Summary4WD Lamp Illuminated and Diagnostic Trouble Code C140F Active in Final Drive Control Modules (FDCM) Memory This bulletin involves verifying FDCM software level and then flash reprogramming of the FDCM with new software. Customers may indicate that the ?Service 4WD? indicator in the instrument cluster is illuminated. They may also indicate that the transfer case will not shift from 4WD High, 4WD Low, and/or Neutral once the lamp is illuminated. Further investigation identifies that a Diagnostic Trouble Code C140F is stored or active in the Final Drive Control Modules (FDCM) Memory

SummaryFlash: 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 ?
