Solution

1. Preparation

Gather tools and safety gear: gloves and safety glasses.
Ensure the vehicle is in park or neutral, and the parking brake is engaged.

2. Battery Inspection

Disconnect Battery
- Use a socket wrench to disconnect the negative terminal first, then the positive terminal.
Clean Battery Terminals
- Use a wire brush to clean any corrosion on the battery terminals and cable ends.
Reattach Battery
- Reconnect the positive terminal first, then the negative terminal. Ensure connections are tight.

3. Starter Motor Test

Access Starter Motor
- Raise the vehicle safely using jack stands and remove any necessary covers.
Test Starter Functionality
- Using a remote starter switch, connect to the starter motor's terminals. If it engages, the starter is functional.
Inspect Wiring
- Check the wiring to the starter for any signs of damage or loose connections.

4. Replace Battery (if necessary)

Remove Old Battery
- Disconnect the terminals again, remove the hold-down bracket, and lift the battery out.
Install New Battery
- Place the new battery in the tray and secure it with the hold-down bracket. Connect the terminals (positive first).

5. Final Checks

Reconnect Ignition System
- Ensure all electrical connectors are secure.
Test Start the Vehicle
- Attempt to start the vehicle and monitor for any unusual sounds.
