Service bulletin M1591
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
SERVICE BULLETIN M1591: INFOTAINMENT CONTROL UNIT (IFCU) SERVICE MENU. PURPOSE: This bulletin informs dealers of what to expect when using the Infotainment Control Unit (IFCU) Service Menu. Along with the instruction on how to convert Diagnostic Trouble Codes (DTCs) due to the temporary condition of them being presented in HEX format rather than SAE as is shown in the Electrical Diagnostic Manual (EDM). This will be corrected in a future software update for the IFCU.
