2015 JGC Eco Diesel - Service 4WD

2015 JGC Eco Diesel with 130K. Heard a fast clicking from the car and hard shift (random) and the service 4WD warning came up, but then went away. Ran fine and noise was gone. Used a code reader once home and no codes came up. What might be cause?

4wd service required JEEP CHEROKEE 2015

Hello. I have the same problem with the jeep. I was thinking of removing the PTU module, but today we found that it does NOT reach 12 volts, but 4 volts. Does anyone have any idea where the problem might come from?

Fuses

If the fuse is blown for either the PTU will the “service 4-wheel drive” light be on when you start the vehicle, or will the light come on after a few miles of driving?

Mine is not on when I start it. It comes on after I drive a few miles. It does go away until I turn the vehicle off and drive it again. Then it’s repeat.

Any ideas? 2016 Cherokee Sport Alt V-6 62,000miles.
