# Service bulletin TEBE640800

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

There is a problem with certain truck models that were built with 2013 through 2015 model year CT13 heavy duty on board diagnostic \(HDOBD\) engines. These engines will require recalibration of the engine ECM and ACM \(aftertreatment control module\). Certain On Board Diagnostic \(OBD\) issues will be corrected which will aid in engine malfunction identification and proper diagnosis.
