Software Update for Acura TL

I have a 2012 Acura TL. I’m getting a “Replace Battery” warning, however the battery, alternator, and starter all passed a failure check.

I’m learning this warning maybe connected to a software glitch and that the vehicle may need a software update. Amazingly, Acura’s support cannot tell me whether or not my vehicle has the latest software (it’s version 2.12).

Does anyone know what version of software is the most recent for a 2012 Acura TL? The software version is found going to System/Device Information.
