Stop command not working on Ver 3.7 with device TK103B (H02 - PROTOCOL)

Hi, i´m using Traccar ver 3.7 and my device is chinese TK103B using protocol 5013. Command to cut and release engine is not working even if i try "DY" , "DY123456" or some one else. DY or TY plus device password works fine. Please can you help me ?

Thanks !

Do you have protocol documentation with commands format?

All i have is the Device user manual and the basic instructins to change apn, ip, admin etc...
Wich works by SMS.

Thanks.

Without documentation I won't be able to help. I don't know the format for commands.

I get this document from web is in chines but i used BING translator and get some informations:
