ROM ID Information Table:
To verify the vehicle is affected, be sure to check the Calibration Identification of the vehicles ECM ROM ID and reference the Information Table as necessary.
1. Connect the power supply cable to the GDS tool or to the diagnostic terminal with the GDS docked.
*NOTICE
If attempting to perform the ECM upgrade with the power supply cable disconnected from the GDS tool, be sure to check that the GDS tool is fully charged before ECM upgrade. If the GDS tool is not fully charged, failure to perform the ECM upgrade may occur. Therefore, it is strongly recommended that the power supply be connected to the GDS tool.
2. Connect the USB cable between the VCI and the GDS tool.
*NOTICE
When performing the ECM upgrade using the GDS tool, wireless communication between the VCI and GDS tool is not available. Therefore, be sure to connect the USB cable between the VCI and the GDS tool.
3. Connect the Main 16-pin DLC cable (GHDM - 241000) to the VCI.
4. Connect the Main 16-pin DLC cable (GHDM - 241000) between the VCI and the OBD-II connector, located under the driver's side of the instrument panel.
5. With the ignition key ON (DO NOT start the engine!), turn ON the VCI and GDS tool. Access the GDS vehicle identification number (VIN) screen and configure the vehicle using the VIN AUTO DETECT Function.
6. Once back at the GDS Main Screen, select ECU Upgrade from the bottom right-hand corner. Next select Auto Mode, and then Engine. Perform the ECM upgrade in accordance with normal GDS tool ECM upgrade procedures.
*NOTICE
Do NOT attempt to perform a Manual Mode upgrade unless Auto Mode fails. Always follow the instructions given on the GDS tool in either Auto or Manual mode. See table for Manual Mode passwords.

7. When the GDS tool reports that the ECM upgrade has been successfully completed, click OK, turn OFF the ignition key, and wait at least 10 seconds before attempting to start the engine.
8. Check for Diagnostic Trouble Codes using the GDS and erase any DTCs stored such as EPS, ESC, and TPMS. Due to CAN BUS multiple DTCs maybe set during reprogramming.
9. Start the engine to confirm proper operation of the vehicle.
