Troubleshooting Lippert Level Up Retract All Error After Replacing Hydraulic Jack
Published 08/31/2023
Question:
I purchased a new hydraulic jack from you. I have replaced the hydraulic jack, but the system controller is not responding. All of the jacks are in the up position, but it keeps erroring on retract all, even though they are retracted. Any info or manual on resetting the system would help.

It sounds like you need to perform a zero point calibration since you replaced your Jack # LC99ED. Here are the steps you will need to perform.
Level Zero Point Calibration
To set the zero point (controller module must be fully secured in production-intent location) activate the
Level Zero Point configuration mode.
This mode is enabled by performing the following sequence:
1. Turn panel off.
2. Press the FRONT switch 10 times (On Winnebago units, press FRONT 5 times).
3. Press the REAR switch 10 times (On Winnebago units, press REAR 5 times).
4. At this point, a beep will sound and the display reads ZERO POINT CALIBRATION. Do NOT press Enter.
5. Perform a manual leveling sequence on the coach.
6. Press ENTER to set the zero point.
7. Screen will then display Zero Point Stability Check and PLEASE WAIT.
8. Beep will sound and the screen will display ZERO POINT SUCCESSFUL.
9. Control will then turn off.
For Diesel Units with Air Bag Suspensions ONLY
The leveling control will automatically detect an air bag system. If the unit does not use air bags, the display
will read "NO" for air bag control. If the display reads "NO", but an air bag system is present on the unit:
1. Confirm harness is connected properly.
2. Run Auto-Level function.
3. Recalibrate the Zero Point.
4. If the air bag system is still not being detected, contact the OEM for more information.
