Solution

1. Preparation

Gather tools: multimeter, socket set, screwdrivers, jumper wire, and safety gloves.
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 battery terminal using a socket wrench.
Sub-step 2: Clean the terminals of any corrosion with a wire brush.
Sub-step 3: Reconnect the battery and check voltage again; replace the battery if it reads below 12.4 volts.

3. Starter Motor Test

Sub-step 1: Locate the starter motor, usually positioned near the transmission.
Sub-step 2: Disconnect the electrical connector from the starter.
Sub-step 3: Use a jumper wire to connect the positive terminal of the battery to the starter terminal; listen for cranking noise. If the motor does not crank, it may need replacement.

4. Relay and Fuse Inspection

Sub-step 1: Locate the fuse box and identify the starter relay and related fuses.
Sub-step 2: Replace any blown fuses with the same amperage rating.
Sub-step 3: Swap the starter relay with a similar relay (if available) to test functionality.

5. Reassembly and Final Checks

Sub-step 1: Reconnect all electrical connectors and ensure they are secure.
Sub-step 2: Reattach the battery terminals, starting with the positive.
Sub-step 3: Test the vehicle by attempting to start the engine.
