ABS Light

[Wildstar]

When I start my car all of the lights on the dash go out.
But when the car starts moving, the ABS light comes on
almost immediatly.

What I'm thinking is that one of the wheel sensors must be bad,
the ABS computer knows the car is moving, due to getting data
from the other wheels, but is missing data from one of the
wheel sensors.

Is there any way to get the ABS computer to give codes like
the engine computer will?

Thanks
