Car Alarm Help!
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 "Huh, we don't know what's wrong with it! You outta bring it in and we'll run a diagnostic on it" Yeah, because I need to spend seventy or eighty dollars for them to tell me the system has been reset.
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!!! Way to train your mechanics, GM.
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.

Hey Bro,
It sounds like the alarm's -neg trigger wire is touching ground and setting off the alarm. If the problem cleared after removing the shock sensor, then the problem is the shock sensor and needs to be ajusted or replaced.
If not, I would start by checking the area your mechanic was working in, and back-trace the -neg trigger wire that was connected to your shock sensor all the way back to the alarm module. If the wire is touching ground, it’s going to trigger the alarm.
You could also temporally cut that -neg trigger wire (not too short) at the alarm module's brain and see it that clears your problem.
