Chrysler Computer Glitch
A “small number” of 2014 Chrysler 300, Charger and Challenger models equipped with a 3.6L engine and built on or before 9-27-2013 may experience a MIL on, with DTC P0606 (internal control processor) set.
A software release to correct this also includes an accuracy improvement for the automatic oil change indicator system that allows the PCM to retain current usage/duty cycle information when the controller is reprogrammed.
Using a scan tool, verify that all engine systems are functioning as designed and record and correct any other DTCs.
Reprogram with release 14.01 or higher.
