Blind spot warning constant beeping

Hello, sorry to say there's some kind of camera or radar system that identifies vehicles in the "blind spot", and apparently something is wrong in that system. You will need to have some testing performed to find out what's going on. Testing will require a diagnostic tool to monitor component operation to see what is happening. If the problem is actively occurring, it may make it easier to drill down to the root cause of the concern.
