Hyundai: 2023 Palisade port support

[alancyau]

The 2023 Hyundai Palisade is a mid-cycle refresh and has added CAN-FD. Therefore, a fingerprint update of CAR.PALISADE won't work.

Note that SEL trim with Premium Package and higher adds HDA2. SE and XRT trims retain HDA.

Route Logs:
The Hyundai Harness A was used. It's unclear if the pins need to be swapped based on the updates to the car. Both the stock A and swapped pins logs were uploaded.

Stock Harness A route:
28aa956828c3407d|2022-11-21--22-40-37--0

Swapped pins route:
28aa956828c3407d|2022-11-21--23-04-42--0

Pins swapped per this picture

Once we figure out the proper harness, it appears there's still some CAN decoding to do per @sunnyhaibin

Yep, still the same with the SCC and LKAS11 messages, different definitions to the ones already have now. There's a possibility that the ADAD driving unit can be ignored, but won't know yet.
I'll ask comma and see what's the approach on this, it's gonna be messy and a long process.

Can you explain a little bit what you see and what's different from other Hyundai cars?

Signals don't make sense with the current DBC (hyundai_kia_generic.dbc)

Got it, is there anything else to do in the meantime?

If you are inclined, you could reverse engineer and start understanding what the bits mean in the applicable messages in cabana.
https://connect.comma.ai/, cabana to get started
My project stack is quite full and won't be able to reverse engineer those messages, especially when I don't have access to the actual car 😦
Seems like those messages are the ones to deal with, but won't know until they can be confirmed.
