Solution

1. Preparation

Gather tools and materials: multimeter, socket set, jumper cables, and a new battery (if needed).
Ensure the vehicle is in park (automatic) or neutral (manual) and the parking brake is engaged.

2. Battery Inspection

Check Battery Voltage: Use a multimeter to measure the battery voltage; it should read at least 12.4 volts.
Clean Terminals: Disconnect the battery terminals (negative first), clean any corrosion with a wire brush, and reconnect securely.

3. Starter Relay and Fuse Check

Inspect Fuses: Open the fuse box and locate the starter and ignition fuses. Replace any blown fuses.
Test Starter Relay: Swap the starter relay with another relay of the same type in the fuse box to see if the issue resolves.

4. Jump-Start the Vehicle

Connect Jumper Cables: Connect the red jumper cable to the positive terminal of the dead battery and the other end to the positive terminal of the good battery. Connect the black cable to the negative terminal of the good battery and the other end to a metal ground on the vehicle with the dead battery.
Start Vehicle: Attempt to start the vehicle. If it starts, the battery may need replacement.

5. Replace the Battery or Starter Motor

Battery Replacement: If the battery is found to be faulty, replace it with a new one of the same specifications.
Starter Motor Replacement: If the vehicle still does not start, and the battery is good, remove the starter motor and replace it if it is found to be defective.
