DTC problems

Very strange you are getting a code for Cylinder five and seven on a four cylinder vehicle. I looked up these codes and have found that it is a glow plug issue. They messed up some of the glow plug numbers to the cylinders they are supposed to go to in this design. Factory defect. If the Jeep is running fine, I would write the codes down, erase them and go for a good long test drive and see what comes back for codes. I was very hard to even find this little bit of information on this Jeep. There seems to be a lot of people with the same problem. Hope this helps a little. Let us know what you find.
