OVERVIEW:
This bulletin involves selectively erasing and reprogramming the Powertrain Control Module (PCM) with new software.
MODELS:
2006 - 2007 (RS) Town & Country/Caravan (Includes International Markets)
2006 - 2007 (RG) Chrysler Voyager (International Markets)
NOTE:
This bulletin applies to RS models built prior to October 2, 2006 with an R in VIN position 11 (MDH 1002XX), October 9, 2006 with a B in VIN position 11 (MDH 1009XX), RG models built prior to October 2, 2006 (MDH 1002XX) equipped with a 3.3L or 3.8L engine (Sales Code EGA, or EGH), **or 2007 RS models built prior to February 24, 2007 (MDH0224XX) with a 2.4L engine (Sales Code EDZ).**
SYMPTOM/CONDITION:
The vehicle operator may experience MIL illumination with no other symptoms. This may occur intermittently and be difficult to duplicate. When the technician evaluates the vehicle, diagnosis may lead to incorrectly replacing the fuel pump/sending unit module.
DIAGNOSIS:
Using a Scan Tool (DRBIII(R)) with the appropriate Diagnostic Procedures available in TechCONNECT, verify all engine systems are functioning as designed. If DTC's other than P0461 are present record them on the repair order and repair as necessary before proceeding further with this bulletin.
If P0461 - Fuel Level Sensor # 1 Performance was recorded, perform the Repair Procedure.
PARTS REQUIRED:
SPECIAL TOOLS / EQUIPMENT REQUIRED:
NOTE:
An updated J1962 cable has been released. This cable has a red colored connector at the DRBIII(R) connection. Use this cable whenever a flash is being performed.
REPAIR PROCEDURE USING DRBIII(R) AND DOWNLOADING THE FLASH FILE FROM DealerCONNECT > Tech TOOLS:
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 - 2007 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 and install a battery charger. Using a voltmeter, verify that the charging rate provides 13.2 - 13.5 volts. Set the battery charger to continuous charge. Do not allow the charger to time out during the flash process. Remove the charger from the battery when the flash process is complete.
NOTE:
Do not allow the charging voltage to climb above 13.5 volts during the flash process.
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.
NOTE:
Due to the PCM programming procedure, a DTC may be set in other modules 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.
13. Reset the "Pinion Factor" as necessary.
14. Perform the transmission Quick Learn Procedure as necessary.
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 (Fig. 1).
