Solution

1. Preparation

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

2. Battery Inspection

Check Battery Condition:
- Use a multimeter to measure the voltage; if below 12.4 volts, charge or replace the battery.
Clean Terminals:
- Use a battery terminal cleaner to remove any corrosion on terminals. Ensure a clean connection.

3. Starter Relay and Fuse Check

Inspect Starter Relay:
- Locate the relay in the fuse box and swap it with a similar relay to test functionality.
Check Fuses:
- Locate the starter circuit fuse and replace it if it is blown. Use the owner’s manual to identify the correct fuse.

4. Starter Motor Inspection

Access Starter Motor:
- Remove any protective covers or shields to access the starter motor.
Check Wiring and Connections:
- Inspect the wiring harness to the starter for frayed or damaged wires. Tighten any loose connections.

5. Starter Motor Test

Bench Test Starter:
- If all previous checks are clear, remove the starter motor and bench test it by connecting it directly to a charged battery. If it does not engage, replace the starter motor.
