After doing Top of the World trail in Moab today the service 4wd light came on...what does mean? The offroad app also has error message..

Do you have a scan tool? It's hard to say what it is unless you get the error code. Could be nothing other than something related to the ABS, but hard to say unless you scan it.

Try shifting in and out of 4wd a few times? Something about when you put it in and out of 4wd while slowly moving, instead of at a dead stop. And then again, I could be totally wrong about it all. A few ideas.

I have a tazer mini won't that show any codes?

On all of my "pre start button" Dodge/Jeep cars, there has always been the trick of turning the key from "off" to "acc" three times in succession and all the codes would show up on the odometer (or on the radio for the really old ones that had mechanical odometers). Not sure is that trick still works... I have a '17 Viper with a start button and I never could get that one to work. Maybe there's some magic to it.

My suggestion to anyone who owns a modern car is to get a good Bluetooth scanner app for your mobile device. You plug the bluetooth transmitter into the OBDII port, you pair it with your mobile, and from there you can see everything that's going on with the car. I personally use the Torque OBD2 Engine Diagnostics app and it's saved me thousands in repair diagnostics.

The 4wd service light went off and the 4 wheel pages came up....go figure...?
