When your Expedition is shut off and securely locked up , the theft light flashes to indicate the alarm system is armed
When the vehicle is shut off and locked up , the flashing theft light shows that the alarm system is armed
If you try to start the car it should start then turn off by itself, just leave the key in the run position and the "Theft System" light on the dash will be flashing. Leave the key on for about 10 minutes and the light will stop flashing and go on solid, then the theft system is disabled.
If the vehicle is locked , a flashing anti theft light means the security system is armed ( on )
If the theft light is on in your vehicle, it usually means there is an issue with the anti-theft system. To turn it off, you may need to reset the system by locking and unlocking the car with the key fob or key. If this doesn't work, you may need to have the system diagnosed and repaired by a professional.
on top of the dash pad near the anti theft light
no
This is just to deter theft. Whether or not your car came with an optional anti-theft system, the light will still be there, simulating a anti-theft system. It's just a light-emitting diode, so it doesn't have enough draw to drain the battery.
advtrac light will not go off
It sould slowly flash when the engine is off.
Try putting the key in the driver's side door and locking and then unlocking it. It works in my 2001!
The security light flashes when a programed key is not installed in the ignition, when you insert a programed immobilizer key in the ignition the security light will go out, the light flashes as a theft deterrent
