Service bulletin SU2103

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 intent of Service Update SU2103 is to announce a new Shaw Development Technical Bulletin. The Technical Bulletin is intended to guide Shaw Development customers in troubleshooting fault codes related to the DEF tank assembly on Cummins engine equipment. This document is intended to be a “living document”, and the details and processes within can/will change as system designs evolve, or other new information comes to light. Access to this Shaw Development Technical Bulletin will be available on the Blue Bird Vantage website.
