Limp mode basically prevents you from completing destroying your Jeep when something is wrong. Have you regeared the axle, put on lager tires, have any lights on the dash on?

I havent re geared my axle, but I do have large tires and the check engine light is on. I disconnected the battery for 15min and reconnect and nothing. I stepped on the gas and it wouldn't rev

Without starting the Jeep turn the key from the off position to the on position 3 times rather quickly leaving it in the on position on the third time. It should display a code.

It's better to use an external scanner to get codes. Many auto parts stores will scan free of charge.
The internal key method doesn't display all codes that may be set.

Yes an external scanner is better and many parts stores do it for free, but the internal scan was just a starting idea since it doesn't go over 15mph and and who knows how far they are from the parts store.
