After recently getting another 4WD Actuator replaced, a CEL came on and threw code P2609. My dealer replaced the Grid Heater. I went out this morning and started it up and the CEL turned off after start. So, good news since the Grid Heater did kick in due to the extreme cold temperature here in FL this morning, 61 degrees:-laf. Seems just cold enough to engage the heater. I have had such bad luck with this truck. Seems that parts that should not be faulting this early are breaking down.
