Flash: 3.0L Powertrain Diagnostic And System Enhancements
This bulletin involves reprogramming the Powertrain Control Module (PCM) with the latest
available software.
A small number of customers may experience bucking under hard acceleration. In
addition other customers may experience a Malfunction Indicator Lamp (MIL) illumination.
Upon further investigation a technician may find one of more of the following Diagnostic
Trouble Codes (DTCs) set in the PCM memory:
? P1296-00 - EGR Slow Response - Increasing Flow.
? P249C-00 - Excessive Time To Enter Closed Loop Reductant Injection Timing
Control.
? P20C2-00 - Reductant Heater 3 Control Circuit Performance.
? P24A4-00 - Particulate Filter Restriction - Soot Accumulation Too High.
? P24D1-00 - Particulate Matter Sensor Regeneration Incomplete.
? P1288-00 - NOX Sensor 1/2 Zero Offset Too High.
? P1289-00 - NOx Sensor 1/2 Zero Offset Too Low.
