Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, screwdriver set.
Ensure the vehicle is in park (automatic) or neutral (manual) and the parking brake is engaged.

2. Battery Inspection and Replacement

Disconnect the Battery
- Use a socket wrench to remove the negative (-) terminal first, followed by the positive (+) terminal.
- Safety Warning: Always disconnect the battery before working on electrical systems.
Clean Terminals
- Inspect the battery terminals for corrosion. Clean with a mixture of baking soda and water, and scrub with a wire brush.
- Rinse with water and dry thoroughly.
Test or Replace Battery
- If the voltage is below 12.4 volts, charge the battery. If it does not hold a charge, replace it with a new one of the same specifications.

3. Starter Motor Inspection

Access the Starter
- Locate the starter motor, typically found near the transmission.
- Remove any components obstructing access (i.e., engine covers).
Check Connections
- Inspect electrical connections to the starter. Tighten any loose wires and ensure they are free of corrosion.
Test Starter Operation
- Use a multimeter to check the voltage at the starter while attempting to start the vehicle.
- If the starter engages but does not turn over the engine, consider replacing the starter.

4. Reassemble and Test

Reattach Battery
- Connect the positive (+) terminal first, then the negative (-) terminal.
- Ensure connections are tight.
Start the Vehicle
- Turn the ignition key to test if the issue is resolved. Listen for any abnormal noises.
