Flash: 3.0 L MIL Illumination Diagnostic and System Improvements
This bulletin involves reprogramming the Powertrain Control Module (PCM) with the latest
available software.
A small number of customers may experience a Malfunction Indicator Lamp (MIL)
illumination. Upon further investigation the Technician may find one or more of the
following Diagnostic Trouble Code(s) may have been set:
