## 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.
