Flash: MIL Illumination - Remote Start, Diagnostic and System Improvements This bulletin involves selectively erasing and reprogramming the Powertrain Control Module (PCM) with new software. Some customers may experience a condition that the Remote Start will not start the vehicle in cold 14° F (-10° C) ambient temperatures. Software enhancements will help this issue. Some customers may experience a condition that the Oil Life Monitor shows faster then expected oil life deterioration. Software enhancements will address this issue. Some customers may experience a Malfunction Indicator Lamp (MIL) illumination. Upon further investigation the Technician may find that any of the following Diagnostic Trouble Code(s) may have been set erroneously: ? P0087-00 - FUEL RAIL PRESSURE TOO LOW ? P0088-00 - FUEL RAIL PRESSURE TOO HIGH ? P016F-00 - CLOSED LOOP FUEL PRESSURE CONTROL AT LIMIT - PRESSURE TOO LOW ? P009A-00 - INTAKE AIR TEMPERATURE / AMBIENT AIR TEMPERATURE CORRELATION ?
