2001 land rover abs light comes on then goes out after you drive for a second is this normal?

No, this is not normal. The ABS (anti-lock braking system) light should only come on when there is a problem with the ABS system. If the light is coming on and then going out after a second, it could be a sign of a loose wire or a faulty sensor. You should have your vehicle inspected by a qualified mechanic as soon as possible.
