time of engine start up. This condition may affect all vehicles listed above, except Durango
(HB) and Ram Truck (DR).

P1521 - Incorrect Engine Oil Type. This DTC may set in high ambient temperature
conditions when the correct oil type (viscosity) is being used in the engine.

TechCONNECT, verify all engine systems are functioning as designed. If DTC's are
present record them on the repair order and repair as necessary before proceeding further
with this bulletin.

Repair Procedure: 

USING THE INTERNET TO RETRIEVE THE FLASH FILE:

NOTE: Before performing this Repair Procedure, the operating system in the
StarSCAN® must be programmed with software release level 6.06 or higher.
The software release level is visible in the blue header at the top of the
StarSCAN® screen.

NOTE: The StarSCAN® diagnostic scan tool fully supports Internet connectivity.
However, to take advantage of this feature you must first configure the
StarSCAN® 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® for the dealer's network refer to either:
“DealerCONNECT > Service > StarSCAN and StarMOBILE tools > Online
Documentation”, or refer to the StarSCAN® Quick Start Networking Guide.
The StarSCAN® Quick Start Networking Guide is also available on the
www.dcctools.com 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® ethernet cable to the StarSCAN® and the dealer'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 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 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.

NOTE: Due to the ECU 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 ECM and/or TCM.

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