4. Podešavanje
The Riokko YM119 scanner is designed for quick and easy setup. No batteries are required as it draws power directly from the vehicle's OBDII port.
Povezivanje skenera:
- Locate the vehicle's 16-pin Data Link Connector (DLC). The DLC is usually located under the dashboard on the driver's side. Refer to your vehicle's service manual for the exact location if you cannot find it.
- Turn the vehicle's ignition to the OFF position.
- Firmly plug the scanner's OBDII connector into the vehicle's DLC.
- Turn the vehicle's ignition to the ON position (engine off). The scanner will automatically power on and display the main menu.
Note: If the scanner does not power on, ensure the connection is secure and check the vehicle's fuse for the OBDII port.
5. Uputstvo za upotrebu
Once the scanner is connected and powered on, you can navigate through the main menu using the UP, DOWN, LEFT, RIGHT, OK, and EXIT buttons.
