How to Diagnose and Upgrade ECU for Reimported Vehicles

1. After launching GDS Smart, check the VCI connection status (Wi-Fi Direct, Bluetooth, wired) and then enter [Vehicle Selection].

2. Select the region menu at the top left to choose the export country destination of the vehicle for diagnosis/upgrade. 

Example: 
   A)If a vehicle was manufactured in Korea and sold to a consumer in the USA,
      select USA for diagnosis/upgrade.
   B)If a vehicle was manufactured in USA and sold to a consumer in the USA,
      select USA for diagnosis/upgrade.

3. Select the vehicle model, then choose the year and engine type, and manually enter the VIN. (If AUTO VIN is available, you can use AUTO VIN to enter the model, year, and engine type.)

4. A diagnostic number (VDN) will be generated. After confirming that the vehicle information (model, year, engine type) has been correctly selected, proceed to the ECU Upgrade menu. 

5. You can enter Manual Mode to perform the ECU upgrade. 

If you cannot find the ECU upgrade you wish to perform, please contact us via gitauto.zendesk.com or submit an inquiry using the Inquiry button at the top right of the screen. 
When making an inquiry, please be sure to provide the vehicle model, year, engine type, and VIN.
