# Service bulletin 18\-096\-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. - Type: Service bulletin - NHTSA id: 10135118 - Published by NHTSA: 2018\-05\-07 - Manufacturer's number: 18\-096\-16 - Manufacturer's date: 2016\-08\-19 - NHTSA component: POWER TRAIN; ENGINE AND ENGINE COOLING ## NHTSA's summary 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?. The other file is the standard software that does not contain improvements for the Drone/Shudder concern. If for some reason the customer finds this shudder improvement objectionable, the PCM software may be returned/reflashed to the standard version. Both software versions will address the remaining conditions noted in the bulletin. A small number of customers may experience a surge, shudder or pulsation type sensation when driving on smooth road surfaces at highway speeds of 64\-129 km/h \(40\-80 mph\).\*\* During normal diagnostics a technician may find one or more of the following Diagnostic Trouble Codes \(DTCs\) present: · \*\*P0335 \- Crankshaft Position Sensor Circuit.\*\* · P0300 \- Multiple Cylinder Misfire, cold Idle misfire \(DJ,D2 or DD vehicles only\). · P030X \- Cylinder Misfire \(any cylinder\). · P04D1 \- Cooled EGR Temperature Sensor Circuit High. · P04D0 \- Cooled EGR Temperature Sensor Circuit Low. · P2504 \- Charging System Output High. · P0441 \- Evap Purge System Performance. · P2066 \- Fuel Level Sensor 2 Performance. · P0401 \- EGR System Performance \(DJ/D2 vehicles only\). · P2096 \- Downstream Fuel Trim System 1 Lean \(DD/DP vehicles only\). · P2098 \- Downstream Fuel Trim System 2 Lean \(DD/DP vehicles only\). · ## The document - [NHTSA's copy of the document (PDF)](https://static.nhtsa.gov/odi/tsbs/2016/MC-10135118-9999.pdf) - [If that address does not open, try this one](https://static.nhtsa.gov/odi/tsbs/2016/MC-10135118-0001.pdf) The document is the manufacturer's.

AIR CLEANER \- NONE Instruction to Dealers while ordering the PN\# 68137142AD. 1. If the Air Cleaner Assembly is functional and only the MAF Sensor has failed, the dealer should order and replace only the MAF Sensor\(68002441AC\). 2. If the Air Cleaner Assembly has failed and the MAF Sensor remains functional, the dealer should order the new Air Cleaner Assembly PN\(68137142AD\) and reuse the existing MAF Sensor\(68002441AC\) from the failed assembly. 3. If both the Air Cleaner Assembly and the MAF Sensor have failed, the dealer should order both the New Air Cleaner Assembly\(68137142AD\) and the MAF Sensor\(68002441AC\) as separate service parts. - [112906](/bulletins/11034373.md), 2026-07-02, Service bulletin: ENGINE.
