Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, torque wrench, jumper cables.
Ensure the vehicle is parked on a level surface and the ignition is off. Disconnect the battery before proceeding with any electrical work.

2. Battery Inspection

Remove the battery terminals (negative first, then positive).
Clean any corrosion from terminals and cable ends using a wire brush.
Reconnect battery terminals securely (positive first, then negative).
Use a multimeter to test the voltage; replace the battery if voltage is below 12.4 volts.

3. Starter Relay and Fuse Check

Locate the fuse box under the hood and find the starter relay.
Remove the relay and inspect it visually for damage.
Swap with a similar relay to test functionality.
Check the fuses in the same circuit; replace any blown fuses with the same amperage.

4. Starter Motor Inspection

Locate the starter motor, typically found near the engine block.
Inspect wiring and connectors for damage or looseness.
If necessary, remove the starter motor by unbolting it from the engine, using a socket set.
Test the starter motor function by applying direct power from the battery to the motor terminals. If it does not engage, replace the starter motor.
