Service bulletin 18-016-15

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.

NHTSA's summary

Flash: 6.2L 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 a Malfunction Indicator Lamp (MIL) Illumination. Upon further investigation, the technician may find one or more of the following Diagnostic Trouble Codes (DTCs) stored in the PCM memory. ? P0300 - Multiple Cylinder Misfire (manual transmission applications only). ? P1613 - Turbocharger/Supercharger Boost Pressure Sensor/Mass Air Flow Sensor Correlation. ? P2227 - Barometric Pressure Circuit Performance In addition, customers may also comment that, with the cluster set on metric units, they are unable to accurately increase or decrease the cruise control set speed using the resume or set buttons. Instead of changing vehicle speed by 1 KPH when pressing the buttons, the vehicle speed will increase approximately 1.6 KPH.
