I started the car this morning and the ABS warning light came on, i drove about a mile to a friends house, i was away from the car for literally 2 minutes. I fired it up again and the warning light had gone off. I've done a further 50 miles since, but no light.

Any ideas why it would do this? Its a my94 JDM WRX, so i thought it didn't have ABS?

The only option i came up with is that i jetwashed my arches yesterday evening so might have disturbed a sensor or something.
