If it is the first time you have used this tool, you need to make some system settings and keep the diagnostic software synchronized with the latest version.
Follow the steps below to proceed.
Preparation

- Locate vehicle’s DLC: It provides standard 16 pins and is generally located on the driver’s side, about 12 inches away from the center of the dashboard. See Figure DLC Location. If DLC is not equipped under the dashboard, a label indicating its position will be given. In case no DLC is found, please refer to the Automobile Repair Manual.

Start Diagnostics
AutoDetect and manual diagnosis are supported. If the AutoDetect fails, you can choose to input the VIN manually or exit the AutoDetect session to switch to manual diagnosis mode.
Note
If “Automatic detection on connect” in “Settings” is set as ON, this step can be ignored.
Input the VIN, and tap “OK”, the system will automatically identify the vehicle model. If the vehicle VIN is successfully decoded, it will perform auto-diagnosis until a diagnostic report is automatically output.
Note
The most recognizable location for VIN is in the top left corner of the vehicle’s dashboard. Other locations include the driver’s door or post, and the firewall under the hood.
