The ABS light could be due to a bad brake light switch. A common point of failure, at least it's cheap and about a five minute job to replace. That was the case with my own '01.
I bought mine from Europarts SD - http://store.europarts-sd.com/switch...2001-2003.aspx
Note the comment "7th revision of this problematic part".
And Europarts SD is a good vendor, I've bought the transmission kit from them a few times.
