# Service bulletin 19517

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.

- Type: Service bulletin
- NHTSA id: 10168649
- Published by NHTSA: 2019\-12\-03
- Manufacturer's number: 19517

## NHTSA's summary

Under certain conditions functionality of the Exhaust Gas Temperature 5 \(EGT5\) and Selective Catalyst Reduction \(SCR\) Conversion Efficiency Monitors, may potentially result in an increase in NOx emissions. An Engine Control Module \(ECM\) calibration update to correct EGT5 and Conversion Efficiency Monitors will mitigate a potential increase of NOx emissions.
