Description
### Describe the bug
This appears to be exactly the same as commaai/openpilot#25525 but on a 2024 CX-5 Signature. Copying and pasting that report as it's still exactly accurate:
> When driving with OP active, front camera sensor error shows up on the OEM instrument cluster
>
> similar error to https://vf.vin/static/uploads/images/sr2/mazda/2022/02/18/2018-mazda-cx-5-jm3kfbdm5j0335098-img-13.jpg
>
> Error goes away with disengage/rengage OP
>
> No errors seen on C3 unit and self drive does not disengage and does not seem affected
The rest of the filer's description is accurate too.
I have tried on:
* Stock OP 0.9.5
* A custom version of 0.9.5 I made with @Jafaral's [mazda-tja](https://github.com/Jafaral/openpilot/tree/mazda-tja) commits rebased onto it: https://github.com/DouglasSherk/openpilot/tree/mazda-tja
### Which car does this affect?
2024 Mazda CX-5 Signature
### Provide a route where the issue occurs
60ed2cf2b490292c|2023-11-21--17-47-15--12
### openpilot version
0.9.5
### Additional info
I noted that:
> The lane lines are no longer present on the lane-keeping assist dashboard, so I'm guessing it has something to do with that. When I unplug the C3 but keep the harness in-place, everything goes back to working stock, so it's not a problem with the wiring.
@Jafaral suggested the following:
> Lane lines going away is just a result of the camera error, and not the cause of it., most of the info you see on the dashboard are just decorations really.
> CAN data might reveal more info
Hence I collected the route and filed this report.
I don't think trims lower than Signature have Traffic Jam Assist, which appears to be the source of the problem. That might be why no one else with a 2022-2024 CX-5 has experienced this issue.
I'm a total newbie at OP, but a competent developer otherwise if that's helpful.

Research direction
Start by examining route 60ed2cf2b490292c|2023-11-21--17-47-15--12 and the CAN data collected for the 2024 CX-5 Signature. Compare the behavior with commaai/openpilot#25525 and the mazda-tja changes, then determine which signal or integration causes the OEM camera error. Done means the cause is identified and the failure is reproducibly resolved without affecting self-drive.
