How to disable 2015 renegade safety feature ?


New member
Ok so when the check engine light comes on the jeep automatically disables access to all 4WD modes on my 2015 Jew renegade Trailhawk. How do I disable this annoying feature in case there is a zombi apocalypse one day or something. I don’t want to be stuck stranded. Is it an ECU reprogram or how do I go about removing this feature?
