Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is in a safe area and parked on a flat surface.
Disconnect the negative battery terminal to prevent electrical shock.

2. Inspect and Clean Battery Connections

Sub-steps:
- Remove the positive terminal first, followed by the negative terminal.
- Clean the terminals and battery posts with a wire brush to remove any corrosion.
- Reattach the terminals, connecting the positive first, then the negative.

3. Test and Replace Battery

Sub-steps:
- Reconnect the negative terminal and test the battery voltage again.
- If the voltage is low, jump-start the vehicle or replace the battery with a new one.
- Ensure the new battery is fully charged and securely mounted.

4. Inspect and Replace Starter Motor (if necessary)

Sub-steps:
- Remove any components obstructing access to the starter motor.
- Disconnect the electrical connectors from the starter motor.
- Remove the mounting bolts and take out the starter motor.
- Install the new starter motor by reversing the removal steps, ensuring all connections are tight.

5. Final Checks

Reconnect the battery terminals and ensure all tools are removed from the engine bay.
Attempt to start the vehicle to verify operation.
