Solution

1. Preparation

Tools Required: Safety gloves, multimeter, battery terminal cleaner, wrench set.
Safety Warning: Always wear safety gloves and eye protection when handling batteries. Ensure the vehicle is in park with the parking brake engaged.

2. Remove Battery

Disconnect the negative terminal first using a wrench to avoid short circuits.
Then, disconnect the positive terminal.
Remove any hold-down brackets securing the battery.
Carefully lift the battery out of the vehicle.

3. Clean Battery Terminals

Use a battery terminal cleaner or a wire brush to clean any corrosion from the terminals and connectors.
Ensure all connections are shiny and free from dirt.

4. Replace Battery (if necessary)

If the battery is confirmed dead or cannot hold a charge after testing, replace it with a new one.
Ensure the new battery matches the specifications (size, cold cranking amps) of the original.

5. Reinstall Battery

Place the new or reconditioned battery into the battery tray.
Secure it with the hold-down brackets.
Connect the positive terminal first, followed by the negative terminal.

6. Test the System

Start the vehicle to ensure it cranks and operates correctly.
Monitor the dashboard to ensure all indicator lights function properly.
