Clone devices may require more specialized interventions.
If the KSuite software cannot properly identify the hardware firmware version, it will gray out options or throw a protocol error.
The target ECU is not supported by Kess V2 via OBD port due to hardware limitations of the tool. kess v2 protocol not found
