Flash: Powertrain Diagnostic and System Enhancements This bulletin involves reprogramming the Powertrain Control Module (PCM) with the latest available software. 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) stored in the PCM memory:P0456 - EVAP System Small Leak. U1424 - Implausible Engine Torque Signal Received. P0335 - Crankshaft Position Sensor Circuit. P0339 - Crankshaft Position Sensor Intermittent. P2299 - Brake Pedal Position/Accelerator Pedal Position Incompatible. P2227 - Barometric Pressure Circuit Performance. P1611 - Supercharger Bypass Valve Position Sensor 1 Circuit High. P0513 - Invalid Skim Key. P0300 - Multiple Cylinder Misfire (Sales Code DEC only). P1613 - Turbocharger/Supercharger Boost Pressure Sensor/Mass Air Flow Sensor Correlation. P1217 - Active Exhaust Valve 1 Performance. P121B - Active Exhaust Valve 2 Performance. The P0513 DTC is set during remote starting the vehicle and nearly simultaneously pressing the key fob button against the Keyless Ignition Node (KIN) causing an engine stall.The PCM software also enables freeze frame/failure records to be stored for the following diagnostic trouble codes:P0102 - MAF sensor circuit shorted to ground. P0103 - MAF Sensor Circuit shorted High. P0607 - ECU Internal Performance. P060E - Level 2 TPS Sensor Coherency Check Has Failed. P1610 - Supercharger Bypass Valve Position Sensor 1 Circuit Low. P1611 - Supercharger Bypass Valve Position Sensor 1 Circuit High. P1616 - Supercharger Bypass Valve Position Sensor 2 Circuit Low. P1617 - Supercharger Bypass Valve Position Sensor 2 Circuit High. P1620 - Supercharger Bypass Valve Control Open Circuit. P1627 - Supercharger Bypass Valve Position Sensor 1/2 Correlation. P162A - Supercharger Bypass Valve Actuator Control System - Max PWM Exceeded.
