, Portuguese, Russian, Ukrainian, Dutch, Italian, Czech, Lithuanian, and Latvian.

The built-in database works without requiring an account. For manufacturer-specific codes, the exact meaning may depend on the vehicle make, model, year, engine, and control module.

Elm327 WiFi Codes is a reference and code lookup application. The current version does not connect directly to an ELM327 adapter and does not read or clear codes from a vehicle.

Diagnostic trouble codes indicate the system in which a fault was detected. They do not always identify the exact component that must be replaced. Verify the result using appropriate vehicle diagnostics and service information.
