The diagnostic plug is under the hood near the battery and fuse box.
Jumper
TBS to GND (I used a small paper clip).

The long flashes are the first number and the short flashes are the
second.
For example one long and 3 shorts = 13.

Mine fixed themselves after I did a rear brake job, look for other
problems first. Also try cleaning the sensors, they have a magnet
int then and all kinds of metallic crap tends to stick to them.. The
rear sensors are behind the brake rotors. The sensors are expensive
so you won't want to change them if you don't have to.
Hope this helps,
