Default Long nonstop beep noise

I been having problems with my 02 Sc430 I took my seats out to clean the floors and put them back in and started my car. I then noticed a continuous beep noise that won't go away until I turn off the car completely any help would be great

Think you need to tell us more...any dash lights? Roof closed? Passenger seat occupied? Seat belts fastened, both? Trunk lid or door ajar? Source of the sound? Sounds that you’ve heard before or new? Can you record and post ?

Yep...the long continuous tone the the ABS warning.

There are a number of potential problems. You’ll need to get DTC from the OBDII PORT. But it may be just one wheel speed sensor going bad. It would trigger the ABS light, and the "Brake" light may be just a generic warning for anything brake related that comes on automatically if the ABs light comes on. Due to the Abs problem, the ABS system shuts itself off completely, leaving you with normal non-abs brakes. Because the ABS unit is shut down, the stability control (VSC) cannot work, so it shuts off and turns a warning light off. Same thing for traction control in vehicles that have it. They all rely on ABS sensor signals to work.

So today I checked 3 sensors and they all were between 1500 to 1700 ohms but I realized that my back right sensor was nowhere to be found and that I couldnt test it everything seems to be fine my back left was in plane sight but my back right was back up somewhere and didn't get to it. so I check all my fuses and I changes the abs 7.5 fuse with another 7.5 fuse and the continuous beep goes away and also the abs and brake light go away but come back on after 1-10 seconds, could be a bad ground somewhere, could that be what is wrong(the sensor I didn't test could be what's wrong I sense)

My 06 beeps when moving the seat backwards. I guess to potentially warn a rear occupant. Maybe this is the sounds you are hearing?

Edit, never mind. With the abs system activated that makes sense.
