Today I had a weird one. Was in my driveway and it had just snowed. 10cm. I went to back up in the driveway slowly so the AWD could do its thing. Well... I put myself into 2 holes because the front tires were doing shit all. Got the service 4wd on the dash. Went and got the codes read by a buddy, and these are what came up.
C140DC - Transfer Case Motor Control Circuit Open
C140AC - Transfer Case Motor Performance
Is the motor bad? Or is it the electronics surrounding it?
if you have had the recall N23 done on your jeep , this is the problem .
You need to go to your dealer they need to clear the codes for the 4wd
There are plenty of guys having the same issue , I was unfortunately one of the firsts
If you have a OBDII code reader you can try to clar the codes yourself
