REPAIR PROCEDURE - USING StarSCAN AND THE INTERNET TO RETRIEVE THE FLASH FILE:

NOTE:
Before performing this Repair Procedure, the operating software in the StarSCAN(R) must be programmed with software release level 8.02 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, in order to take advantage of this feature you must first configure the StarSCAN(R) for your dealership's network. For instruction on setting up your StarSCAN(R) for the dealer's network; refer to the StarSCAN(R) Quick Start Networking Guide available on the website under the "download center".

NOTE:
If this flash process is interrupted/aborted, the flash should be restarted.

1. 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.

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 ECU 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".

k. When the update is complete, select "OK".

6. Perform the Quick Learn function, found in the StarSCAN(R) Misc Function Menu.

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 PCM and/or TCM.





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