On an hour drive yesterday, gauge cluster started showing me a brake lt circuit failure. Soon after, lots of other random warning codes flashed. Tire failure, door open, hood open, esd regelt, asc from what l remember off the top of my head.
None of these codes were true. I have an extra CCM, and read that this relay was the issue, so l swapped it out but this didn’t fix the problem. Where should l look next? Gauge cluster, fusebox wiring? Is there another module that can cause this?
Codes do not come on until about 15-30 min of driving. Brake lt circuit is the only one that is persistent after they all flash.

Any ideas appreciated!
