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?
How to disable 2015 renegade safety feature (4WD dsable whn chk eng lot on)?

The easiest thing to do is repair the CEL.
To find the CEL code you could do the key dance or get a code reader.
The key dance: without starting the vehicle turn the from off to the on position three times within 5 seconds. Off/on off/on off/on
And the code will pop up in the odometer.
Post up what codes come up.
