Hi!
I hope I'm not giving you any incorrect information about your engine, but in my case, I can see how the cruise control is functioning in the measurement blocks, specifically group 6, field 4

.
0 = Cruise control off; 1 = Cruise control on; 255 = No cruise control coded.
The encoding process is likely to proceed as follows:
01 for engine control unit.
11 for login procedure.
Login code: 11463
That's it.
Deactivation code GRA: 16167
Good luck and have fun!
