Velcrometer Posted December 22, 2008 Share Posted December 22, 2008 I suddenly have an aggressive sounding alarm beeping every time I turn the ignition OFF (1990 LS400). This is NOT the same beep sound as when a door is ajar, or the trunk is open, etc... It's more like an alarm clock, three or four loud beeps together repeated a few times, then it stops. No lights are on the dash panel or anywhere else indicating what it is. Clearly it's alerting me to something, but what? Maybe it's the sound one hears right before the bomb goes off :P Quote Link to comment Share on other sites More sharing options...

Velcrometer Posted December 22, 2008 Author Share Posted December 22, 2008 I can't get the key out fast enough before this alarm starts & it keeps going even after the key's out. Anyone else? I can't be the only person who's ever had this happen, can I? Quote Link to comment Share on other sites More sharing options...

jschmidt Posted December 23, 2008 Share Posted December 23, 2008 Yes, sounds like the sunroof 'open/ajar' alarm. Quote Link to comment Share on other sites More sharing options...
IS400 Posted December 23, 2008 Share Posted December 23, 2008 Yes, sounds like the sunroof 'open/ajar' alarm. Yup. It goes off if the sunroof is tilted back. Not if it is pulled back straight into the roof. My opinion is that if it is tilted back someone could just rip it off the roof and get in the car easily and warning you that it could be stolen easier? Who knows.

Velcrometer Posted December 23, 2008 Author Share Posted December 23, 2008 YOU GUYS ROCK!!! Invisible from the outside, so I didn't bother to check it. It wasn't open at all, no leaks even in the last couple days of heavy rain here. But, I remember reaching up to turn on one of the interior lights & I must have just barely touched the tilt button for a nano-second. Just enough for the computer to trigger the alarm. Thanks so much for your expertise guys! :D Quote Link to comment Share on other sites More sharing options...
