When your Expedition is shut off and securely locked up , the theft light flashes to indicate the alarm system is armed
I had found a loose wire or crimp was bad where there had been a wire lengthen for some reason to my module for the alarm and pwr locks etc.
it could be your transfer case, my need to be rebuilt.
My 2003 ford expedition stalled after the high temp low oil light came on. How can i restart my truck?
WE had the same issue with our truck. Its a sensor in the ignition that you can't change or by pass. Its an electronic chip sensor. It took 6 trips to the dealer to get this found and fixed. Good luck
If your O/D off light is flashing in your gauge cluster that means the powertrain control module has detected a malfunction
the clicking sound is the blinker. when you signal to turn with your blinker the light flashes and makes a clicking sound.
the oil pressure in the engine rises when the truck is warming up causing the light to show, if continues after the truck has been running, change oil and oil pump.
When the engine isn't running and the doors are locked , the theft light should flash on and off indicating that the alarm system is armed
noooooooooooooooooooppppppppppppppppeeeeeeeeeeeee =(
In the truck
"I found my code under the rear of the truck"
To many variables/year/model /auto or standard/describe light thats on/were their any problems leading up to this, or maybe the exhaust brake is stuck on, or maybe you have ignored your regeneration light on a newer model.
