yes it means the battery voltage is low
when the line contactor is closed the system is seeing voltage below 22v.
the logic card needs to see correct battery voltage at connector pin locations CN2-34, 39, 40, 41, 42.
have your battery tested and make sure all the cells are ok, a couple of bad cells can cause a severe drop triggering this code.

Usually means the system detected battery voltage below 22v.
