How to Use This Code Reader

Before starting diagnosis, please ensure:

1. The ignition switch is turned to the ON position.
2. The vehicle's engine is off.
3. The vehicle battery voltage is between 10-14 volts.
4. The scanner is correctly connected to the vehicle.

Important: Do not connect or disconnect the code reader while the ignition is on or the engine is running.

Connecting the Device:

Locate the OBDII interface port on your vehicle (typically under the dashboard). Insert the OBDII Cable connector from the Foxwell reader into this port. The OBDII Connector has 16 pins with specific functions, including power, ground, and communication lines like CAN, ISO 9141-2, and SAE J1850.

Navigating and Reading Codes:
