Hi all: I currently have a Sahara diesel with dual batteries. I am almost certain that the above problem regarding warning lights being displayed, particularly if it's multiple warning lights: (4 lo, VSC, traction, ect.) is due to low battery voltage. After replacing one battery, and then the other, I experience this problem until the new batteries received full charge, then all the lights went out. During the display of these warning lights, it doesn't allow the vehicle to be put into 4 Lo mode. This must be due to the battery power necessary to enable this transition. I would replace the batteries, then monitor whether they have received full charge with a voltmeter after a suitable time, and if not, would then look at the alternator. My bet though is batteries. All the best.
