What does esp bas mean on a 2009 Jeep Compass?

Let's cover the definition, first. ESP expands to Electronic Stability ProgRam, and the BAS means Brake Assist ProgRam. Both of these systems contribute to the safety of Your 2009 Jeep Compass, though You don't often interact with them, as they only engage in emergency situations. So, some things You may encounter here is the ESP BAS light illuminating, not having any anti-lock brakes, or seeing the traction control deactivated. The most common reason for the ESP BAS light is the steering angel sensor. To reset the error if this is the cause, You can turn the steering wheel twice to the right, then twice to the left, (and You put Your elbow in, and You take Your elbow out...) and finally back to the center.
