Solution

1. Preparation

Gather tools: socket set, multimeter, OBD-II scanner, and basic hand tools.
Ensure the vehicle is parked on a flat surface and the ignition is off.

2. Battery Inspection

Disconnect the negative terminal of the battery to prevent accidental shorting.
Clean any corrosion from the battery terminals using a wire brush.
Tighten the terminals securely and reconnect the negative terminal.
Measure the battery voltage with a multimeter; if below 12.4 volts, replace the battery.

3. Starter Testing

Locate the starter motor, usually found near the engine block.
Disconnect the electrical connector from the starter.
Use a multimeter to check for voltage at the starter terminal when the ignition is turned to the start position.
If there is no voltage, check the wiring and fuses leading to the starter.
If voltage is present, test the starter by applying direct battery power to the motor terminal. If it clicks but does not engage, replace the starter.

4. Relay and Fuse Check

Locate the fuse box and identify the starter relay and associated fuses.
Remove the starter relay and test it for continuity with a multimeter.
Replace the relay if it is faulty.
Check any related fuses and replace them if blown.
