how to reset the check engine light on a Volvo XC90

Solution

1. Preparation

• Gather all required tools and ensure the vehicle is parked on a level surface with the engine off.
• Make sure you have an OBD-II scanner ready for use.

2. Connect the OBD-II Scanner

• Locate the OBD-II port beneath the dashboard on the driver's side.
• Plug the OBD-II scanner into the port.
• Turn the ignition key to the "On" position without starting the engine.

3. Read and Clear Codes

• Follow the instructions on the OBD-II scanner to read any stored trouble codes.
• Once noted, select the option to "Clear Codes" or "Erase Codes" on the scanner.
• Confirm the action when prompted on the scanner screen.

4. Disconnect the Scanner

• After clearing the codes, safely unplug the OBD-II scanner from the port.
• Turn off the ignition and wait a few seconds before restarting the vehicle.

5. Verify Reset

• Start the engine and observe if the check engine light remains off.
• If the light is still illuminated, repeat the scanning process to ensure no new codes have appeared.
