Hello, The other day, I was driving my 2005 Prius uphill and when I pressed on the brakes at an intersection (that was at the top of the hill), these 3 warning signs showed up. I pulled over for 10 feet, parked it and got a ride from someone else. Called Toyota and didn't give me much info, other than to have it towed to a dealership for a diagnostic. My dad tested it with a computer and got no error codes, but went to a mechanic who got these error codes. Any idea of what it could be? I didn't have a problem driving it back home so I don't know what it could be.
