I have an 04 TL. Small system and auto start. Recently my alarm system has been triggering off for no apparent reason. The other day i woke up to all my windows being open including my sunroof. I have not messed with any electronics recently so im not sure what could be the all of a sudden cause of this. If anyone has any ideas let me know.

 

maybe a intermitent short. if your alarm goes off, its a ground trigger from door open or shock sensor but for windows to go down; i dont know. can you lower your windows with your aftermarket remote?

 

I installed a CompuStar last winter and had so many problem that I had to remove everything and went back to stock. Now I got an appointment with Honda for a "Recommanded" Starter system and it will be guarantied by honda....

My CompuStar was installed by professionals and still had many problems, I guess the TL is a little hard to understand in terms of electronics and aftermarket starter....

that was my 2 cents!
