ABS Light on When Moving

[HyperGSX]

When I turn the key and start the car, the ABS light flickers normally then turns off. Once i start moving, the light comes on and stays on. This starting happening just after i did a high pressure carwash on my car. Any ideas?

Check your abs sensors. on the spindles in the front.
