Theft light on the dash will not shut off!!!!

[Blood on Blood]

Well, the temp. outside is below zero and the stock "Theft" light came On, which is located on the dash. No blinking, just On.

The Mach 1 locks, unlock and starts. When the key is turned in the ignition and the Mach 1 is started, the "Theft" light turns Off. However, upon removing the key from the ignition, after a few seconds, the "Theft" light comes back on and stays luminated.

Any ideas on how to resolve this issue?

Thanks

Fired up the car and drove it for about 45 minutes. Runs okay, but now the "Theft" light flickers at a high rate of speed when the car is off.

If this continues, then I will take it in. Heck, the weather is cold and it is a Ford, so that means the issue will probably work itself out....

Try disconnecting the battery for a while to reset the computer. If that doesn't work, see if you can pull a trouble code out of the computer with a code reader.

You car obviously has special powers and can see the future. Its probably trying to tell you that someone has been scoping it out and is planning on stealing it. You'd better keep an eye on that special mach. If anyone found out that it had special powers like Kit from nightrider, it would be worth millions. I say let it speak. Maybe the service engine soon light means you are not giving it enough love and attention. Better get on that.

PS: clear out the computer by disconnecting the neg. battery terminal and it should shut up. Otherwise, take it to the doctor.

:cool2:

Do a search on google for PATS. Also try Mfords, and maybe SVTP. Their is a ton of information out their. PATS 1 started in 1996 and PATS 2 sometime in '99. I never messed with PATS stuff before. It is a pretty good system and ive never ran into problems with any customer's cars. I have worked on a TON of crappy Pass key 1 & 2 systems...What a peice of junk..............

ive seen some issues with pats on mustangs ive worked on in the past best bet is to see what code was set in the pats system and check the system over i have seen many mustangs have wires with bad conections shorts and breaks in the pats wires coming from the ignition switch mostly at the end of the tilt wheel

Buy a battery tender.

I think PATS is tied into the instrument cluster. They may need to swap out the whole cluster. May be better to just figure out a way to bypass or just remove the light bulb.

The bulbs can not be removed in the instrument cluster.
The PATS system can be disabled in the tune, if you need to though. I don't recommend it, but it can be done.

I would start checking for loose wires/connections.
The PATS system is made up of 3 components: the dash, the key and the PCM. Any of them can cause the system to fail.

Good luck on this one.

Mine was on this morning when I went to start the car. It shut off once it started and it was off when I got to work.

If you guy have chips, check your connection.

I was once 200 miles from home and my car suddenly wouldnt start,and had the anti-theft light on. I tried everything I could think of, then before I called the tow truck I looked at the Computer just to see and sure enough the chip was loose.

The whole issue started with the cold weather on Saturday. If it continues, I will take a ride to the dealership and have them take a look.

Thank you all for your input.

Same with me. The light hasn't come back on since this morning, so we'll see what tomorrow brings. My car does not have a chip, but it does have a diablosport predator tune.

I guess its just a Mach thing! lol

Stop stealing cars....

Stop stealing cars....

Fine! Gosh, your just so unreasonable!

I see this all the time I work for a ford dealership its usually when the battery is weak in amps. try this when you go to start your car put the key in the drivers side key hole and turn it once or twice that should work.

Will do...

Thanks
