It come on for no rhyme or reason. Doesn't matter if it's raining, dry, I'm driving or stopped. Obviously the parking brake is not on at all. Nothing I do makes it go away or prevents it from turning on.
My scantool shows no codes even when the brake light is on.
Is this a bad sensor? Maybe a problem with the computer?
Should I take it to the dealer, or would an independent shop be able to diagnose and fix this?

I own a shop, and have seen this exact problem. What it turned out to be was the switch on the emergency brake was out of adjustment. When you apply the emergency brake the switch is activated, and gives the light a ground to make it come on. If the emergency brake is not off good it will make it come on. If the switch is going bad it will do it too. You won't get any codes because there is nothing wrong with the system itself. When you let the emergency brake off, it pushes the switch to open the circuit, thus the light goes off. If the switch isn't pushed far enough, or right at the point where the switch clicks, it will do this.
Glad to help out, Good Luck!!!

It could be you're anti lock system, or it could be the park brake switch need tweaking. Its just a grounding switch way up on top of the park brake mechanism. Also the master cylinder has a reservoir fluid level sensor that uses that light. 1- check the master cylinder level. 2- the next time it comes on,make sure the park brake is all the way up. and 3- if none of this helps, the next time it comes on, mash the park brake slightly down and see if the light comes slightly brighter. If it dose, it's not the park switch. If it doesn't, and the master cylinder is full, then it's the anti-lock brake system. Oh, one other thing, you can buy these vans with front brake that ground when the pads get worn down. You might check to see if yours have this too.

check your brake fluid level. pad wear over time will decrease your fluid level because the fluid displaces into the caliper pistons to take up the spasce where the pad material used to be. also, old body style minivans were bad about the master cylinder filler neck leaking where it attaches to the master cylinder reservoir. there was a tsb. there is a revised filler neck with a revised seal. its only a few bucks. if for some reason it is the parking brake, disconnect the single wire that goes to the parking brake mechanism inside the van and see what the light does. then short it ro ground and see what the light does. if it doesn't change, its not a parking brake problem.

check the brake fluid level. I know nothing about your vehicle, but some cars warn of low fluid level by lighting the brake warning light. If the level is low, don't just top it up. Most likely it's time for new brakes (the fluid level drops as the linings wear) or worse, you have a leak.
The other likely culprit is an adjustment on the switch connected to the parking brake lever. Over time wear can throw it out of adjustment. If you look at the parking brake lever itself, you may see the switch and how it adjusts, usually by loosening a locknut and screwing the switch in or out on its bracket.

Sounds like the switch for the parking brake warning light needs to be adjusted. Let a pro do it.

There is a switch mounted on the brake mechanism under the dash. It is bad.
