That means the factory security is not arming, not being set. ( i.e. a door is not completely closed or the trunk/door lock has been vandalized ) It could be for other reasons but first check the obvious

SOURCE: Rear defrost not working on 2000 legacy gt, fuses

If it is a wagon the wiring goes bad back at the gate. If not you need to check the voltage on both sides of the grid and work back till voltage is found.

2000 taurus left turn signal flashes rapidly and the left rear turn signal lamp does not work. Does ford have burned out bulb sense circuit that would give this indication? The right side flashes normally.

Yes - the fast flashing is a warning that a bulb is burned out. Change the bulb (be careful to put it in the same as the old one as it probably is 2 bulbs in one , parking and turn/stop) and you should be fine.

Turn your key to the "on" position. Your security light will be flashing. Leave it in the on position and wait for 10 minutes. The security light will stop flashing, and it will reset itself. Turn the key back to the off position before trying to start it again.
