Question e-brake light stuck on?

This happened after I bought and OBD-2 light checker. I tried to delete my CEL's (which of course came back on in 5 minutes anyway).

In any case, weirdly, my e-brake light came on whether the handle is engaged or not, and won't go out.

Any ideas? What can I check for/tighten to fix this if it's just a coincidence with the OBD-2?

Thanks in advance.

The brake light has no connection to the ECU so it's just coincidental that it stayed on after you plugged your scanner in.
In addition to the switch for the e-brake, the light is connected to a level sensor in the brake fluid reservoir and will come on if the fluid level is low. So you should check your brake fluid as that is probably the reason the light is on now.
If you find the fluid to be low, don't just add more to fill it up. Check your brake pads first to see if they are worn and replace them if they are. As the pads wear the pistons extend farther out in the calipers and this causes the fluid level to drop. When the pads are replaced, the pistons are retracted back into the calipers and the fluid level will come back up. If you fill up the fluid reservior before changing the pads it will then overflow when you retract the pistons.
The other possibility is a leak somewhere in the system, which is not that likely on a newer car but not out of the question.

Thanks mulder, that makes sense. I will check levels when I haul the car out Friday. I have the stoptech kit and SS lines, but I installed them about 12 months ago, so maybe they are loosening? Something leaking? We shall see.

I see you are in NYC, do you do track days/AutoX? I need to get this car on some form of competitive process...

If you want to find out about local track and auto-x events, check out the Tri-State forum, there are threads and links for activities that will interest you. Many Tri-Staters are active with NASA, SCCA, and various other clubs that run auto-x's and track days.
