I successfully completed the work in Colorado with OBDSTAR Odo Master, here is the operation path:

Mileage -> Americas -> GM -> GM V31.11 -> Chevrolet -> Colorado -> 2018 – > odometer recalibration -> This function is available by connecting the server, please ensure the internet connection is normal.

Alright, the next operation is to follow the on-screen guide.
