Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, and safety gloves.
Ensure the vehicle is in park (automatic) or neutral (manual) and set the parking brake.
Disconnect the negative battery terminal to avoid electrical hazards.

2. Battery Inspection

Reconnect the battery and perform a load test on the battery using a load tester.
If the battery fails the load test, replace it with a new one of the same specifications.

3. Starter Relay and Connections

Locate the starter relay in the fuse box; remove it using a socket set.
Inspect the relay terminals for corrosion; clean if necessary.
If no issues are found, swap the relay with a similar one to test functionality.

4. Starter Replacement (if necessary)

Disconnect the battery negative terminal again for safety.
Locate the starter motor (usually found near the engine block).
Remove the wiring harness from the starter solenoid.
Unbolt the starter from its mount using the socket set (note torque specifications for reinstallation).
Install the new starter by reversing the removal steps and ensuring all connections are secure.

5. Final Checks

Reconnect the negative battery terminal.
Ensure all tools are removed from the engine bay.
Start the engine to confirm repair success.
