Air bag light

[Harleigh]

Hey guys new to the forums. 

I was hoping i could be helped out with a little problem im having with my 2009 ford fiesta style. i brought the car as a spare or repair. iv had a air bag light on since iv owned the car, i took it to a friend of mine down at JVS he told me my RCM needed to be reprogrammed so off to ford i went they manged to reprogram my air bag module however the light is still on they told me my front crash sensor was in the wrong position so we got a new sensor ordered in and replaced it however iv still got the light on. at this point i was like how! so i got a DTC scanner hooked it up and got the error code for a front central restraint and car configuration parameters. 

does anyone know why i keep getting error codes thrown up or is it one thing thats coursing these issues? thanks for any advice
