Here comes the solution.

In the cloning menu, detect gearbox system information.

Check the BOOT version. If the boot version is 401, new boot ver 0401. Bench no works. Yanhua ACDP will not clone this gearbox nor correct mileage.

DQ381 G2 401 bootloader is locked. ACDP cannot do it.

You need other device to unlock 401 bootloder. i.e Autotuner.
