OTC releases a software update at least once each year. Check OTC's website (www.OTCTools.com) for information. We try to list the latest software packs for every model, but it's a big chore. So, please call us for your particular model. We carry them all and will ship you the software update same-day. And, everything we sell is ALWAYS reduced at least 30% off. You won't find OTC diagnostic software updates cheaper.
