Erase the code, then see if it comes back. I doubt it will. Most computers have memory circuits that draw a very small amount of current to keep them alive. As far back as the late 1980s, Chrysler allowed up to 35 milliamps, (0.035 amp), for that "ignition off draw, (IOD) current. Today that is the industry standard unless the manufacturer specifies otherwise. Cadillac, for one, allows up to 50 milliamps. At 35 milliamps, a good, fully charged battery will be strong enough to crank an engine fast enough to start after sitting for three weeks. It's common for them to go longer, say four to five weeks, but any longer than that, it's wise to connect a battery maintainer. Those even come in solar-powered if the vehicle will be sitting in sunlight. That IOD current is what runs batteries down now when the vehicle sits, and is what some computers will see as "low voltage". They set that code because if system voltage remains too low while driving, it can affect proper operation of some high-current circuits. That includes solenoids in anti-lock brake hydraulic controllers, automatic transmissions, and fuel injectors.
For emissions testing, it's the Engie Computer and its fault codes you're interested in. Those can detect over 2,000 different defects, each with its own very specific code number. Only about half of them refer to things that could adversely affect emissions. Those are the codes that turn on the Check Engine light. Since that light is not commanded on, there should be no problem passing emissions tests. If you're referring to a safety inspection, erase that code in the ABS Computer, but if it kicks in when a brake begins to lock up, the system is working and the code can be ignored. There's usually a strategy for codes to self-erase after a certain number of engine starts if the problem doesn't occur again
For emissions testing, the other thing they usually look at is the "monitors". Your scanner shows two as "incomplete". Some of them have very long lists of conditions that must be met for them to run. Best is to get the list from the dealer if getting them to run is necessary. The list can include things like, must see wide-open-throttle briefly, must see a steady highway speed for a specific amount of time, must see certain other specific conditions or driving maneuvers, etc. Every model's list is different, but it is supposed to include things we normally do anyway.
