Which squib did it say (to save me looking up the code).  As that will be the clue ;)

Have you had the seats out, and not disconnected the battery first.

Has it got child seat detection on the passender seat? Has the yellow plug under the seat been connected properly?
An Elite I had years ago had a fault in the sensor in the seat which threw up the airbag light. There was only two ways to put the light out - one being to renew the sensor pad but it's stitched in so not a simple job, and the other isn't really the 'done' thing......
But as you have had the seat out then it's more likely to be the suggestions already given.

Put your code reader on a hard surface, and then use a tool known as a "Sammy" to adjust it properly.

77 is Driver Side Airbag squib high resistance.

Which is the airbag in the drivers seat.

Is the code marked as Present, Intermittent, or Not Present.  If your reader is too stupid, I suggest the adjustment above, but you'll also have to get a meter out. Squib should be approx. 4-5 ohms.  Obviously, use extreme care when measuring, and don't be near the airbag when you do.

If Not Present, it needs clearing.  Generic readers tend to struggle to clear non engine faults.
