Service bulletin PM Sensor Shrtg

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

Supply chain shortage notice. Model Year 2022 Freightliner, Western Star, Freightliner Custom Chassis, and Thomas Built Bus vehicles manufactured with the following engines have been built without a Particulate Matter (PM)/Soot sensor: •DD15 Gen 5 (Gats 2.0) (with a June 2021 or later GHG build date) •DD13 Gen4 (1-box) (with a June 2021 or later GHG build date) •Cummins B6.7 (with a June 2021 or later GHG build date) •Cummins X15 with ratings of 400-500HP (with a June 2021 or later GHG build date) As a result, the vehicle has a non-conforming On-Board Diagnostic (OBD) system. The engine manufacturers will pay to install the OBD PM sensor and corresponding software through a recall once sensors become available.
