USING THE INTERNET TO RETRIEVE THE FLASH FILE:

NOTE: The StarSCAN® diagnostic scan tool fully supports Internet connectivity.
However, in order to take advantage of this feature you must first configure
the StarSCAN® for your dealership's network. For instruction on setting up
your StarSCAN® for the dealer's network; refer to the StarSCAN® Quick Start
Networking Guide 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. Open the hood, install a battery charger and verify that the charging rate provides
approximately 13.5 volts.

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 ECU part number. Using the StarSCAN® at the “Home” screen:

NOTE: If the ECM is not operational, the “ECM part number” can be obtained from
the label on the controller. If the label on the controller is not legible, record
the “Reference No.” for use later. The “Reference No.” is located in the
Reference No. box at the top, center of the Engine Data Plate (Fig. 1). Do not
use the reference number shown in the figure. The Engine Data Plate is
located on the intake side of the breather cover or affixed to the APPS

Details of flash procedure are not posted - The reprogramming procedure requires access to software and equipment that most owners do not have. The very long and involved programming procedure will not be posted here. To see the specific instructions, you can obtain or view a copy of this TSB at your dealership. If you can not find a helpful dealer, contact me to obtain the complete bulletin.

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.

Type the necessary information on the “Authorized Modification Label” p/n 04275086AB
and attach near the VECI label (Fig. 2).
