How to check the models and functions supported by the Launch diagnostic tool without the Launch X431 tool on hand? In fact, Launch has a webpage that can be used to complete this requirement. This article will introduce how to use the Launch online query function.
Launch X431 Vehicle Coverage Query: [https://qcar.x431.com/qcar/]
Take LAUNCH X431 PRO3S+ to diagnose 2022 Audi A7L as an example. We first need to select the region of the LAUNCH device on the website (for example, PRO3S+ is a product sold in an online store), then select the type of LAUNCH device (for example, PRO3S+ is a professional diagnostic device), and finally Select the car brand Audi that requires diagnosis.
After entering the function page of the Audi software, we can select the Audi vehicle model and the functions we want to test. We want to check the LAUNCH tool’s support list for the 2022 Audi A7L, then we should select the Audi brand, A7L model, and 2022 year in order Production; finally fill in the functions you want to perform.
