Solution

1. Preparation

Gather required tools: multimeter, socket set, wrench set, OBD-II scanner, battery terminal cleaner, and safety gloves.
Ensure the vehicle is in park (or neutral) and turn off all electrical accessories.

2. Battery Inspection

2.1. Clean Battery Terminals
- Disconnect the negative (-) terminal first, then the positive (+) terminal.
- Use a battery terminal cleaner to remove corrosion from both terminals.
2.2. Test Battery Voltage
- Connect the multimeter leads to the battery terminals (red to positive, black to negative).
- If the voltage is below 12.4 volts, proceed to replace the battery.

3. Battery Replacement (if needed)

3.1. Remove Old Battery
- Disconnect both battery terminals (negative first).
- Use a socket set to remove the battery hold-down clamp and lift the battery out safely.
3.2. Install New Battery
- Place the new battery in the tray and secure it with the hold-down clamp.
- Connect the positive (+) terminal first, followed by the negative (-) terminal.

4. Starter Motor Inspection

4.1. Check Connections
- Inspect the starter motor wiring for loose or damaged connections.
- Tighten any loose connections or replace damaged wiring.
4.2. Test Starter Motor
- If the battery is good, use the multimeter to test the voltage at the starter solenoid while a helper turns the ignition key to the start position.
- If there is no voltage, the ignition switch or wiring may be faulty.

5. Final Check

After replacing the battery or repairing any connections, attempt to start the vehicle again.
If the vehicle still does not start, the starter motor may need to be replaced.
