Air Bag flashes 1 - 9 - solid
Hi,
I have been looking through posts on flashing airbag lights as my airbag light is flashing 1 then 9 a couple of times, then solid on. (2004 Expedition).
I'm a bit of a novice and can't see where you find the codes or what I need to do. My nearest dealer is about 4000 miles away so I'm a bit stuck.
Any help welcome.
Thanks
Mike

For the 04 Expy, a LFC code means the RCM has detected a circuit fault with the driver's side airbag module.
The following cut and pastes from the workshop manual may be helpful:
Pinpoint Test H: LFC 19 and 21 /DTC B2293 — Restraint System - Airbag Status
Before doing ANYTHING with the airbag system, disconnect the battery and wait for at least a minute.
I've seen a few conversations in which the owner was able to find pushed out connector pins at the RCM connector. The location of the RCM depends on the front seat configuration of your Expy. It you have the 60/40 bench, you have to remove the 60 seat to get to the connectors. If you have the center console, you have to remove the console.
If you decide to mess with this yourself, you should get the factory service manual procedure. Failure to follow critical safety instructions contained therein can place you at risk of great injury.

Pinpoint Test H: LFC 19 and 21 /DTC B2293 — Restraint System - Airbag Status
Normal Operation
The restraints control module (RCM) checks all of the front air bag circuits for faults. If the RCM detects one of the following faults on any of the front air bag circuits, it will store diagnostic trouble code (DTC) B2293 in memory, and depending on the fault, flash either lamp fault code (LFC) 19 or 21 depending on the fault (or higher priority code if one exists) on the air bag indicator.
Fault Conditions
The RCM monitors for the following fault conditions:
low resistance.
circuit open.
circuit short to voltage.
circuit short to ground.
Possible Causes
A driver air bag status fault can be caused by:
damaged wiring, terminals or connectors.
driver air bag sub-harness.
a faulty clockspring.
a faulty driver air bag module.
a faulted RCM.
A passenger air bag status fault can be caused by:
damaged wiring, terminals or connectors.
a faulty passenger air bag module.
a faulted RCM.
