SUBJECT:
Flash: MIL Illumination with DTC's P0139, P0159, P0420, or P0430
OVERVIEW:
This bulletin involves reprogramming the Powertrain Control Module (PCM) with new software.
MODELS:
2007 (CS) Pacifica
NOTE:
This bulletin applies to models built with a 4.0L Engine (Sales Codes EGQ). built on or before December 15, 2006 (MDH1215XX).
SYMPTOM/CONDITION:
Some customers may experience MIL Illumination with no performance issues noted. MIL illumination can be intermittent and not coincide with any vehicle operating parameters.
Further investigation by the technician may find the following DTC's:
1. P0139-02 Sensor 112510w Response.
2. P0159-02 Sensor 2/2 Slow Response.
3. P0420-Catalyst Efficiency (Bank 1)
4. P0430-Catalyst Efficiency (Bank 2)
DIAGNOSIS:
Using a Scan Tool (StarSCAN(R)) with the appropriate Diagnostic Procedures available in DealerCONNECT > TechCONNECT, verify all engine/transmission systems are functioning as designed. If DTC's other than those listed above are present record them on the repair order and repair as necessary before proceeding further with this bulletin.
Perform Diagnostic Procedures available in DealerCONNECT > TechCONNECT to verify related mechanical systems are working as designed:
^ EXHAUST SYSTEM LEAK
^ CATALYTIC CONVERTER
^ ENGINE MECHANICAL CONDITION
^ AGING OR CONTAMINATED 02 SENSOR
If any system is found to be causing the DTC's repair the system before proceeding. If all systems are operating as designed perform the Repair Procedure.

FLASH REPAIR PROCEDURE - USING THE INTERNET TO RETRIEVE THE FLASH FILE:
NOTE:
When performing this Repair Procedure, the software release level in the StarSCAN(R); must be programmed with 7.03 SP 1 level software or higher.
The software release level is visible in the blue header at the top of the StarSCAN(R) screen.
NOTE:
The StarSCAN(R) diagnostic scan tool fully supports Internet connectivity. However, to take advantage of this feature you must first configure the StarSCAN(R) for your dealership's network. Make sure the StarSCAN� is configured to the dealership's network before proceeding. For instruction on setting up your StarSCAN(R) for the dealer's network refer to either:
"DealerCONNECT > Service > StarSCAN and StarMOBILE tools > Online Documentation", or refer to the StarSCAN(R) Quick Start Networking Guide. The StarSCAN(R) Quick Start Networking Guide is also available on the website under the "Download Center".
NOTE:
If this flash process is interrupted/aborted, the flash should be restarted.
1. Install a battery charger and verify that the charging rate provides approximately 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.
2. Connect the CH9410 StarSCAN(R) ethernet cable to the StarSCAN(R) and the dealer's network drop.
3. Connect the CH9404 StarSCAN(R) vehicle cable to the StarSCAN(R) and the vehicle.
4. Power ON the StarSCAN(R).
5. Retrieve the old PCM part number. Using the StarSCAN(R) at the "Home" screen:
a. Select "ECU View"
b. Touch the screen to highlight the PCM in the list of modules.
c. Select "More Options"
d. Select "ECU Flash"
e. Record the part number at the top of the "Flash PCM" screen for later reference.
f. Select "Browse for New File". Follow the on screen instructions.
g. Select "Download to Scantool".
h. Select "Close" after the download is complete, then select "Back".
i. Highlight the listed calibration.
j. Select "Update Controller". Follow on screen instructions.
k. When the update is complete, select "OK".
l. Verify the part number at the top of the "Flash PCM" screen has updated to the new part number.
NOTE:
Due to the PCM programming procedure, a DTC may be set in other modules (TCM, BCM, MIC, SKREEM, etc.) within the vehicle, if so equipped. Some DTC's may cause the MIL to illuminate. From the "Home" screen select "System View". Then select "All DTCs". Press "Clear All Stored DTCs" if there are any DTCs shown on the list.
NOTE:
The following step is required by law when reprogramming a PCM and/or TCM.
6. Type the necessary information on the "Authorized Modification Label" p/n 04275086AB and attach near the VECI label (Fig. 1).
