Trying to understand what are readiness codes for certain manufacturers. The codes are 9 in length. The characters are U and S.
Ex. USSSUUUSU
I'm trying to understand what these codes mean. Are they the manufacturer's blue print or does it mean something else?

It's not a vin number because a vin number is 17 characters. This code is 11, not 9, my mistake. Also, it's only 2 letters, U and S. I am attaching a pic below.
Thanks

S = Set, U = Unset

The chart goes with a table that shows in which order the various monitors run and what the drive cycle is to get each item to run. The attached pics shows a couple versions of the 11 monitors.

Most of that is in the factory technical service bulletins or in the FSM for particular vehicles. Some makes simply have a single readiness monitor drive cycle. Some of this you can also find in scan tool "help" sections.

Full versions of the above. Just search and you should find the. Pdf files.
