Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, battery terminal cleaner, jumper cables.
Ensure the vehicle is in park or neutral and the parking brake is engaged.
Disconnect the negative battery terminal to prevent electrical shock.

2. Inspect and Clean Battery Terminals

Use a battery terminal cleaner to remove corrosion from the battery terminals.
Tighten the battery terminal connections securely.
Reconnect the negative terminal and ensure it is snug.

3. Test and Replace Battery (if necessary)

Use a multimeter to measure the battery voltage; if it's below 12.4 volts, consider replacing the battery.
If the battery is faulty, remove the old battery by disconnecting the negative terminal first, followed by the positive terminal.
Install the new battery by connecting the positive terminal first, followed by the negative terminal.

4. Check and Replace Starter Relay

Locate the starter relay in the fuse box.
Remove the relay and inspect it for signs of damage.
If necessary, replace the relay with a new one.

5. Inspect the Starter Motor

Locate the starter motor and inspect the wiring connections.
Ensure that all connections are secure and free of corrosion.
If the starter motor is suspected to be faulty, remove it using a socket set and replace it with a new starter.
