Solution

1. Preparation

Gather tools: socket set, multimeter, jump starter.
Ensure the vehicle is in park or neutral and the parking brake is engaged.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Check and Clean Battery Connections

Reconnect the battery terminal if it was disconnected.
Use a wire brush to clean any corrosion from the battery terminals and cable ends.
Tighten the connections securely to ensure proper contact.

3. Test and Replace Battery

Use a multimeter to measure the battery voltage.
- If the voltage is below 12.4 volts, charge or replace the battery.
If the battery is over three years old or shows signs of failure, consider replacing it.

4. Inspect and Replace Starter Motor (if necessary)

Locate the starter motor (usually near the engine block).
Disconnect the wiring harness from the starter.
Remove the mounting bolts with a socket set and carefully take out the starter motor.
Install the new starter motor by reversing the removal steps, ensuring the bolts are torqued to manufacturer specifications.
