Looks like you have the wrong harness, the messages exist on bus 2 (camera side):

Which harness did you buy? Can you take photos of your harness and post, or reference this? https://github.com/commaai/openpilot/wiki/Hyundai-Kia-Genesis

openpilot reports everything is fine with that route if we flip the buses in the logs, so I recommend trying to flip the CAN bus on the harness. There should be users in Discord to help with that, or you can view the wiring diagram for your harness in the above link. You just take certain wires out and flip them.

When I haven't connected to C3X yet, everything is normal, indicating that the wiring harness should be fine，The model I am using is Hyundai N

Great! Unfortunately we don't have any harness that is the opposite of this, @vanillagorillaa prefers not to add another variant just yet until we see more cars that require this harness. Feel free to check back in the future
