On the Lippert Ground Control 3.0 # LC358590 the error you are receiving indicates either a problem at the left front jack, a hall signal issue (open ground/short, or other malfunction) or an unexpected high amperage current stall (meaning the battery stopped providing power for some reason).

To clear the error you can either fix what is causing the error such as a loose or damaged wiring harness, or follow this method:

Extend all jacks at least 6 inches. Then press and hold the retract button until the jacks begin retracting. All of the jacks should fully retract and clear the error.

If you have a 6-point system the middle jacks only operate in error mode. To engage the middle jacks you would need to press the left and right buttons simultaneously.

Check the manual for the system because some things have to be done in a certain order for the system to operate correctly. That should prevent future errors (unless there is an actual electrical or mechanical problem).

The LR jack code means your left rear jack leg is not able to be controlled by the computer of the Ground Control 3.0 basically.

It is important that once the error code has been resolved, the user of the unit must manually
retract all jacks completely before exiting the error code. If this step is not completed, the LCD will
prompt the user to complete this step as follows:

Sample Error Codes
“ERROR”
“LR JACK”
“MANUALLY RETRACT”
“ALL JACKS”
“PRESS ENTER”
