Ok

First of all you will likely have no choice but to have the codes read. Usually the issue that causes the lights is either one of the wheel speed sensors or the steering angle sensor. The problem is you have several sensors on the vehicle and the fastest way to get to the one you need to diagnose is first by the code. Now, I think the issue is one of the speed sensors or the steering angle sensor because you don't have an issue until the vehicle is actually in motion. This does point to one of these sensors, but again, without a starting point, it's difficult to know which one to start with.
