    First... don't go to TA or Petro for that stuff. When you changed the purge valve, did you change the canister, as well?
    Although, to be honest, it could just as easily be an electrical gremlin. If you're going to go to a shop, go to one which has the appropriate software, such as Insite (if a Cummins) or Davie (if a PACCAR), as well as ESA - the latter will be particularly helpful if your purge valve issues are electrical in nature (as I suspect they might be).... as for the rest of it, does your truck have or has it ever had a PTO? I wouldn't be worried about the message itself so much as I would be the possibility of it coming down to a multiplexing error (which aren't unheard of on those trucks).
    As for ABS, start by checking the fuses. Other than that, the most common cause of those lights which I've encountered have been wheel speed sensors. ProLink or the Bendix software can pinpoint which one if that's the case.
