Solution

1. Preparation

Gather necessary tools and safety equipment.
Ensure the vehicle is in park or neutral with the parking brake engaged.
Disconnect the negative battery terminal to prevent electrical shocks.

2. Battery Inspection

Use a socket set to remove the battery terminals, starting with the negative terminal.
Clean any corrosion from the battery posts and terminals using a wire brush.
Reconnect the battery terminals securely, ensuring a tight fit.

3. Starter Relay Replacement (if needed)

Locate the starter relay in the fuse box (consult the owner's manual for the exact location).
Remove the relay by pulling it straight out of the socket.
Insert a new starter relay into the same socket firmly.

4. Starter Motor Inspection

Reconnect the negative battery terminal before proceeding.
Locate the starter motor (typically situated near the transmission).
Inspect the electrical connections to the starter motor for looseness or damage.
Tighten any loose connections and replace any damaged wiring.

5. Battery Replacement (if necessary)

If the battery is found to be defective, remove it using a socket set.
Install a new battery, ensuring it is secured and the terminals are connected correctly (positive first, then negative).
Re-check all connections for tightness.
