PTT Parameters Description is a lightweight offline reference utility that helps you quickly find and read parameter meanings by searching either Parameter Code or Parameter Caption. The interface provides a fast table view with key columns (ParameterCode, ParameterCaption, LevelId, Description, Mask, Number), so you can identify common configuration items and limits without scrolling through long lists manually.
It is designed as a reference and explanation tool. It does not replace a diagnostic application and it does not communicate with a vehicle by itself.
