Service campaign CB784

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

The Thermo King TXV valve supplier made modifications to the superheat setting on the Bus TXV valve (PN 615185) prior to receiving approval from Thermo King. Upon being notified of the quality concern, Thermo King conducted an assessment and identified that a total of 321 Bus units in the field are at risk. This issue requires prompt action to manually re-adjust the valves on the affected units to ensure they operate within an acceptable range.

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.

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