Troubleshooting LCI Electronic Leveling

Updated 05/20/2021 | Published 05/17/2021

Question:

I had to manually retract legs and now the LCI module shows left arrow blinking and Jack’s down light. I have done reset with pressing down all four buttons front,rear,left and right. Still not working. I have unplugged control panel and still not working. System starts beeping if I release parking brake.

I don't know which exact system you have but the troubleshooting guide should be same for most systems, be it the # LC358590 or similar. It sounds to me that you may need to "Home" the jacks. Per the Ground Control 3.0 Troubleshooting Guide, page 8, Homing Jacks:

1. Introduce an error - disconnect one of the hall effect sensor wires at the controller.

2. Attempt to operate the jack that is associated with the sensor wire that was disconnected. The touch
pad screen will display an error for that jack.

3. Reconnect the hall effect sensor wire. Manually extend all jacks down a minimum of 6 inches.

4. Press and hold the retract button until all of the jacks begin to retract. The jacks will retract until they
reach the hard current limit.

5. The jacks are now “homed.”

NOTE: If the jacks do not retract, an error should display on the touch pad screen. This is typically caused by
wiring interruption.

NOTE: In order to "home" jacks, middle jacks must also be extended. Refer to Basic Jack Operation for
middle jack operation
