NUMBER: 18-032-10GROUP: Vehicle Performance
DATE: December 10, 2010
THIS BULLETIN SUPERSEDES SERVICE BULLETIN 18-022-09, DATED JULY 31, 2009 WHICH SHOULD BE REMOVED FROM YOUR FILES. ALL REVISIONS ARE HIGHLIGHTED WITH **ASTERISKS** AND INCLUDE THE ADDITION OF NAS EMISSION CODE FOR 2003 AN VEHICLES.
WHENEVER A MODULE IS REPROGRAMMED, THE SOFTWARE IN THE DRBIII(R); MUST BE PROGRAMMED WITH THE LATEST REVISION LEVEL AVAILABLE.
SUBJECT:
Flash: PCM To Allow The Generic Scan Tool To Properly Report Catalyst Monitor
OVERVIEW:
This bulletin involves selectively erasing and reprogramming the Powertrain Control Module (PCM) with new software.
MODELS:
2003 (DN) Durango
2003 (DR) Ram Truck
2003 (AN) Dakota
NOTE:
This bulletin applies to DN or DR vehicles equipped with a 4.7L engine (sales code EVA) and California Emissions (sales code NAE).
NOTE:
This bulletin applies to AN vehicles equipped with a 4.7L engine (sales code EVA) and California emissions or U.S 50 State Emissions (sales code NAE **or NAS**).
SYMPTOM/CONDITION:
The Customer may be rejected or failed at an I/M Test Station because the Generic Scan Tool does not show Catalyst Monitor as "supported".
Flashing the PCM will allow the Generic Scan Tool to properly report that the Catalyst Monitor is a supported monitor on these packages.
DIAGNOSIS:
Using a Scan Tool (DRBIII(R)) with the appropriate Diagnostic Procedures available in TechCONNECT, 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 Repair Procedure.
PARTS REQUIRED:
SPECIAL TOOLS / EQUIPMENT REQUIRED:
REPAIR PROCEDURE FOR DOMESTIC VEHICLES USING DRBIII(R) AND DOWNLOADING THE FLASH FILE FROM DealerCONNECT:
NOTE:
Whenever a module is reprogrammed, 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 process should be restarted and then follow the directions on the DRBIII(R).
1. Before beginning the flash procedure, remove any old flash 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 - 2005 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 flash file.
5. Select the flash file.
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 that the charging rate provides approximately 13.5 volts.
11. Connect the DRBIII(R) to the vehicle.
12. Download the flash file 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, proceed to the next step.
13. Reset the "Pinion Factor" as necessary.
14. Perform the transmission Quick Learn Procedure as necessary.
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.
15. Type the necessary information on the "Authorized Modification Label" p/n 04275086AB and attach near the VECI label.
REPAIR PROCEDURE FOR EXPORT VEHICLES USING DRBIII(R) AND DOWNLOADING THE FLASH FILE FROM DealerCONNECT:
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 - 2006 Diagnostics"
c. "All (Except Below)"
d. "Engine"
e. "Module Display"
f. Record the "PCM part # " on the repair order for later reference.

3. Log into DealerCONNECT. Proceed to: Service / Repair - Flash.
4. Select vehicle Year, Model, and Engine (YME). Then select the "Submit button at the bottom of the screen.
5. Compare the calibration part number available for flash reprogramming to the module part number recorded earlier. Select the new calibration if applicable.
6. Download the new calibration to the PC.
7. Using the "DRBIII - WINFLASH II" application on the PC, download the flash calibration file to the DRBIII(R) from the PC.
8. Disconnect the DRBIII(R) from the PC and NULL modem cable.
