Solution

1. Preparation

Tools Required: Socket set, multimeter, battery terminal cleaner, wrench set.
Ensure the vehicle is in a safe and well-ventilated area.
Disconnect the negative terminal of the battery before proceeding.

2. Battery Inspection

Check Battery Connections:
- Remove any corrosion from battery terminals using a battery terminal cleaner.
- Tighten any loose connections.
Test Battery Voltage:
- Connect a multimeter to the battery terminals.
- Ensure the voltage reading is above 12.4 volts. If below, the battery may need charging or replacement.

3. Battery Replacement (if necessary)

Remove Old Battery:
- Disconnect the negative terminal first, followed by the positive terminal.
- Remove any retaining brackets securing the battery.
Install New Battery:
- Position the new battery in the tray.
- Connect the positive terminal first, then the negative terminal.
- Ensure all connections are secure.

4. Starter System Check

Inspect Starter Relay:
- Locate the starter relay in the fuse box.
- Swap it with a similar relay to see if the issue resolves.
Test Starter Motor:
- If the relay swap didn’t work, tap the starter motor gently with a hammer while a helper turns the ignition key to start. This may indicate a stuck starter.

5. Final Checks

Reconnect the battery terminals if previously disconnected.
Ensure all tools and materials are removed from the engine bay.
