The Launch X431 PRO 3 should support full system diagnostics, including over 31+ special reset functions (e.g., Oil Reset, EPB, SAS, and BMS). For high-end B2B procurement, ensure the device supports Bi-directional Control (Active Tests) and ECU Coding. If your clients service heavy-duty vehicles, check if the unit is compatible with the HDIII module expansion. Furthermore, verify that the software includes FCA AutoAuth access for diagnosing newer Chrysler, Jeep, and Dodge vehicles in the North American market.
