02 How To Use
2.1 Data Link Connector (DLC) Location
The DLC (Data Link Connector or Diagnostic Link Connector) is typically a 16-pin connector where diagnostic code readers interface with the vehicle's onboard computer. The DLC is usually located 12 inches from the center of the instrument panel (dash), under or around the driver's side for most vehicles. If the Data Link Connector is not located under the dashboard, a label should be there indicating its location. For some Asian and European vehicles, the DLC is located behind the ashtray, and the ashtray must be removed to access the connector. If the DLC cannot be found, refer to the vehicle's service manual for the location.

[Note] Turn on the ignition of the vehicle. The voltage range of the device should be 9-18V, and the throttle should be in the closed position.
