1. Preparation

Gather necessary tools: OBD-II scanner, socket set, and wrench.
Ensure the vehicle is parked on a flat surface with the ignition turned off.

2. Using an OBD-II Scanner

Locate the OBD-II port under the dashboard on the driver's side.
Plug in the OBD-II scanner.
Turn the vehicle's ignition to the "ON" position (do not start the engine).
Follow the scanner prompts to read and note any trouble codes.
If necessary, clear the codes using the scanner's clear function.

3. Disconnecting the Battery

Open the hood and locate the battery.
Using a socket or wrench, loosen the negative (-) battery terminal clamp.
