Thdft light on
2002. Ford expedition won't start theft light
is on . Also can't find a reset button either.
Can you help me?
You won't find a reset button cause there isn't one for the security system. So try this: from the inside manually lock all the doors except the drivers, then with key in hand exit the vehicle close and using the key manually lock the drivers door, watch the dome light and when it goes out wait at least one minute, then using the key unlock the drivers door, enter the vehicle and attempt to start the engine, if everything is in operational condition it should start and run, if not then there is a failure in the security system and it will have to be checked out by someone who knows this system, most common failures are the inter door latch switches, but they will have to find out how many went bad.
