Help! Beep...

[aeroelastic]

Hi,

As soon as I turned the ignition on, there are 2 distinct beeping noises.

One beep is like the parking sensor but the other is a lower tone beep.

No warning light on the dashboard, No light turn on, footbrake off.... The beeps keep going during driving.

Anyone has any idea?

Thanks in advance.

Could it be that the tailgate is not properly closed? (although I think this would show on the dashboard display)

I assume you wear your seatbelt?

[aeroelastic]

Seat belt on..

Tailgate closed.

I suspect the door lock sensor, anyone know where this is?

[DanD]

hmmm... like the open tailgate, would it not show on the dashboard display?

[DanD]

Just thought... you say seat belt on, but it could be related to the sensor in one of the seats.

Either in the driver's seat: you're in the seat, and have your seat belt on, but this does not get picked up by the sensor OR

Passenger's seat: no-one is sitting there, but the sensor within the seat thinks there is and is asking the non existing passenger to belt up.

From looking at my own car, the sensors in the seat are at the back for the sitting area. You can see 2 raised spots under the leather, in front of the back rest.

You haven't put a heavy-ish back on the passenger seat by any change, have you?

Thanks, will check the sensor.

But the beeps sound more like the parking sensor beep rather than the seat belt beep.

Have you put anything heavy on the seats which might fool the sensor into believing someone to be sat on one without wearing the seat belt?

[aeroelastic]

After listening properly again, I am quite sure its not the seat belt beep, this is much higher pitch.

It is very similar to the parking sensor beep but slightly higher pitch.

It happens randomly but very often during driving...

Can anyone recall what beep this will be?

Does RX300 2004 have tyre pressure sensors?

Can this beeps be scanned by an OBD2 code reader?

All,

Does your car have this switch???

What is it?

I pressed it and the beep disappeared!! But the rear parking sensor stops working.

Any idea??

[aeroelastic]

I think this is to turn off the rear sensor when towing..

So something must be wrong with the rear sensor, i changed a tyre last week, probably I have disturbed the wiring,,,

Anyone repair the rear sensor before??

[aeroelastic]

Hi,

Use the car at the weekend, the rear sensor actually still works.

What is that switch then?? Sorry lost my car manual..

Can anyone help?

[vadre]

Do you have front sensors?

I have a similar switch to isolate my front sensors but its in a different place. Dealer fit I believe.

I rarely turn them on so it has caught me out when I have left it on.

[aeroelastic]

Thanks...

Whicever way I switch it, the front and rear sensors still work, maybe something is wrong.

I noticed that one of the front sensors is pressed in slightly, can I just cut the wire and replace one rather then replacing all?
