So my car will randomly do this. It says stop, and then brake fault, and then service manual. Then the screen just goes back to normal, telling me my miles until empty. My car brakes just fine and nothing seems out of the norm.
When mine did that, it was the ABS module. It didn't do it often though. It's unplugged now and I haven't had any problems. Except for not having ABS, and having the lights flash and beep when I start the car.
