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.
