Preventive Maintenance
Special Jack Error Codes
1. Remove dirt and road debris from jacks and stabilizer struts (if equipped) as needed.
2. If jacks are down for extended periods, it is recommended to spray exposed leveling jack tubes with
a spray lubricant every 3 months for protection. If the coach is located in a salty environment, it is
recommended to spray the rods every month.
Ensure the coach is supported at both the front and rear with jack stands before performing any
troubleshooting or service to the unit. Failure to do so may result in death or personal injury.
To clear one of these errors:
1. Correct or otherwise repair the issue (see the table below).
2. Extend all of the jacks at least six (6) inches, then press and hold the “RETRACT” button on the touch
pad until the jacks begin retracting.
3. All of the jacks will retract fully to clear the error.
