Since ABS light is active before ever driving, the self test has failed. Self test failures are an open or shorted sensor or its wiring, poor supply voltage or ground, or internal EBCM failure.

You can guess all day long, but, having the fault code will save you a tremendous amount of time in narrowing down what to inspect/ test/ replace.
