SUBJECT: GROUP ENG MODEL All Models w/2.4L GDI NUMBER PS327 DATE June 2014 RESETTING CYLINDER BALANCE ADAPTATION VALUES When addressing a cylinder balance concern on a vehicle equipped with a 2.4L GDI engine, it is important to note that the DTC may recur after replacement of any faulty component(s) and resetting adaptive values. Adaptive reset function did not previously contain the ability to reset cylinder balance values, allowing the possibility for these values to remain out of the allowable threshold, and triggering the DTC. To ensure proper repair of a vehicle with this concern, GDS software version must be at least N-K-01-13-0022 or later. GDS software updates after this point contain the ability to reset cylinder balance adaptation values. NOTE: PCM replacement for this concern without first updating GDS to the latest version may be subject to warranty chargeback. Page 1 of 1
