To hatcity, no roosters is long gone. Was a great place to eat. Think its a mexican place now. Not sure if my tech tools will reprogram, maybe a dealer thing, my understanding from the dealer rep I work with is that has to be done through volvo since its a volvo engine, even at the dealer, but not positive. This truck uses no def fluid. It works without it. Still learning about the regen systems. Being a small independent shop, have to learn the hard way. Have all dealer software for most engine makes and took a while to find it. Mack was the only one to actually sell me the software out right. If problem persist I will check on the reprogram. Challenger, you sound as if you might work at a dealer or well versed shop. Just curious. Either way thanks for the info.
