When I start my '01 F-150, the dash airbag light blinks a 4-7 code and then stays on. Can anyone tell me what the code means?
Thanks

 

I did a search, did not find 4-7 or 47 in prior threads, can you confirm thats the flashed sequence?

 

LFC 47 is a valid code if the truck was built after 10/2/00. Check your door label.

Fault code description is "Passenger Pre-tensioner Circuit Resistance High "

Safe the system by disconnecting the battery's negative cable.

The Restraints Control Module is behind the panel for the center instrument panel. Disconnect each connector and inspect for damaged pins. Re-seat the connection. Re-arm the system and see if the fault has cleared.

Loose connections at the RCM seem to be a common reason for pre-tensioner faults.

 

found a connector under passenger seat disconnected, need to keep things out from under the seat
