Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, screwdriver set, battery terminal cleaner.
Disconnect the negative battery terminal to ensure safety while working on electrical components.
Allow the vehicle to cool down if it has been running prior to troubleshooting.

2. Battery Inspection

Remove the battery terminals (positive first, then negative).
Clean the terminals and ensure there are no signs of corrosion.
Reconnect the battery terminals securely.
Use a multimeter to check the battery voltage again; replace the battery if voltage is below 12.4 volts.

3. Starter Relay Check

Locate the starter relay in the fuse box (check the owner's manual for location).
Remove the relay and inspect for any signs of damage or overheating.
Use a multimeter to test the relay for continuity; replace if faulty.

4. Ignition Switch Testing

Remove the ignition switch cover using a screwdriver.
Inspect the ignition switch for any signs of wear or damage.
Test the switch with a multimeter; replace if it does not provide proper continuity.

5. Starter Motor Inspection

Locate the starter motor and check the wiring for loose connections or corrosion.
If the starter motor is accessible, check for proper voltage at the starter terminal when attempting to start the vehicle.
If voltage is present but the starter does not engage, replace the starter motor.
