That brings me to my next question. 2002 4.0L v6. I have the 4X4CM out and in my hands. Priced the new replacement on-line for $173.89 or the local junkyard for $50. Since the dashboard buttons stopped lighting up the dash, I assumed it is this module thats shot. At the same time, I lost traction control, and in the rain and snow, this truck slips and slides all over the place now. Does the 1L2Z-7E453-A control both 4 wheel drive and traction control? Reason I ask is the junk yard guy has a separate part and part number for a traction control module. Best as I can tell, I don't have that "AdvanceTrac" system as I have no separate on/off button for that, but remember if I was in 4X4 Auto, power would go to the left front or right front, if either of the rears slipped on ice or water. Don't think that's working anymore the way the truck is handling lately. That's why I need to know if the 4X4CM I took out is the culprit. P.S. ABS works fine.
