ANALYTICAL REVIEW OF EXISTING VEHICLE DIAGNOSTIC SYSTEMS

Abstract

The article emphasizes the importance of carefully choosing an application that will provide accurate and timely diagnostics so that the driver can prevent possible malfunctions and keep the car in good condition. Special chip-based adapters transmit data from an electronic control unit (ECU) to a smartphone, where they are analyzed by applications. The author highlights the most popular diagnostic applications such as ScanMaster Lite, OBD AutoDoctor and EOBD2 Facile, describing their functionality, advantages and disadvantages. It is noted that many applications suffer from interface problems, difficulty of use and the need to purchase paid versions for full access to the functionality. Some of them are poorly optimized, which leads to freezes and slow command processing. In addition, many applications are highly targeted, which limits their compatibility with certain car brands.
