A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned. - Type: Service bulletin - NHTSA id: 10121680 - Published by NHTSA: 2017\-11\-03 - Manufacturer's number: 18\-066\-16 REV. A - Manufacturer's date: 2016\-07\-16 - NHTSA component: FUEL SYSTEM, GASOLINE; POWER TRAIN; ELECTRICAL SYSTEM ## NHTSA's summary Flash: Powertrain Diagnostic And System Enhancements This bulletin involves reprogramming the Powertrain Control Module \(PCM\) with updated software. Some customers may describe one or more of the following: MIL Illumination Upon further investigation the technician may find that the following Diagnostic Trouble Codes \(DTCs\) have been set: · P2096 \- Downstream Fuel Trim System 1 Lean \(5.7L Engines\). · P2097 \- Downstream Fuel Trim System 1 Rich \(5.7L Engines\). · P2098 \- Downstream Fuel Trim System 2 Lean \(5.7L Engines\). · P2099 \- Downstream Fuel Trim System 2 Rich \(5.7L Engines\). Drivability Improvements: · MIL Lamp without DTC Active \- Permanent Fault Code Issue \(fix permanent fault code retention\). · ASD Relay \(to improve fuel pump relay initialization at key on\). · Fuel pump relay operation at key on. · Engine seems to lacks power at high engine RPMs \(5.7L and 4.7L Engines\). · Shudder or shake condition on wide open throttle stab during downshift event \(5.7L and 4.7L Engines\). · EVAP Diagnostic Enhancements. This diagnostic routine will be disabled while the vehicle is in decel fuel shut off mode.\(3.7L/4.7L Engines only\). · Audible knock sound on WOT launches \(DJ/DD 5.7L Engines only\). Transmission Improvements: · High engine RPMs needed before vehicle will upshift from 3rd to 4th. \(5.7L and 4.7L Engines\). · Harsh 1st to 2nd gear upshift \(5.7L and 4.7L Engines\). · Unexpected or busy downshift while coasting between 45\-48 mph \(72\-77 kmh\) \(DS 5.7L Engines only\). ## The document - [NHTSA's copy of the document (PDF)](https://static.nhtsa.gov/odi/tsbs/2016/MC-10121680-9999.pdf) - [If that address does not open, try this one](https://static.nhtsa.gov/odi/tsbs/2016/MC-10121680-0001.pdf) The document is the manufacturer's.
