Service bulletin 1ZPK8A2M11

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 Technical Service Bulletin provides an inspection guide and corrective actions for travel trailers produced during 2014 and 2015 that may experience degraded braking due to a sub-optimal ground through the ball connection when an optional anti sway hitch is installed. During the affected model years some Oliver models relied upon providing a ground to the electric braking system through the connection between the tow vehicle hitch and trailer frame. This usually provides sufficient grounding capacity for the brakes to operate normally, however, a better method of grounding the trailer would be to provide a grounding bond through the 7-pin ground wire to the trailer frame.
