Airbag light on 2008 Expedition XLT

[Rob Adams]

I recently bought this truck from an auction and have been driving it around w/out issue for several days now. Last night the Airbag light came on solid and when I plug my bluetooth OBDII reader with TORQUE into the truck it's stating it has a B2293 Body code which based on some googling looks like airbag sensor failure? Torque doesn't give me a 19 or 21 designation on the code and the light doesn't flash (solid on)

B2293 19 Restraint System – Air Bag Status (Driver Front Air Bag Circuit Failure)
B2293 21 Restraint System – Air Bag Status (Passenger Front Air Bag Circuit Failure)

Troubleshooting so far:
Disconnect battery (was replaced in november) and let set for an hour
disconnected and cleaned impact sensor under truck No visible wire breakage detected or corrosion on sensor
disconnected and cleaned all terminals under seats (driver and passenger) No visible wire breakage detected
Reconnected battery and started car. Light came back on solid

Short of pulling the airbag itself out of the steering wheel or passenger side any thoughts on anything else I could troubleshoot? I'm kinda worried about driving it as from what I understand the airbags aren't operational at this point.

Aren't there more sensors than that?

I think my Excursion has at least one in front core support area and one in each front door.

I remember having a code for driver door or driver side crash sensor that made light stay on.

Yes I believe there are 3...but the code I pulled was "air bag status" either driver or passenger circuit failure...I checked the impact sensor just for good measure

It would help you to get a reader that can give you the code. A common failure is the seat belt switch and the plugs under the seats. Without being able to see the proper codes, how can you possibly troubleshoot this thing without throwing parts at it?

I have the code its B2293 but does't have a flash code that accompanies it. Everything I've been reading says it should have a flashing code along with it. The light however comes on solid the moment i turn the key on and doesn't flash at all.

I downloaded FORSCAN and got a little better code of B2293-E0...not sure if that helps anybody help me narrow this down

Mine flashed on dash

Yeah that's the thing that's frustrating...I thought I should get some sort of flashing but I'm not.

 

[TobyU]

Does the light come on at all??

Yep comes on solid the moment I crank the motor and stays solid

 

[TobyU]

Ok. at least the light bulb is good. They will ding 5 times 5 times in a row every 30 minutes if not.

 

[Rob Adams]

So here is what FORSCAN is reporting from the RCM...the continuously stored code is the B2293-E0

Here are the pinpoint troubleshooting guides from Ford. You'll need to read a better code though I believe.

I just ordered up a USB OBD2 reader that I can hook up to the full PC version of FORSCAN and hopefully that'll give me something more. I'll probably de-power the whole shebang again tonight and check the connections in the RCM and airbags and clockspring

Such a PITA this is...otherwise the truck is great...

Well I may have found my problem I pulled the airbag and found this pinched wire behind it and I can see bare copper so I guess I'm going to be stripping back to the casing and seeing if I can splice it

You're lucky that thing hasn't blown up in your face. Be super careful.

 

[Trainmaster]

Looks like your problem.

Isn't that the harness for steering wheel buttons?

It may have been actually. I repaired the wires and the lights remain on. I wasn't about to leave it like that regardless. Not sure if there was any sort of sensor wires also tied into the airbag. I'm beginning to think the airbag itself may be bad. Still waiting on my USB reader to hook up into the PC version of FORSCAN to see if I can pull any other details on the code. Should be here saturday.

Does anybody know what the OHMS reading for the DriverSide Airbag is? I noticed something in my mobile forscan app..

Pass Airbag reads 2 ohms
Driver Airbag reads 26 ohms

that seems WAY off...this kinda supports my theory that the airbag is bad?
