Service bulletin CSB18-330-010B

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary

This service bulletin is an amendment to a previously submitted service bulletin, that applies to certain motorhome chassis, with additional parts segregated for the applicable models. The instructions in the document provide steps to install a proactive solution for the self leveling system supplied by Hadley to prevent it from operating continuously even with the vehicle ignition in the off position.
