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

Flash: Powertrain System Improvements/Enhancements This bulletin involves selectively erasing and reprogramming the Powertrain Control Module \(PCM\) with new software. The following powertrain system improvements/enhancements are included in this software release: ? Enhanced Automatic Oil Change Indicator\(EAOCI\) system enhancements that force the use of the severe duty cycle algorithm anytime the PCM is replaced. The vehicle duty cycle information used in the EAOCI calculation is stored in the PCM and cannot be recovered/transferred when the controller is replaced. As a result, the severe duty cycle is used in these scenarios to ensure the customer receives a timely oil change required message. ? Corrected a generic scan tool display issue regarding Mode 6 data accuracy. ? Improved Electronic Voltage Regulator control to more precisely maintain system voltage.
