Re: No 4WD Low

Jeep/FCA had a recall a couple years back to preform a reprogram of the FDCM (final drive control module) that caused a "service 4wd" message to appear. FCA released a second reprogram to "fix" their first "fix". Chances are the dealer did that second reprogram. Hopefully you will not have anymore problems. Google the following keywords: Jeep N23 Recall
