Question about 2002 Ford Explorer

1 Answer

My 2002 Ford Explorer anti-theft system goes off by itself all the time. Checked all doors & locks & seem OK. Doesn't seem to be on its own circuit so that I can pull fuse. How do I permanently turn off/disable it without loosing necessary things like horn, lights, etc.?

    OK I'll give this a try when I can, but why do you think this is happening? Have you seen this before? Is there an easier fix?

  • The factory alarm disarm wire is dark green and purple (negative polarity) in the drivers door harness. Once Located, splice into this wire with a similar gauge wire, and put it to a solid chassis ground. This terminates the OEM alarm functions entirely. If you try to do this any other way you risk the vehicle not even starting.

    Keep in mind that if this does not fix the problem then this is not a factory alarm system and I will need the make and model of the alarm to further assist. If this is Ford Factory then follow the instructions I have posted.

    Good luck,

    • This has been a huge problem with Explorer factory alarms. I have been trying to see if there is a TSB on this. The problem is a window leak on the drivers side window in the real. Then it moves on the the alarm module and sets off the alarm. After a while it really can go off at any time. I will continue. OK I found the TSB which is a Service Bulletin.

    • They suggest to try to reprogram the FOB. Now you can give this a shot but it does not always work which is why I always go right to disarming it. But follow the instructions on the link and if that does not work then try grounding the wire as I first explaind.

    • If your vehicle was under warranty Ford would take care of this. Do you have an extended warranty? If so inquire with them about this TSB.

My 2002 Ford Explorer won't start after a diagnostic test was performed. Mechanic is stating it's due to the anti-theft device system, but they have no idea how to fix it.

How is that possible,they should have a data
base, such as AllData or Mitchell, etc or
they can not work on any product & may as
well close their doors and go out of business

Your owners manual will explain the system as
far as using it

Any repair shop, should have 15 years experience
with an Explorer,there are a million out there

You need to move on to another shop,don't pay that
one anything

1996 Explorer anti-theft system won't disable The anti-theft system on my 1996 Ford Explorer will not not turn-off with any normal method. Electronic keypad unlock on driver's door will not disable,...

Try re-setting the computer...Disconnect the negative terminal of the battery and leave off for 5-10 minutes. This will allow the computer to reset. The charger may have interupted the signal or something.

1994 ford explorer limited anti-theft

Two tips:
* If your anti-theft system is sounding (horn honking/lights flashing)you press the panic button on your key fob to shut it off.

* If your anti-theft system is armed (but not triggered) it is disarmed when you unlock the door(s) using your unlock button on your keyfob, the key pad on the driver's door, or your key.

Hope help with this. Good luck (remember rated this).

Anti theft system for 2002 ford explorer.

take this to the dealer and have them scan the system door ajar switches, one or more is sticking, this is the problem with the alarm most likely as well, the door ajar switches (there are 6 on a 4 door) are twisted into the door latch inside the door without scanning the GEM (generic electronic module, controls locks and windows and wipers) you would have to pull all the door panels and taligate and test a each switch, a very expensive time consuming job.

Anti-theft system

First is this an after market system? If so you will have to find the box under the dash and disconnect it. also if it has starter disable you will have to repair the wires that the installer cut to install that feature. If it is the factory alarm it is behind the dash.
