The LR Jack error code is identifying that there is an electrical issue with the left rear jack of your Lippert Ground Control 3.0 Electric 5th Wheel RV Leveling System # LC358590. You will need to check the fuse on the main controller for damage as well as the connections and wiring for the jack. Once you have all the wiring checked and if the jack starts to work again you will need to rehome all the jacks. This is done by extending all the jacks at least 6" and using the retract all button for the computer to rehome all the jacks.

If you cannot find any wiring issues you may have a bad jack, you need to manually retract the jack to get it to a service center or home. You can retract your jack with a 3/8" ratchet and extension on the top access point. If you cannot access the top port there is a access port on the bottom but you will also need a 5/16" socket.
