Solution

1. Preparation

Gather tools: Multimeter, socket set, jumper cables, OBD-II scanner, and safety gloves.
Ensure the vehicle is in park (automatic) or neutral (manual) and the parking brake is engaged.

2. Battery Inspection

Disconnect the negative (-) battery terminal using a socket wrench.
Clean any corrosion from the terminals and cable ends with a wire brush.
Reconnect the battery terminal and ensure tight connections.

3. Battery Testing

Use a multimeter to measure the battery voltage; if below 12.4 volts, proceed to replace the battery.
If battery replacement is necessary, remove the battery with a socket set, ensuring to disconnect the positive (+) terminal first, followed by the negative (-) terminal.
Install the new battery by connecting the positive (+) terminal first, followed by the negative (-) terminal.

4. Starter Motor Inspection

If the battery is functional, locate the starter motor (typically found near the transmission bell housing).
Disconnect the wiring harness from the starter motor.
Using a socket set, remove the starter mounting bolts and carefully extract the starter motor.
Inspect the starter for signs of wear or damage, and test it by applying direct power from a battery.

5. Reinstallation

If the starter is functional, reinstall it by reversing the removal steps, ensuring all connections are secure and properly torqued to the manufacturer’s specifications.
If a new starter is needed, install it following the same procedure.
