to be honest mate it probably hasnt as it is a mk1. i think only the hlx/hgt came with abs: both series. the easiest way to find out is simply to turn the ignition on and a light will appear that says abs in a sort of circle.
if you are positive you do have it but no light appears then try your fusebox as the fuse may have one.
i wont say what the other alternative is.....
you have to trythat one yourself lol.
i may be wrong though as some people had abs fitted at the original time of purchase as an optional extra.
