Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, wrench set, jumper cables
Disconnect the negative battery terminal to ensure safety.

2. Battery Inspection and Replacement

Check Battery Voltage
- Reconnect the battery and measure voltage with a multimeter.
- If below 12.4 volts, charge the battery or replace it if it fails to hold a charge.
Clean Battery Terminals
- Use a wire brush to clean any corrosion from battery terminals and cable connectors.
- Reconnect battery terminals securely.

3. Starter Motor Inspection

Locate the Starter Motor
- Typically located near the engine block underneath the vehicle.
Test the Starter
- Use jumper cables to connect directly to the starter motor terminals.
- If the starter engages and the engine cranks, the starter is functional; if not, it may need replacement.

4. Replace Faulty Components

Replace Battery (if necessary)
