Solution

1. Preparation

Gather tools: multimeter, socket set, wrench set, jumper cables, and safety glasses.
Ensure the vehicle is in "Park" (automatic) or "Neutral" (manual).

2. Battery Inspection

Disconnect the Battery: Use a wrench to disconnect the negative terminal first, followed by the positive terminal.
Clean the Terminals: If corrosion is present, clean the battery terminals and cable connectors with a wire brush and a mixture of baking soda and water.
Reconnect the Battery: Attach the positive terminal first, followed by the negative terminal, and ensure they are tight.

3. Starter Motor Testing

Locate the Starter Motor: It is typically located near the transmission on the driver's side.
Inspect the Connections: Check both power and ground connections to the starter motor for tightness.
Test Starter Functionality:
- If accessible, use a jumper wire to momentarily connect the starter’s positive terminal to the battery to see if it engages.
- If it does not engage, the starter may need replacement.

4. Battery Replacement (if necessary)

Remove the Old Battery: Disconnect the negative terminal first, followed by the positive terminal. Remove any securing brackets and lift the battery out.
Install New Battery: Place the new battery in the tray, secure it with brackets, and connect the positive terminal first, then the negative terminal.
Test Start the Vehicle: Attempt to start the vehicle to check if the issue is resolved.
