Service bulletin SB54-342

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

Freightliner Service Bulletin for Rain/Light Sensor Removal. On New Cascadia vehicles, a delay in the timing of communication (hand shake) between the rain/light sensor (RLS) and sSAM generates fault code "33/521940/12 - rain/light sensor - general DTC timeout", which causes the sensor to stop working.

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.

Electrical system, Equipment and accessories

Listing a model year does not mean every vehicle of it is concerned: the document says which.

A recall listed here may apply to some of the same vehicles. Only the manufacturer can say whether it applies to one vehicle.
