Service bulletin 08-079-14

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

18-095-152019-05-20. Service bulletin. Flash: 3.0L Powertrain Diagnostic And System Enhancements This bulletin involves reprogramming Powertrain Control Module (PCM) with latest available software. It also involves cleaning or replacement of Exhaust Gas Temperature (EGT) Sensor 1/2 and/or Catalyst Temperature Sensor if necessary depending on Diagnostic Trouble Codes (DTCs) that may have set. A small number of customers may experience a Malfunction Indicator Lamp (MIL) illumination. Upon further investigation a technician may find one or more of the following Diagnostic Trouble Codes (DTCs) set in 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. ? P1297-00 - EGR Slow Response - Decreasing Flow. ? P0420-00 - Catalyst Efficiency (Bank 1). ? P2237-00 - O2 Sensor 1/1 Pump Cell Current Circuit Open. ? P24D1-00 - Particulate Matter Sensor Regeneration Incomplete. ? U0422-00 - Implausible Data Received From Body Control Module. ? P1E0C-00 - Empty Fuel Tank. ? P2463-00 - Diesel Particulate Filter - Soot Accumulation. ? P24A4-00 - Particulate Filter Restriction - Soot Accumulation Too High. ? P2299-00 - Brake Pedal Position/Accelerator Pedal Position Incompatible. ? P208B-00 - Redundant Pump 1 Control Performance. ? P1288-00 - NOX Sensor 1/2 Zero Offset Too High. ? P2002-00 - Diesel Particulate Filter Efficiency Below Threshold. ? P204F - Reductant System Performance. ?
