LAUNCH X431

  Question : I have a LAUNCH X431 PRO5 tool and want to calibrate the ADAS front brake radar of a 2019 Suzuki Swift, but the device indicates that the function execution failed with error code 1337 . I tried accessing the function interface through the ADAS menu and the vehicle software menu, but neither worked. Doesn’t the X431 PRO5 have ADAS functions? How do I perform the calibration?

However, calibrating the vehicle radar is a static calibration and requires an ADAS tool, such as the LAUNCH X431 ADAS Radar 3-in-1 ACC+Doppler+Corner Reflector Calibration Set.
