What is this?

Asked by May 19, 2017 at 06:49 PM about the 2012 Ford Focus SE

Question type: Maintenance & Repair

Can anyone tell me what that module is that's hooked up to the negative
battery cable? I just bought a used 2012 Ford Focus and that wire was left
unclipped, so I plugged it back in. I would like to know what it does.
