Launch X431 SmartLink B – Remote Diagnostic Device

The Launch X431 SmartLink B is a remote vehicle diagnostic interface designed to let professional technicians perform advanced remote and local diagnostics on cars through a cloud‑based platform. Rather than just connecting a diagnostic tool directly to a vehicle locally, it enables a technician — even at a distance — to access vehicle data if paired with the required SmartLink C dongle on site.
