Hi John. We do quite a few of these daewoo's and also use the jk100, we also got an unusuall fault code that we couldn't understand, so after trying a spare ecu and valve block, we tried the obvious (now) "yes it was the stop lamp switch". O.H and P.S. Ive never been able to find the abs pump motor either, and getting information is even harder. If the Info companies don't get their finger out and start giving some decent info, I think we ought to spend some time and make our own, at least that way it might be something like correct.
