First of all, I apologize for posting this here, because what I'm dealing with is the factory car alarm system. Not exactly custom.

Anyway, my problem is yesterday, I got a flat tire, and got out the spare and changed it, etc. I had to unplug the wire for the speaker on that side that's set in the plastic faring, and set it aside. Well, when I went to get the tire repaired, for some reason, the mechanic, when putting my spare tire back into place, unplugged, then plugged back in the shock sensor that's mounted under there as well right on the wheel well. So, I saw the guy plug it back in, plug the speaker in, and pack everything back in and close it up.

I got in and left, and then drove home. When I got home, I got out and pressed the lock button of my key fob, and heard the two quick horn honks that signal the alarm is now armed.

Ten seconds later, the alarm started going off. I hit unlock, then lock. Again, the arming sound, and ten seconds later, alarm goes off again.

Now, incredibly enough, a call to my local GM dealer got me a response of we don't know what's wrong with it!

I mentioned that I'd heard that possibly the computer needs to be "reset" or whatever using the radio (I have the stock factory CD player) and the guy said he'd never heard of this before!!!

So, have any of you got any idea how to fix this issue? Right now I have that shock sensor unplugged, but obviously that's not a practical long term solution.

 

i believe the shock sensor is adjustable, you might look into that for your answer...
