Help! A beep Followed by 5 min buzzer.
Hello, I’m new to the group.
I have a 2018 Rav4 LE AWD. It’s maintained pretty well. Parked in a garage at home, no lights on the dash, no issues while driving.
I recently went on vacation for a week and came home, drove home with no issues. Next day I go to get groceries and when I started the car there was a beep I’ve never heard before. It was one beep that went away then after about 15-20 seconds there was an audible long beep/buzzer that was continuous for about 5 minutes then turns off. Loud enough to be very irritating. The sound comes from the dash. When I turn the car off while the buzzer is going it will continue. It would turn off if I open the door with the car off. If the car is on I can’t stop the buzzer by opening the door. I don’t know what it is because there’s no lights on the dash and there’s no codes from the reader.
I researched that the sound could be from a dying battery. I got a new battery and the buzzer persists. I read it could be the antitheft and to reset the system by taking the positive terminal off for 15 min. I did that. I checked all the doors to make sure they’re closed including the back hatch. If a door was open then it would show on the dash but did it anyway. I checked the seatbelts and the seatbelt alarm by driving with no seatbelt and buckling up to stop the alarm, everything was working there.
Everything is stock. No aftermarket parts that would be making that sound.
I’m checking to see if anyone in the group would have an idea before bringing it into Toyota for service. I’m pretty handy when it comes to doing things by myself but I’m clueless as to what is causing this. please help if you can. Appreciations in advance.
Edit: Also checked the fuses. Fuses look fine.
problem: A gps tracker was installed from the previous owner. The gps was located behind the mirror and lane departure control panel. Took out the gps and buzzer. Problem solved!
