# 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.

- Type: Service bulletin
- NHTSA id: 10155399
- Published by NHTSA: 2019\-03\-27

## 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.
