That's not what I mean though. What I mean is, in the event that for whatever reason the signal to deactivate the electronic park brake cannot get where it needs to go using the scan tool, there has to be a way to do it manually.
Say your vehicle is in an accident. Say the electronic park brake wiring is in shreds. That brake caliper needs to come off. The body shop is going to require a way to remove it if the scan tool can't disengage it.
Say there's corrosion in the connector. Same same. Has to come off and be replaced. And so on.
Your vacuum doesn't go under furniture more than likely so to clean under there you quit being a janitor to become a furniture mover?
I guess it's turtles all the way down.
