Solution

1. Preparation

Tools Required: Socket set, multimeter, OBD-II scanner, jumper cables
Ensure the vehicle is in a safe location and the parking brake is engaged.
Disconnect the battery by removing the negative terminal first to prevent short circuits.

2. Check Battery and Connections

Inspect battery terminals for corrosion; clean with a wire brush if necessary.
Tighten battery terminal connections.
Reconnect the battery, ensuring the negative terminal is connected last.

3. Test and Replace Battery (if necessary)

Measure the battery voltage using a multimeter.
- If below 12.6 volts, proceed to jump-start the vehicle.
If jump-starting is successful, let the vehicle run for 15-20 minutes to charge the battery.
If the vehicle does not start even after jump-starting, replace the battery.
- Remove the old battery using a socket set to undo the hold-down bracket and terminal connections.

4. Inspect and Replace the Starter Motor (if necessary)

If the battery is functional, remove the starter motor for inspection.
- Disconnect the positive terminal from the battery.
- Remove the starter motor electrical connections (usually a nut and a clip).
- Unbolt the starter from the engine (typically requires a socket set).
Test the starter using a multimeter to verify functionality.
If faulty, replace with a new or refurbished starter motor.
- Reinstall the starter, ensuring all connections are secure.
