Solution

1. Preparation

Gather tools: socket set, multimeter, jumper cables, flashlight.
Ensure the vehicle is in park (automatic) or neutral (manual) and the parking brake is engaged.

2. Battery Inspection

Sub-step 1: Disconnect the negative terminal of the battery using a socket wrench.
Sub-step 2: Clean the battery terminals and cable ends with a wire brush to remove any corrosion.
Sub-step 3: Reconnect the battery terminals securely.

3. Battery Testing

Sub-step 1: Connect a multimeter to the battery terminals (red to positive, black to negative).
Sub-step 2: Read the voltage; if below 12.6 volts, charge or replace the battery.
Sub-step 3: If the battery is good, proceed to the next steps.

4. Starter and Relay Inspection

Sub-step 1: Locate the starter motor under the vehicle, usually near the transmission.
Sub-step 2: Check the wiring harness and connections to the starter for any signs of damage or looseness.
Sub-step 3: Swap the starter relay with an identical one in the fuse box to test functionality.

5. Starter Replacement (if necessary)

Sub-step 1: If the starter is confirmed faulty, disconnect the battery again.
Sub-step 2: Remove the bolts securing the starter motor to the engine.
Sub-step 3: Disconnect the electrical connectors from the starter.
Sub-step 4: Install the new starter by reversing the removal procedure and ensure all connections are secure.
