2. Scan for Codes

• Connect the OBD-II scanner to the vehicle's diagnostic port, usually located under the dashboard near the driver's seat.
• Turn the ignition to the "On" position without starting the engine.
• Follow the scanner's instructions to read the error codes.

3. Clear Error Codes

• Confirm the action and wait for the scanner to indicate that the codes have been successfully cleared.

4. Battery Disconnection (Optional)

• If additional reset is needed, disconnect the negative terminal of the battery using a socket wrench.
• Wait for about 5-10 minutes to allow the vehicle's computer to reset.
• Reconnect the negative terminal and ensure it is secured properly.
