Service bulletin 11-190-19

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

This bulletin announces availability of ECM reprogramming files to optimize the ECM. The new files contain logic which will revise: ? the ECM detection of DTC U0122 ? the EGR flow rate to address a limited number of customer concerns about a slight hesitation felt while driving at highway speeds and using the cruise control.
