Solution

1. Preparation

Gather tools: multimeter, socket set, screwdriver set, and cleaning supplies.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the negative terminal of the battery to ensure safety.

2. Battery Inspection

Sub-step 1: Reconnect the battery terminal and check the voltage with a multimeter.
Sub-step 2: If voltage is low, charge the battery or replace it if necessary.
Sub-step 3: Clean the battery terminals with a wire brush to remove corrosion.

3. Starter Relay Testing

Sub-step 1: Locate the starter relay in the fuse box (consult owner's manual for location).
Sub-step 2: Remove the relay and visually inspect for any damage.
Sub-step 3: Swap with a known good relay to test functionality.

4. Starter Motor Testing

Sub-step 1: Locate the starter motor, usually found near the transmission.
Sub-step 2: Disconnect the electrical connector and test for power using a multimeter while someone turns the ignition key.
Sub-step 3: If there is no power, trace back to the ignition switch; if power is present, the starter motor may need replacement.

5. Final Assembly

Sub-step 1: Reconnect all components and battery terminals securely.
Sub-step 2: Ensure all tools are removed from the engine bay before starting the vehicle.
