94 chevy cavalier abs light and parking brake light

I have a 94 chevy cavalier and the abs light and the parking brake light are both on.I have replaced the caliper and the brake hose on the passenger side of the car.Could there be something else wrong with it?
If the ABS light is on, there is a problem with the anti lock brake system. Replacing the calipers and hoses will not fix it. A scan tool that will read the ABS data is needed to properly diagnose.
