Hi there. These lights can come on for any number of reasons. If they came on right after the battery was replaced then you may have caused a fuse to blow or may have caused a short. Any time there is a loss of voltage in this system then these lights can come on. I would typically disconnect the battery and then reinstall the connections. If that does not help then I scan the computer and then possibly reprogram it. If the problem still persists then it may be caused by a steering angle sensor, a speed sensor, or any number of other sensors.
