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 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
