Service bulletin PIB 541

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

Some coaches equipped with both the SilverLeaf system and a TRC transfer switch (model 40350RVC-40350RVC3) may receive a warning on the SilverLeaf touchscreen that reads “transfer switch 0-0 failure unknown.” This is a false warning caused by the TRC transfer switch program code.

The document

The document is the manufacturer's. This site does not hold it. NHTSA files a document at one of these two addresses; we have not asked NHTSA which.
