5. Configuración
5.1. Conexión ao vehículo
- Locate the vehicle's Diagnostic Link Connector (DLC). For 12V vehicles, this is typically a 16-pin OBD2 port. For heavy-duty 24V vehicles, it will be a 6-pin or 9-pin connector.
- If diagnosing a heavy-duty vehicle, attach the appropriate 6-pin or 9-pin adapter to the HD10's main cable, then connect to the vehicle's DLC. For 12V vehicles, connect the standard OBD2 connector directly.
- Ensure the connection is secure. The device will power on automatically once connected to the vehicle's power supply.
