Bobk528 Posted November 22, 2005 Share Posted November 22, 2005 I always park my 2000 RX300 in my garage and while eating dinner the horn went off even though I never activated the system and nobody was in the garage. Anyone knows how this could have occurred or whether others have experienced a similar situation? Quote Link to comment Share on other sites More sharing options...
SKperformance Posted November 22, 2005 Share Posted November 22, 2005 Could be a bad pin switch on a door or hood or you have a battery issue, does your clock ever reset when starting? Quote Link to comment Share on other sites More sharing options...
Bobk528 Posted November 22, 2005 Author Share Posted November 22, 2005 Could be a bad pin switch on a door or hood or you have a battery issue, does your clock ever reset when starting? ← I checked the battery and the readout window shows a blue light. which is an indication that the battery is fully charged and is okay. You mentioned a door pin switch so I did a search and someone mentioned that the alarm problem is probably the "Drivers Door Power Window Master Switch" and that there is a service bulletin on it. If the alarm sounds off again, I make an appointment with my Lexus service dealer. Thanks for the assistance. Quote Link to comment Share on other sites More sharing options...
