Flash: MIL Illumination - Diagnostic and System Improvements
This bulletin involves selectively erasing and reprogramming the Powertrain Control
Module (PCM) with new software.
Some customers may experience a Malfunction Indicator Lamp (MIL) illumination. Upon
further investigation the Technician may find that any of the following Diagnostic Trouble
