I have been having an issue with my car for the past week or so. It started one night at work. When I went to leave work one night I got in the car and it said security event occurred. My first thought was great someone was messing with my car( this was my first night at this location and it is in a bad part of town), but then it happened the next night, and then on the 4th of july while visiting my dad it happened twice and no one was even close to it. Then last night it went off around 130am in my apartment complex... so needless to say I'm sure I made the neighborhood happy.
Has anyone else had a similar problem? Is there any code that can be pulled to tell me what exactly is setting it off? Can it be done with any of the SCT tuners or any tuner for that matter?
Thanks in advance!

Thanks guys for the quick responses... JCON I am sorry I do not know what the SJB is lol... as for the passenger side over the winter I had an issue with a drain plug under the windshield wipers where it got clogged and the defroster was sucking in water and dumping it in the floor board... It happened one time once I saw it happen I quickly fixed it to avoid any issues... never had any issues after that
Check the sensor under the hood - passenger side near the shock tower, looks like a plunger. That sensor sees the most weather and will go bad. Once it goes it trips the alarm because it reads the hood open.
When you hit the lock button does your car sound the horn twice? That means it is reading a sensor as open.
When I click the lock button once it locks my doors and then when I hit it a second time the horn sounds once ... does anyone know if a place like auto zone can pull the code and tell me what sensor is tripping it?
Don't know if they can pull the code but check your floor mats again. We've had a lot of rain on the east coast lately. I think the SJB has related components to the security system. If you have water there, it may cause a trip when shorting.
Autozone probably can't get the code for you. The dealer couldn't pull the correct code on mine and they were convinced it was the interior sensor and replaced that. Next day - alarm kept going off again just sitting in the parking lot at work. Called them and had them take another look and they decided it had to be the hood sensor - replaced that and no problems after that.
I don't think it is the SJB - the hood sensor is the most likely cause when it goes off like that with no one around and just sitting there. Mine would chirp once at time too - other times I'd get the double chirp so I knew it was already reading an open sensor. Like I said that sensor is only about $35 plus quick and easy to replace and much cheaper than the SJB. Everything you described sounds like that sensor.
