GROUP: Vehicle Performance

DATE: March 2, 2004

THIS BULLETIN IS BEING PROVIDED IN ADVANCE. THE SOFTWARE FOR DR VEHICLES WILL BE AVAILABLE ON TechCONNECT MARCH 2, 2004. THE SOFTWARE FOR HB VEHICLES WILL BE AVAILABLE ON StarSCAN(TM) SOFTWARE UPDATE CD RELEASE 4.06, MARCH 15, 2004.

SUBJECT:
Flash: MIL Illumination Diagnostic Trouble Codes (DTC's) P0403, P0404, P0405, P0406

OVERVIEW:
This bulletin involves selectively erasing and reprogramming the Powertrain Control Module (PCM) with new software.

MODELS:

2004 (DR) Ram Truck

2004 (HB) Durango

NOTE:
This bulletin applies to DR and HB vehicles equipped with a 5.7L engine (sales code EZA) built on or before February 29, 2004 (MDH 0229XX).

SYMPTOM/CONDITION:

The vehicle operator may experience a MIL illumination. Further diagnosis may determine that the MIL was caused by one or more of the following DTC's:

P0403-EGR CONTROL CIRCUIT

P0404-EGR POSITION SENSOR PERFORMANCE

P0405-EGR POSITION SENSOR LOW

P0406-EGR POSITION SENSOR HIGH

DIAGNOSIS:

Using a Scan Tool (DRBIII(R) with TechCONNECT or the appropriate Diagnostic Procedures Manual, verify all engine systems are functioning as designed. If DTCs are present record them on the repair order and repair as necessary before proceeding further with this bulletin.

If the vehicle operator describes or experiences the Symptom/Condition, perform the appropriate Repair Procedure.

NOTE:
There are three separate Repair Procedures. One for DR vehicles and two for HB vehicles.

NOTE:
There are two methods to download flash files to StarSCAN. The first method is to download the flash files from the StarSCAN Software Update CD. The second method (NEW) is to download the flash files to the StarSCAN from the internet.





SPECIAL TOOLS/EQUIPMENT REQUIRED:

REPAIR PROCEDURE FOR DR VEHICLES:

NOTE:
Whenever a controller is programmed, the software in the DRBIII(R) must be programmed with the latest revision level available.

NOTE:
If this flash process is interrupted/aborted, the flash should be restarted and then follow the directions on the DRBIII(R).

1. Before beginning the reprogramming procedure, remove any old flash reprogramming files from the DRBIII(R) memory. To clear the memory from the MAIN MENU:

a. Simultaneously press the "MORE" and "YES" keys.

b. A screen will appear requesting a "COLD BOOT".

c. Follow the on screen instructions by selecting the "F4" key.

d. When the DRBIII(R) reboots to the MAIN MENU, proceed to (STEP # 2)

2. With the ignition switch in the "RUN" position, determine the original part number of the PCM currently in the vehicle. Using the DRBIII(R) select:

a. "DRBIII(R) Standalone"

b. "1998 - 2004 Diagnostics"

c. "All (Except Below)"

d. "Engine"

e. "Module Display"

f. Record the "PCM part # " on the repair order for later reference.

3. Connect the DRBIII(R) to TechCONNECT. Open TechTOOLS and verify that the "DRBIII(R) Status: Connected" message is in the upper right corner of the TechTOOLS screen.

4. Enter the "PCM part # " recorded in (STEP # 2) in the "Parts Criteria" area and select "Show Updates". TechTOOLS will populate the appropriate calibration.

5. Select the calibration.

6. Select the "DRBIII" radio button which is next to the "Download/Update" button.

7. Select the "Download/Update" button.

8. Monitor the "Flash Download/Update Progress" window on the TechCONNECT and follow the instructions on TechCONNECT. When the flash process is complete, proceed to (STEP # 9).

9. Disconnect the DRBIII(R) from TechCONNECT.

10. Open the hood, install a battery charger and verify battery state is above 12.5 volts.

11. Connect the DRBIII(R) to the vehicle.

12. Download the flash from the DRBIII(R) to the vehicle. Using the DRBIII(R) select:

a. "Vehicle Flash"

b. Follow the directions on the DRBIII(R) screen. When the flash process is complete, select OK.

NOTE:
Due to the PCM programming procedure, a DTC may be set in other modules (TCM, BCM, MIC, SKIM, etc.) within the vehicle, if so equipped. Some DTC's may cause the MIL to Illuminate. Check all modules using "Module Scan", record the DTC's, and erase these DTC's prior to returning the vehicle to the customer. Erase any DTC's in the PCM only after all other modules have had their DTC's erased.

NOTE:
The following step is required by law.





13. Type the necessary information on the "Authorized Modification Label" p/n 04275086AB and attach near the VECI label (Fig. 1).
