This bulletin applies to 2007 Dodge Durango and Aspen vehicles equipped with the 4.7L engine. Some vehicles may exhibit a MIL illumination due to DTC P013A/P013C (downstream oxygen sensor(s) slow response – rich to lean). Erasing and reprogramming the PCM module with new software is recommended.
Using a scan tool (StarSCAN) with the appropriate diagnostic procedures available in TechCONNECT, verify that all engine systems are functioning as designed. If other DTCs are present, record and repair as needed before proceeding.
When performing this repair procedure, the software release level in the StarSCAN must be programmed with 7.02 SP1 level software or higher. The software release level is visible in the blue header at the top of the StarSCAN screen. Make sure that the StarSCAN is configured to the dealrship’s network before proceeding if using Internet connectivity.
1. Install a battery charger and set the charging rate at approximately 13.5 volts on continuous charge.
2. Connect the CH9410 StarSCAN Ethernet cable to the StarSCAN and the dealership’s network drop.
3, Connect the CH9404 StarSCAN vehicle cable to the StarSCAN and the vehicle.
4. Power ON the StarSCAN.
5. Retrieve the old PCM part number. Using the StarSCAN 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 Scan Tool.”
h. Select “Close” after the download is complete, then select “Back.”
i .Highlight the listed PCM calibration.
j. Select “Update Controller.” Follow the on screen instructions.
k. When the PCM 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.
Due to the PCM programming procedure, a DTC may be set in other modules. Some DTCs 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.
Type all necessary information on an authorized modification label P/N 04275086AB and attach near the VECI label.
