My 2014 1500 with the 3.6l has been throwing the OBD code P26ab on and off for the past few weeks. After looking around online it seems that either a simple pcm update could fix the faulty code or the coolant bypass valve is bad and needs replaced. Im over 36k therefore it would not be covered under warranty. I'm taking it to the dealer for a recall issue and just want to make sure they actually flash the latest pcm update before just defaulting to a bad coolant bypass valve. Any way i can check the version before and after?
