rogersenergi Posted May 19, 2015 Report Share Posted May 19, 2015 The Recreational Towing instructions attached to this TSB differ in two ways from the owners manual:1. In the owners manual there is a bullet referring to ACC mode; this is not in the TSB.2. In the owners manual the last bullet ends "...engine in the accessory mode." In the TSB this is modified to "...engine in the off position." So, leave it in the off position and don't go to ACC mode. That alone has kept my battery from discharging. The reprogramming of the Powertrain Control Module to the most up to date version is therefore just a "nice to have" and is covered under warranty.
