Solution

1. Preparation

Gather tools and parts required for the repair.
Disconnect the battery to ensure safety while working on electrical components.
Tools Required: Socket set, wrench set, multimeter, OBD-II scanner.

2. Clean Battery Terminals

Remove the battery cables, starting with the negative terminal followed by the positive terminal.
Inspect terminals for corrosion; if present, clean them using a wire brush and a mixture of baking soda and water.
Reattach the cables securely, ensuring a tight fit.

3. Test and Replace Battery (if needed)

Using the multimeter, check the battery voltage.
- If the voltage is below 12.4 volts, charge the battery or replace it if it cannot hold a charge.
To replace:
1. Remove the old battery by unbolting it from the tray.
2. Install the new battery, ensuring it is secured properly.
3. Reconnect the positive terminal first, followed by the negative.

4. Inspect and Replace Starter Motor (if needed)

If the battery is functional, locate the starter motor.
Disconnect the electrical connectors and remove the bolts securing the starter.
Replace with a new starter motor if the old one is defective.
Reinstall the starter motor and reconnect electrical connectors.
