Service bulletin FS010

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

Certain T680 NextGen chassis equipped with an RCX230 Horton fan clutch and a Cummins X15 engine are experiencing an adapter harness failure. This failure causes the fan to remain activated while the truck is in operation and may trigger a check engine light and diagnostic trouble codes.
