@csouers want to take a stab at this/test on any cars you have access to?

Here's what I got from my own car. Some of the responses with the --nonstandard flag look to have what might be hardware part number data, but aside from that, nothing interesting like a response from a new module. Some part of the query process did cause faults to show on the headunit. I didn't investigate into the root cause of that.

I did have to disable some checks (against unexpected responses) in the uds library in order to complete the query. I used the query script in panda/examples for this.

can 1 in normal mode: https://gist.github.com/csouers/bb6abba0658609484f29572070190ca4

can 1 in obd2 mode: https://gist.github.com/csouers/7dc1d0227c1024de6744c409d4213a6d

The private can (bus 0 and 2) between the camera and radar yielded no responses whatsoever.
