The jeep has lights on for 4x4 service, ABS, ESP/BAS and traction control. Assuming they are all likely related to a similar issue, im looking for a starting point to diagnose the issues, where should i start?

Wheel speed sensors
Do you have a way to look at the signals?

No i dont, I have an OBD reader but it doesnt read ABS.
Is it likely that just a wheel speed sesnor will cause all those lights to come on together?
It did for me. It was the right rear sensor.
I have a Foxwell NT644 ELITE.
This let me look at the 4 sensors while driving and showed there was no signal from it.
But it's best to be sure, rather than just replacing all 4.
There are others, some have bi communication and Android or Apple based.
Just depends on your budget and desire.
But it saves a lot of trips to the dealership.
