Theft light stays on

I have a 2000 Mustang and just recently I noticed that when I turn my car off the theft light either stays on or blinks at roughly a 2 second interval and does not blink rapidly as is the norm. However the my car starts and runs fine. I have tried reprogramming the ECU as well as disconnecting the battery to reset the ECU each of which did not fix the problem. Has anyone else experienced this problem? Possible causes? Any ideas how to fix this aside from taking it the the Ford dealer?

Yeah it's definitely odd seeing as no DTCs register either. Suppose I'll just give it some time.

That's interesting. I'll give it a shot but my battery is fairly new and according to the volt meter it's putting out a little over 12 volts.

Do you have the chipped key? Because without it you wouldn't be able to start the car. Maybe someone changed the ignition on it and disabled the theft system to do so. A DIY ignition change


This is the chipped key that comes with our cars

Damn did you try eating it or something? Lol but yeah, as long as the chip is connected to the key there's no problem. But once the actual chip is broken then your car won't start

Yeah I have the chipped key and am the original owner of the car. Only "ignition" work I have done is change the spark plugs and wires a year or so ago so any other DIY ignition work is news to me lol.

Then I'm stumped maybe it's Ford wanting you to come back to the dealership to have their way with your wallet?

Ha yeahhh honestly wouldn't be that surprised. But who knows, it's probably somehow related to the new wheels and tires I just got lol. That said Nitto NT555s are epically amazing.

Yeah they are like skating on a glass surface of pure grip. Love them!!! I think I'm gonna pick up an aluminum drive shaft next myself.

Did you mess with the overhead light console or stereo lately?

I remember that one time I had pulled the overhead cabin light fixture.... And when the motion detector sensor wasn't hooked up, the anti theft lights went crazy... But I was able to start and drive the car.

Not sure if your year has that or not. If it does, maybe a short to some sensors?

Nope haven't done any work along those lines. I imagine it is a dying sensor issue though. It does not seem to be problematic yet I just don't want to find my car immobilized one day when the PATS system does finally decide to go ape sh*t.

Without the chip the car starts, but shuts off after 2 seconds. I lost my key once and had to use a backup key with no chip in it. It takes a long time to move a car up the driveway with it running for 2 seconds at a time......

Did you try putting it in neutral instead? I mean I don't think it's that heavy. I tried pushing my 66 up my driveway and I to the garage by myself and it wasn't too bad

Had time on my hands, and curiosity got the best of me.
