# Service bulletin 18\-031\-15

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: 2.4L, 3.6L Powertrain System Improvements/Enhancements This bulletin involves reprogramming the Powertrain Control Module \(PCM\) with the latest available software. The following powertrain system improvements/enhancements are included in this software release: Vehicles equipped with a 2.4L engine \(sales code ED3 or ED7\). ? Charging system duty cycle enhancement to improve starting performance in low ambient temperatures. ? P219A \- Bank 1 Air\-Fuel Ratio Imbalance. \(applies to vehicles equipped with the 4 speed transmission \(sales code DFF\) only. ? 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. ? Mode 6 data accuracy enhancement for generic scan tools. Vehicles equipped with a 3.6L engine \(sales code ERB\). ? U0140 Lost Communication With Body Control Module. Attempting to clear the DTC may be unsuccessful. ? 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. ? Mode 6 data accuracy enhancement for generic scan tools.
