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): ● **P06DD-00 - Engine Oil Pressure Control Circuit Performance/Stuck Off. ● P0073-00 - Ambient Air Temperature Sensor Circuit "A" High. ● P0071-00 - Ambient Air Temperature Sensor Performance. ● P2C90-00 - Crankcase Ventilation System - Hose "A" Disconnected. ● P1CEA-00 - Boost Side EVAP Purge System Performance. ● P05BD-00 - Stop-start Mode Switch Range/Performance. ● P00C6-00 - Fuel Rail Pressure Too Low - Engine Cranking. ● U0673-00 - Lost Communication With Ion Sense Module.** ● P00C6-00 - Fuel Rail Pressure Too Low - Engine Cranking - in ACTIVE or STORED status. ● P0325-00 - Knock/Combustion Vibration Sensor 1 Circuit - in ACTIVE or STORED status. ● P0330-00 - Knock/Combustion Vibration Sensor 2 Circuit - in ACTIVE or STORED status. ● P032A-00 - Knock-Combustion Vibration Sensor C Circuit - in ACTIVE or STORED status. ● P018B-00 - Fuel Pressure Sensor "B" Circuit Range/Performance - in ACTIVE or STORED status. ● P2AF6-00 - Starter Relay 3 Stuck Off - in ACTIVE or STORED status. ● P0300-00 - Multiple Cylinder Misfire - in ACTIVE or STORED status set during cold start catalyst heating. ● P0301-00 - Cylinder 1 Misfire - in ACTIVE or STORED status set during cold start catalyst heating. ● P0302-00 - Cylinder 2 Misfire - in ACTIVE or STORED status set during cold start catalyst heating. ● P0303-00 - Cylinder 3 Misfire - in ACTIVE or STORED status set during cold start catalyst heating. ● P0304-00 - Cylinder 4 Misfire - in ACTIVE or STORED status set during cold start catalyst heating. ● P0305-00 - Cylinder 5 Misfire - in ACTIVE or STORED status set during cold start catalyst heating. ● P0306-00 - Cylinder 6 Misfire - in ACTIVE or STORED status set during cold start catalyst heating. NOTE: To confirm the cold start catalyst heating, use WiTech Freeze Frame data, and confirm "Time Since Engine Start" less than 30 seconds and "Engine Coolant Temperature °F" less than 50 °C (122 °F) when Misfire Code was set. See Step 3 for more details. ● U0104-00 - Lost Communication With Cruise Control Module - in ACTIVE or STORED status. This software update will allow this permanent fault code to naturally clear. ● U0405-00 - Invalid Data Received From Cruise Control Module - in ACTIVE or STORED status. This software update will allow this permanent fault code to naturally clear. Customers may also experience one or more of the following: ● **Rough running engine. ● "Excessive Oil - Service Vehicle" message display in the Instrument Panel Cluster (IPC). ● Vehicle is difficult to start. ● Potential stalling when coming to a stop with an immediate restart. NOTE: If the engine were to stall while stopping, a message would display in the IPC informing the driver to shift to Park to restart the engine.* This bulletin involves inspecting and possibly reprogramming the PCM with the latest available software.
