# 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.
