Service bulletin 0901323

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.

9100692 Rev 12026-05-28. Service bulletin. On Cummins diesel applications that are for 2019 and newer the bpro part 1BP00507AB can on occasions create a check engine light. In these situations, it is recommended to use the appropriate Mopar air filter originally installed on the vehicle. The "AC" level of the part is in development to resolve this issue. 1BP00507AB should still be usable for 2018 and older Model year Cummins engines.
