Gather necessary tools: OBD-II scanner, socket set, and possibly a wrench for battery terminals.
Ensure vehicle is parked on a level surface with the engine off and the keys removed from the ignition.

2. Use an OBD-II Scanner

Plug the OBD-II scanner into the OBD-II port located under the dashboard near the steering column.
Turn the vehicle's ignition to the "On" position without starting the engine.
Follow the scanner's prompts to read and clear error codes.

Open the hood and locate the battery.
Using a socket or wrench, disconnect the negative (-) battery terminal first and then the positive (+) terminal.
