NOTE: This Service Bulletin applies to HB/HG/DJ/DS/DH/DC/ND vehicles equipped with a 3.7L, 4.7L or 5.7L engine (Sales Code EKG, EVE, EZC, EZD or EZH) and a 4 speed 42RLE or 5 speed 545RFE or 6 speed 68RFE automatic transmission (Sales Code DGV, DGQ or DG7).
The customer may experience a Malfunction Indicator Lamp (MIL) illumination. Upon further investigation the Technician may find that any of the following Diagnostic Trouble Codes (DTC’s) have been set.
- P050D – Cold Start Rough Idle
- P2181 – Cooling System Performance has been set
- P0935 – Line Pressure Sensor Circuit High All RFE transmissions
- P0300 through P0308 – Multiple and Single Cylinder Misfire. This condition can occur when the vehicle is started cold and the driver immediately places vehicle in drive and applies heavy throttle.
Driveability and Transmission improvements are also included with this software release. These changes consist of the following:
- Enhanced clutch protection for more robust torque management during repeated fore and aft movement (rocking vehicle) all engines.
- A revised torque convertor lockup schedule that will reduce transmission temperatures in Tow/Cruise mode All models equipped with RFE transmission.
- A Clunk sound or feel a shudder when the cruise control resume switch is pressed. This condition is most noticeable after the brakes were pressed to cancel cruise control and then the resume switch is pressed All models equipped with RFE transmission.
- A shudder or shaking feeling when a wide open throttle (WOT) event is performed by the customer. This is most noticeable after the transmission downshifts during the WOT event. This condition will stop once the transmission upshifts All models equipped with RFE transmission.
- A shudder or shaking feeling when accelerating from a stop under moderate throttle. This condition will stop once the transmission upshifts All models equipped with RFE transmission.
- A shudder or shaking feeling after the transmission downshifts. This condition will stop once the RPM’s drops All models equipped with RFE transmission.
- Harsh or noisy natural to reverse shifts All models equipped with RFE transmission.
- Harsh 4-3 downshifts. This condition happens when there is no throttle applied and the vehicle is coasting down. All models equipped with RFE transmission.
- Harsh 1-2 upshifts. This condition happens under moderate or heavy throttle conditions All models equipped with RFE transmission.
- Engine knock condition. This condition could happen when a wide open throttle (WOT) event is performed or cruising at 5400 RPM or above All models equipped with RFE transmission.
- Hard start or long crank condition at 0° F (-17° C). all 5.7L DS and DJ models equipped with RFE transmission.
Reprogramming the PCM will correct the DTC conditions listed above.
Using a Scan Tool (wiTECH) with the appropriate Diagnostic Procedures available in TechCONNECT, verify no DTC’s are set. If DTC’s are present other then the ones listed above record them on the repair order and repair as necessary before proceeding further with this bulletin.
If the customer describes the symptom or if the technician finds the DTC, perform the Repair Procedure.
|1||04275086AD||Label, Authorized Modification|
NOTE: If this flash process is interrupted/aborted, the flash should be restarted.
- Reprogram the PCM with the latest software. Follow the detailed service procedures available in DealerCONNECT/TECHCONNECT, Refer To 8 – Electrical/Electronic Control Modules/Powertrain Control Module – Standard Procedure PCM/ECM Programming.
- After PCM reprogramming, the following must be performed,Clear any DTC’s that may have been set in other modules due to reprogramming. The wiTECH application will automatically present all DTCs after the flash and allow the tech to clear them.
- Type the necessary information on the “Authorized Modification Label” and attach it near the VECI label.
Reimbursable within the provisions of the warranty.

Chrysler J2534 Application Overview
The Chrysler J2534 System is a combination of the J2534 Application (2010 and newer Model Year Support) and the Chrysler J2534 Flash Application (2009-1996 Model Year Support). J2534 aftermarket users are required and responsible for installing the J2534 device driver provided by the device manufacturer. If you need support installing the device driver software contact the device manufacturer. See the related article “Chrysler J2534 Manual” for additional information. Chrysler J2534 application provides below capabilities:
|The Chrysler J2534 Flash Application:|
|Application Usage and Support|
Chrysler Recommended J2534 Devices
|J2534 Device||Firmware Version|
|CTC Vehicle Box *||1.9|
|Blue Streak -2534 Global Programmer||2.10|
|Actia I+ME Passthru||2.07|
* Chrysler recommends the CTC Vehicle Box Device for Chrysler SCI ECU reprogramming. SCI reprogramming is used on most PCMs and TCMs prior to the introduction of CAN bus vehicles which began in 2004 (Durango).

Additional Information and Known Issues / Concerns:
If you are reprogramming the 5.9L diesel engine controller on the 1996-2008 Dodge RAM vehicle, it is necessary to also reprogram the VIN after the ECU has been flashed. To write the VIN to the ECU, you may use aftermarket software support, or use an OEM FCA US LLC scan tool (DRBIII or StarSCAN). For more information, see the FCA US LLC Scan Tool Lease Options section.
- 1996-2009 ALL PCMs
If you are REPLACING a PCM or ECM and the vehicle is equipped with a theft deterrent system (Sentry Key), it must be initialized to properly function with the Anti Theft module. You also need to reprogram the VIN when replacing a PCM or ECM. To write the VIN to the ECU and initialize the PCM to work with the theft deterrent system, you may use aftermarket software support, or use an OEM FCA US LLC scan tool (DRBIII or StarSCAN). For more information, see the FCA US LLC Scan Tool Lease Options section.
FCA US LLC Scan Tool Lease Options:
- For 2009 model year vehicles and prior, it may be necessary to use either a DRBIII or a StarSCAN to perform function required after ECU replacement. To lease the DRBIII call 1-586-532-8400 or click here.
- Beginning with 2010 MY, function required to replace an ECU will be supported via the J2534 application.
