Solution

1. Preparation

Gather necessary tools: wrench for battery terminal, safety glasses.
Ensure the vehicle is parked on a flat surface and in "Park" or neutral with the parking brake engaged.

2. Disconnect the Battery

Using a wrench, loosen the bolt on the negative battery terminal (marked with a minus sign).
Carefully remove the negative terminal from the battery post, ensuring it does not touch the battery during the process.

3. Discharge Electrical System

With the negative terminal disconnected, press and hold the brake pedal for 15 seconds. This discharges any residual power in the vehicle's electrical system.

4. Reconnect the Battery

Reattach the negative battery terminal to the battery post.
Tighten the bolt securely to ensure a good connection, but do not overtighten to avoid damaging the terminal.

5. Start the Vehicle

Turn the ignition to the "On" position and then start the engine.
Observe the dashboard for warning lights, particularly the check engine light.
