Yesterday I was cleaning with steam inside the coupe. Always pay particular attention not to get close to electronics with it, but somehow must have gotten some water near the parking brake button because now it will not work. I'm getting the "service electronic parking brake" DIC message. I checked the 30amp fuse up front and it looked alright (i know jcase fuses can look ok and be bad) I also tested it with an ohm meter. I also went thru and checked basically every fuse up front with the meter but not any of the trunk fuses. Tried disconnecting the battery for a period of time. Still nothing. Brakes will still engage and disengage by themselves (when turning off the car, and when leaving from a stop). Im hoping the water is just temporarily interfering with the system and it will work again. Im wondering if anyone knows how I could test the button itself with an ohm meter if I pry up the trim paneling right there to get to it. Or any other suggestions. Thanks in advance.
