Other FDM-IB-005

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 bulletin provides instructions for installing an updated park brake valve pressure switch to eliminate the "sticking" switch issues, as well as the unintended horn alarm when the cab door is open. The updated pressure switch has a higher pressure activation and reset values which reduces the delay experienced with the previous pressure switch.
