Solution

1. Preparation

Gather tools: Multimeter, socket set, OBD-II scanner, torque wrench, and safety gloves.
Ensure the vehicle is parked on a level surface and the ignition is off.

2. Battery Inspection and Maintenance

Sub-step 1: Disconnect the negative battery terminal using a socket set.
Sub-step 2: Clean the battery terminals and connectors with a wire brush to remove corrosion.
Sub-step 3: Reconnect the battery terminal securely and check voltage again.

3. Starter Relay Check

Sub-step 1: Locate the starter relay in the fuse box using the vehicle's manual.
Sub-step 2: Remove the relay and visually inspect for any damage.
Sub-step 3: Swap the starter relay with another relay of the same type from the fuse box to test functionality.

4. Starter Motor Inspection

Sub-step 1: Locate the starter motor, typically found near the engine block.
Sub-step 2: Check the wiring and connections for wear or damage.
Sub-step 3: Use a multimeter to test for voltage at the starter motor while attempting to start the vehicle.
Sub-step 4: If the starter is faulty, remove it using a socket set, replacing it with a new or refurbished starter motor.
