0602XX)** equipped with a 6.4L engine (Sales Codes ESA) or (Sales Code ESB) and with 6-Speed Automatic 66RFE transmission (Sales Codes DFP), or 6-Speed Auto Aisin AS66RC HD Trans (Sales Code DF3).
SYMPTOM/CONDITION:
NOTE: This bulletin fixes all vehicles listed and also contains an optional software path for 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 (optional software available for D2 & DJ vehicles).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 Malfunction Indicator Lamp (MIL) illumination. Upon further investigation the technician may find the following DTCs:
- **P0335 – Crankshaft Position Sensor Circuit.

- P3442 – Cylinder 6 Deactivation Control Performance.
- P3450 – Cylinder 7 Deactivation Control Performance.
- P2610 – PCM Internal Engine Off Timer Performance set in the PCM memory.
In addition to the DTCs listed above, the software update will improve:
- **Correct an issue related to rounding of the cruise control set speed displayed in the cluster.
- Brake Throttle Override calibration has changed to be less sensitive.
- Throttle Body supplier change has caused a widening of the minimum and maximum voltage limits
- Correct a software issue with oil pressure light function at key-up.
- Correct a software issue related to idle timer.
- Correct a software issue with inconsistent engine RPM increments/decrements with operator idle speed.(DD/DF/DP ONLY).**
- Improved Cruise Control Acceleration mode.
- Improved Multi Displacement System operation 6-Speed Automatic 66RFE transmission (Sales Code DFP).

- Potential small improvement in fuel economy at higher altitudes.
- Potential improvement in high altitude engine idle RPM stability.
- EGR monitor status function.
DIAGNOSIS:
Using a Scan Tool (wiTECH) with the appropriate Diagnostic Procedures available in TechCONNECT, verify all related systems are functioning as designed. If DTCs or symptom conditions, other than the ones listed above are present, record the issues on the repair order and repair as necessary before proceeding further with this bulletin.
If the customer describes the symptom/condition listed above or if the technician finds the DTC, perform the Repair Procedure.
REPAIR PROCEDURE:
NOTE: Install a battery charger to ensure battery voltage does not drop below 13.2 volts. Do not allow the charging voltage to climb above 13.5 volts during the flash process.
NOTE: If this flash process is interrupted/aborted, the flash should be restarted.
- Reprogram the PCM with the latest software. Detailed instructions for flashing control modules using the wiTECH Diagnostic Application are available by selecting the application’s “HELP” tab.
- Clear all DTCs that may have been set in any module due to reprogramming. The wiTECH application will automatically present all DTCs after the flash and allow them to be cleared.
