As far as seriousness, remember that it's just a reading, and it won't affect the actual operation of the vehicle itself.
A TSB is simply a set repair for something that occurs under a certain condition, it's different from a campaign or recall. Acura won't pay for the performance of a bulletin when the vehicle is out of warranty, unless, of course, you have an extended warranty contract.
A one hour diagnosis charge seems high, but it may be mandated if the problem exists due to a wiring or logic issue, rather than component failure.
