# Service bulletin TSB130113\-111120

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.

- Published by NHTSA: 2020\-12\-14
- Manufacturer's number: TSB130113\-111120

## NHTSA's summary

This Technical Service Bulletin describes the verification and resolution of Fault Code 4585 becoming active after a calibration of the engine's Engine Control Module \(ECM\). This is caused by the engine not having a compatible aftertreatment Selective Catalytic Reduction \(SCR\) temperature sensor module. In this population of engines, a new SCR temperature sensor module must be installed to clear an active Fault Code 4585. This is an update to a previously submitted communication.
