Had my independent Jag repair place change oil and reset airbag light (got into fender bended and had to repaint bumper)

Had:

Code 17
P-2291
28 Operating Calibrating Fault

What do these codes mean?

Also, he said the right rear short bushing on the shock absorber had some play. Can this bushing be replaced, or does the whole shock have to be swapped?

 

Found out the bushing can be replaced on its own. $30 part.

Still no update on what those codes mean... :-(

 

Its b2291 flash code 17 spacial or sonic sensor for passenger, i wouldnt worry about it unless it returns. Someone may have had a sonic sensor unplugged and cycled the key on. And there's not a flash code 28, but since they were typographically challenged on the b code, maybe the 28 too
