I have a 2003 X 7.3 and when i get in the truck and put the key in the airbag light blinks 3 times then 2 times 3 times then 2 times 3 times then 2 times then stays on solid. I have seen in older models that this can indicate the airbag clockspring but this part is not available on the 2002-2005 X there is an airbag control that looks similar to the clockspring and it is $106 at the dealer. What is the likely cause of this light sequence and what is the part number for the replacement part?
