Service bulletin TSB 602

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

Several coaches built after 2023 ECO 300 (before the issue was discovered) may not have the charge wire hooked up properly between the battery isolation module located in the PDC box in the front passenger side bay and the front Newmar fuse panel located under the driver’s side dash on the wall.

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.
