Event code 551

Soon after turning on and driving I experienced a sudden break, I had not taken my feet off of either pedal. I turned it off, then back on again to get it out of the way to check the error code and it showed 551; I check error codes regularly and this one was different from the last. If these two things are related or unrelated, I would like to learn about both. Thank you.
