I think it is indicating that there may be a weak short circuit somewhere. There is a simple test that you can do if you want. You will need a multi-meter that has an amp scale. I got one at Walmart for about $30. Then you remove the battery negative clamp, put the multi-meter between the battery and the clamp and see what the current is. There are on-line articles that will give you an idea what is normal. All cars have a little drain with everything off but if it is too high, the battery will not start the car at some point. You can find the individual circuit that is an issue by pulling fuses and retesting. My daughters old Corolla has a high drain in the circuit that powers the radio. I haven't taken the time to rerun the circuit, however so she just has to be careful not to let it set too long.
