I just ran by obd scanner and got a b2312 code. No lights on the dash. Should I be concerned?

If the power windows work normally, the B2312 code is likely from a switch held up or down for more than 20 seconds and is not a concern. Clear the code and monitor; inspect or replace the switch only if a window sticks or the code returns.
The owner of a 2011 Toyota Prius scanned code B2312 with no dash lights and no window problems. The expert explained that the code means a power window switch was held in one position for more than 20 seconds, either accidentally or because the switch is sticking. The owner said a child may have played with the buttons, and the expert agreed that is a likely cause if the windows operate normally.
