Well, we would look to see if it's got electronics on it. If it doesn't, then we don't have to worry about scanning codes at all. And then the next thing is check condition of the fluid, the fluid pressure, make sure that's accurate. We get it up in the air and sweep the wheels back and forth by hand to make sure that they turn properly.
