Strange Beeping After Turning Ignition Off

Bluesman · January 21, 2012

Just started today.

As soon as the ignition is turned off you get three beeps two short one longer, twice over then one long beep.

No warning lights showing.

Any ideas?

Don't know about '98 models the only time mine beeps like that is if the sun roof is not shut...

Is it the stereo system beeping?

I dont think so but will try and locate where the sound is coming from.

Thanks Mike

Well we still have the beeping.

It seems not to be coming from the stereo but from deep within the dash.

It does seem to have changed to 3 beeps 3 times over.

I have checked sunroof and all the other suggestions but they are all ok.

Still no warning lights showing.

I am at a loss as to explain it.

are you sure its inside the car, i had a similar problem on a car i had and it was the Battery at fault in the power sounder for alarm.

A lorry has reversed under your bonnet and you haven't noticed!

Have you tried disconnecting the Battery for a few minutes to see if it goes away? Just make sure you have the radio security code and master key to hand before doing so.

Good point I seem to remember this problem being mentioned before, apparently the Battery is a solder in type but can be replaced if you have the electronic skills required.

Whats going on with these forums? I've managed to post more double posts and muddle up more quotes in the last week than I've done in 6 years!

Had a look but couldnt find anything like a lorry under the bonnet, there was a shiny thing which had NASA printed on it and it made everything around it glow green so I threw it away and the green glow stopped but the car seems to go an awful lot faster. I could have sworn I saw stars on a trip the other day.

She is going in for a service next week so I will ask the garage to check the Battery terminals.

Thanks for all your suggestions.

Well she had her service with just Oil change Filter etc.

My garage (non Lexus) checked her over for any Battery connection problems and everything is 100% OK.

So not only are the beeps a mystery the completely dead Battery of some weeks back also remains a mystery and if there was a dodgy Battery it would certainly have gone down in the freezing conditions of the last week or so.

So if you have any other ideas as to what it might be it would be very helpful.

Have emailed Lexus direct to ask them.

Without sounding patronising would open and close the the sunroof both way i.e sliding and tilt to ENSURE its fully closed and not triggering the alarm. In the past there has been instances where the sunroof is very minutley open and this has triggered the alarm.

Well done Mark I think you may have solved it as the alarm started going off at random last night, so Instead of keeping the neighbours awake last night I just locked her with the door key,

I have just tried the sunroof, fully open/closed and tilit several times but it hasnt cleared the beeping. To cold to sit out there today to sort so will try again once temp comes above freezing.

Any idea where the actual sensors are fitted?

Thanks for all the replies.
