Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, torque wrench, and battery terminal cleaner.
Ensure the vehicle is in a well-ventilated area with the engine off and the keys removed from the ignition.

2. Battery Inspection

Disconnect the negative battery terminal using a socket wrench.
Clean any corrosion from the battery terminals and cable ends using a battery terminal cleaner.
Reconnect the battery terminal securely.

3. Starter Relay and Fuses

Locate the fuse box under the hood and remove the cover.
Check the starter relay and swap it with another relay of the same type to test functionality.
Inspect and replace any blown fuses related to the starting system as indicated in the vehicle's manual.

4. Starter Motor Testing

With the battery connected, locate the starter motor under the vehicle.
Use a multimeter to check for voltage at the starter motor's power terminal while attempting to start the vehicle.
If no voltage is present, trace the wiring back to the ignition switch and check for continuity.
If voltage is present but the starter does not engage, it may need to be replaced.

5. Final Steps

If the starter motor is faulty, remove it by disconnecting the electrical connectors and unbolting it from the engine mount.
Install the new starter motor by reversing the removal steps and ensuring all connections are tight.
