About products and suppliers

Whether you are a mechanic or a supplier of the latest vehicles with onboard computers and driver assist features, at one point, you need a launch X431. Launch scan tools are manufactured by Launch in China and the USA to diagnose a vehicle’s system and generate a health report within a few minutes. The launch scanners also calibrate the vehicle and offer OEM-level services.

How does a launch diagnostic tool work?

To work, the launch x431 connects to a standardized ODB2 port on the driver’s side of the dashboard. The scanner will automatically connect to the car’s computer or engine control module (ECM). With the ignition on, the launch car scanner will thoroughly go through the ECM’s codes and correct erroneous codes or customize features. It will also monitor the engine sensors and share real-time data. The mechanic will then read the findings via a small screen.

Types of launch scanners

There are wireless and wired x431s. Wired or handheld scanners perform all duties in the scanner itself. The handheld x431 scan tool is comprehensive and identifies many problems. Unfortunately, it is one of the most expensive launch scan tools, and its software is not updatable. It is also not practical for hobbyists. The next type is the wireless scanner which is a cheap and small scanner that connects to Windows, Android, and iOS devices through Bluetooth or Wi-Fi. Just plug the small flash-disk-sized scanner ODB2 port and connect to the computer or smartphone. The only downside is the scanner requires x431 apps to offer all-rounded services. In some instances, customers might be required to download several apps.
