is this a code 52 blinks 5 times pauses than 2 other times does this a total of 5 times than stays on after that the airbag bell beeps a total of 5 times once then stops beeping when 1st starting

after each start it goes thru 5 blinks a short pauses than 2 blinks than stays on, after that then the the airbag beeps 5 times pauses repeats those 5 beeps totaling 25 beeps before it stops for a while, its does this every time I start it up and every so often while driving for over 20 minutes or so would this code be considered number 52 and how would I go about getting this to stop its a cab and its not good for my customers to keep asking me about whats that beeping sound is it my seat belt. What would happen if I just unhooked every plug under that seat the drivers seat I was told by the ford dealer after paying them $105.00 that it was a code b2436 and b2909 they  recommended to replace seat belt and seat belt buckle which cost $382.00 for them both and 315.00 in labor without taxes. when I got it back from them I tried  unhooking the negative terminal to see if that would do it then it started this different blink as I described it above 5 and 2 before I unhooked the battery it had a different number of blinks and beeps it was all together different when I let the ford dealership read the codes I'm not sure of their diagnoses  since unhooking terminal now that the number of flashes and beeps have changed from before I unhooked the battery, any body have any suggestions please help
