Original wording in English
"Flash: Powertrain Control Module (PCM) Updates Customers may experience a Malfunction Indicator Lamp (MIL) illumination. Upon further investigation the technician may find one or more of the following Diagnostic Trouble Codes (DTCs) have been set:
• **P00F3-00 - Humidity Sensor Circuit Range-performance.**
• P00C6-00 - Fuel Rail Pressure Too Low - Engine Cranking.
• P06DD-00 - Engine Oil Pressure Control Circuit Performance/Stuck Off.
• P0461-00 - Fuel Level Sensor ""A"" Circuit Range/Performance.
• P051B-00 - Crankcase Pressure Sensor Circuit Range/Performance.
• P2F64-00 - Ion Sense Feedback Circuit A.
• P0331-00 - Knock Sensor 2 Circuit Range/Performance.
• P0300-00 - Multiple Cylinder Misfire.
• P2C90-00 - Crankcase Ventilation System - Hose ""A"" Disconnected.
• P0011-00 - Bank 1 Camshaft 1 Position Timing Over Advanced Or System Performance.
• P0604-00 - Internal Control Module Random Access Memory Ram Error.
• P060C-00 - Internal Control Module Main Processor Performance. **Customers may also comment on the following:
• Undesirable vehicle drivability behavior causing the a Shift to Park event during Engine Stop Start (ESS) while Adaptive Cruise Control (ACC) is active.
• Pressing ACC button while ESS active can shift the vehicle to park.
• Idle speed oscillations observed when in Snow and Mud modes.
• Poor engine performance (undershoots engine speed) for ESS and for non-ESS engine start.
• Screen two incorrectly pops up on the Instrument Cluster Panel (IPC) for 5 seconds during Terrain and Rock mode.
• Vehicle performance complaints when coasting at lower speeds.** This bulletin involves reprogramming the PCM with the latest available software."
