The Launch X431 SmartLink C HD LITE cannot operate as a complete standalone diagnostic scanner. A compatible Launch X431 8-inch tablet is required.
Software update terms can vary by package and region, so the included update period should be confirmed before purchase.
Why Choose Launch X431 SmartLink C HD LITE?
The Launch X431 SmartLink C HD LITE is an efficient way to transform a compatible 8-inch Launch X431 PRO-series scanner into a professional commercial and heavy-duty diagnostic platform.
With 75+ commercial diagnostic software packages, full-system diagnostics, live data, supported bi-directional tests, special functions and extensive truck/engine coverage, it significantly expands the capabilities of an existing Launch diagnostic setup.
The combination of SmartLink V2 hardware, dedicated heavy-duty adapters and commercial diagnostic software makes it particularly suitable for mixed-fleet workshops that service both passenger vehicles and trucks, buses, trailers and commercial electronic systems.
