Flash: Powertrain Control Module (PCM) Updates Customers must experience a Malfunction Indicator Lamp (MIL) illumination and the vehicle must exhibit/set one or more of the following Diagnostic Trouble Codes (DTCs):
• P00C6-00 - Fuel Rail Pressure Too Low - Engine Cranking.
• P0325-00 - Knock/Combustion Vibration Sensor 1 Circuit.
• P0330-00 - Knock/Combustion Vibration Sensor 2 Circuit.
• P032A-00 - Knock-Combustion Vibration Sensor C Circuit.
• P018B-00 - Fuel Pressure Sensor "B" Circuit Range/performance.
• P2AF6-00 - Starter Relay 3 Stuck Off.
• P1CEA-00 - Boost Side EVAP Purge System Performance.
• U0104-00 - Lost Communication With Cruise Control Module and U0405 - Invalid Data Received From Cruise Control Module may also be set. This software flash will allow these permanent fault codes to naturally clear. Customers may experience the following:
• A potential to stall when coming to a stop with an immediate restart. If the engine were to stall while stopping, a message would display in the Instrument Panel Cluster (IPC) informing the driver to shift to park to restart the engine. Other software improvements:
• **High pressure fuel pump actuation during cold start have been changed to shorten the cranking phase.**
• Improvements related to fault codes P0300, P0301, P0302, P0303, P0304, P0305 and P0306 for cold start catalyst heating misfire. **This bulletin involves inspecting and possibly reprogramming the PCM with the latest available software.**
