JeepDxb Posted August 29, 2011 Author Report Share Posted August 29, 2011 This is a transmission fault code. that will be needing a diagnostic test and for that a DRB3 scan tool, or equivalent aftermarket scanner will be required and the transmission simulator tool. When Monitored it was the pressure switch sense circuit and Set Condition set if one of the pressure switches are open or closed at the wrong time in a given gear.
