Solution

1. Preparation

Gather tools: multimeter, socket set, wrenches, OBD-II scanner, and a battery charger.
Ensure the vehicle is in "Park" or "Neutral" for safety.

2. Battery Inspection and Replacement

Disconnect Battery:
- Use a wrench to disconnect the negative terminal first, followed by the positive terminal.
- Safety Warning: Always disconnect the battery before working on electrical systems.
Clean Battery Terminals:
- Inspect for corrosion and clean terminals with a wire brush and a mixture of baking soda and water if necessary.
Test Battery Voltage:
- Use a multimeter to check the battery voltage; if below 12.4 volts, charge the battery or replace it if it fails to hold a charge.
Reconnect Battery:
- Reconnect the positive terminal first, then the negative terminal.

3. Starter Motor Inspection

Access Starter Motor:
- Remove any necessary components to gain access to the starter motor, such as the air intake or shields.
Test Starter Motor:
- Using a jumper wire, connect the battery directly to the starter motor's terminal. If it engages, the starter is faulty and needs replacement.

4. Replace Faulty Components

Remove Starter Motor:
- Unscrew and detach the starter motor from its mounting using a socket set.
Install New Starter Motor:
- Position the new starter motor and secure it with screws, using specified torque values (usually around 30 ft-lbs, check manufacturer specs).
Reconnect Electrical Connections:
- Reconnect the electrical connectors to the new starter motor.
