Mercedes OBD-II Service $22 PIDs
Sup guys?
I'm a software engineer looking to understand a bit more about how handheld flashers work.
I've sniffed some traffic from a MyGenius and I see the first request sent is:
can0 7E0 [8] 03 22 F1 21 00 00 00 00
Does anybody have a list of service $22 PIDs for Mercedes/know where I can find one? I'm having a hard time figuring out what PID 0xF121 is requesting.

I've read service $22 is SAE J2190 for Ford/GM. Can anybody confirm is service $22 is SAE J2190 for Mercedes? If it isn't, what is it? Is service $22 UDS (Unified Diagnostics Service) in this case? What service does UDS usually live on?
