Flash: MIL Illumination Diagnostic and System Improvements
This bulletin involves selectively erasing and reprogramming the Powertrain Control
Module (PCM) with new 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 erroneously:
? P0087-00 - Fuel Rail Pressure Too Low.
? P20EE-00 - SCR NOX Catalyst Efficiency Below Threshold Bank 1.
? P0171-00 - System Too Lean (Bank 1).
? P0172-00 - System Too Rich (Bank 1).
? P225C-00 - NOX Sensor Performance - Signal Stuck High Bank 1 Sensor 1.
? P225D-00 - NOX Sensor 1/1 Performance - Signal Stuck Low.
? P1288-00 - NOX Sensor 1/2 Zero Offset Too High.
? P1289-00 - NOX Sensor 1/2 Zero Offset Too High.
? P1296-00 - EGR Slow Response - Increasing Flow.
? P1297-00 - EGR Slow Response - Decreasing Flow.
? P2BA9-00 - NOX Exceedence - Insufficient Reagent Quality.
? P2080-00 - Exhaust Gas Temperature Sensor Circuit Performance.
