Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is in park or neutral and the ignition is off.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Battery Inspection

Inspect the battery terminals:
- Clean any corrosion using a wire brush and a mixture of baking soda and water.
- Tighten any loose connections.
If the battery voltage is low, jump-start the vehicle or replace the battery if it’s faulty.

3. Starter Relay and Fuse Check

Locate the fuse box and identify the starter relay and associated fuses:
- Remove the starter relay and check for continuity using a multimeter.
- Replace with a known good relay if faulty.
- Inspect and replace any blown fuses related to the starting system.

4. Starter Motor Inspection

If the battery and relay are functional, proceed to the starter motor:
- Locate the starter motor under the vehicle.
- Disconnect the wiring harness from the starter.
- Remove the starter motor using a socket set (typically requires 10mm or 12mm sockets).
- Inspect the starter for physical damage or wear.
- If necessary, replace the starter with a new or refurbished unit.

5. Reassembly and Testing

Reinstall the starter motor and reconnect all wiring.
Reconnect the negative battery terminal.
Start the vehicle to verify functionality.
