Let me do the easy part first. Check to see if you even have a side air bag. More than a few people here ( my self included ) have had an air bag code about the side air bag when I / we don't even have side air bags.
You should see a pig tail under the seat with a bright yellow connector. If it goes to nothing, obviously you don't have side bags. Disconnect the batery, wait about ten to fifteen min. Pop the cover off the end of the pig tail. ( push the button on the connector ) blow in there a few times get the dust out, put the cover back on. Make sure the wire is out of harms way. Not in the seat track or nothiong. I did that and it cleared the code right away. I did not even need my code reader.
I am 99% sure Ford clock springs run the whole 9 yards.
Check your horn and cruse control. If they work your clock spring is fine. It still may not be connected to the bag itself. Again disconnect the battery, wait aboutn fifteen min. Behind the steering wheel are two little caps. Pop then out with a tiny flat head screwdriver or knife. There should be two 8mm bolts behind there.
Pop them out and the air bag should come out.
You will see a wire again with a bright yellow connector
( yes it is a standardised thing. All cars after a certian year all SRS wire conncetors must have a bright yellow connector ) See if it is connected. Note that it can only go on one way and one way only. Study it first for signs of damage or menting. A lot of times that connector just melts to noting after an air bag deployment.
Re connect it if all looks well, reinstall the bag. Connect the battery. When you get in to check your code slide the seat all the way back incase that sucker goes off.
It is unlikely that it will but it is some what possible.
turn the key to run but do not start. Watch the light do its test. If it goes out, well jack pot. If not let me know and we will see what is next.
Let me know if I can help any more.
