Flash: 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. These enhancements are listed by vehicle application.
DS vehicles equipped with a 3.6L engine (sales code ERB).
* Enhanced Automatic Oil Change Indicator (EAOCI) system improvements to switch to a severe duty cycle algorithm anytime the PCM is replaced to ensure the customer receives a timely oil change required message.
* Corrected a generic scan tool display issue regarding Mode 6 data accuracy. DS vehicles equipped with a 5.7L engine (sales code EZH).
* System improvements to prevent Malfunction Indicator Lamp (MIL) illumination with a Diagnostic Trouble Code (DTC) P0300 - Multiple Cylinder Misfire when using a block heater in ambient temperatures greater than -20°F (-29°C).
* Enhanced Automatic Oil Change Indicator (EAOCI) system improvements to switch to a severe duty cycle algorithm anytime the PCM is replaced to ensure the customer receives a timely oil change required message.
* Corrected a generic scan tool display issue regarding Mode 6 data accuracy. DJ, DD, and D2 vehicles equipped with a 5.7L engine (sales code EZC or EZF).
* U0140 - Lost Communication With Body Control Module (attempting to clear this DTC will be unsuccessful).
* Transmission torque management enhancement when shifting from drive to reverse.
* Software to correct Malfunction Indicator Lamp (MIL) illumination with Diagnostic Trouble Code (DTC) P0481 - Cooling Fan 2 Control Circuit/Open setting in the PCM memory.
* Enhanced Automatic Oil Change Indicator (EAOCI) system improvements to switch to a severe duty cycle algorithm anytime the PCM is replaced to ensure the customer receives a timely oil change required message.
* Corrected a generic scan tool display issue regarding Mode 6 data accuracy.
* Improved tran
