Nissan Repair Questions? Ask a Mechanic for Answers ASAP
hey there, thanks for the question.
What your referring to is an intertia switch. Nissan has never used one so that's definitely not the issue.
If you lost all power after hitting a large pothole, I would bet you have a lose battery cable or something of that nature and it jarred lose when you hit the pot hole.
So start with the battery connections, you shouldn't be able to wiggle the battery terminals at all.
