## What is OBD Expert?

OBD Expert App is a professional vehicle diagnostic tool designed for car owners and maintenance personnel, focusing on two core functions: maintenance reset (i.e., oil reset) and deep OBD diagnosis, with easy operation and wide compatibility. The maintenance reset function can accurately reset the vehicle’s oil maintenance reminder; after changing the oil, you can operate it with one click to avoid misjudgment of maintenance prompts, ensuring the vehicle’s maintenance cycle is accurately controllable, without the need for professional equipment or store operations, saving time and effort. The deep OBD diagnosis function can fully read vehicle diagnostic trouble codes (DTC), freeze frame data, analyze the operating status of each system, interpret potential faults, provide clear fault descriptions and basic handling suggestions, help detect vehicle hidden dangers in advance, and reduce maintenance costs. Compatible with most ELM327 series OBD adapters, the App has a simple and easy-to-understand interface, which is easy for beginners to use, realizing vehicle self-inspection and maintenance management easily, making driving more reassuring.
