Service bulletin 08-046-16

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.

18-096-162022-08-15. Service bulletin. Flash: 6.4L Diagnostic And System Improvements This bulletin involves selectively erasing and reprogramming the Powertrain Control Module (PCM) with new software. NOTE: **This bulletin contains optional software update that should only be used in situations where the customer is specifically complaining of a Drone Noise, Shudder, Pulsation, or Vibration under light throttle applications while vehicle is operating in MDS/ECO mode. There will be two separate software options displayed on the wiTECH flash tab. The software file released for this condition contains the verbiage ?OPTIONAL?.
