Solution

1. Preparation

Gather tools: multimeter, socket set, jumper wire, and cleaning brush.
Ensure the vehicle is in park or neutral with the parking brake engaged.
Disconnect the battery to prevent accidental electrical shorts.

2. Battery Inspection

Sub-step 1: Visually inspect battery terminals for corrosion. Clean with a wire brush if necessary.
Sub-step 2: Tighten the battery terminals to ensure a secure connection.
Sub-step 3: Test the battery voltage again; if below 12.4 volts, proceed to jump-start or replace the battery.

3. Starter Motor Check

Sub-step 1: Locate the starter motor and ensure it is securely mounted.
Sub-step 2: Disconnect the wiring harness from the starter motor.
Sub-step 3: Use a jumper wire to connect the positive terminal of the battery directly to the starter motor terminal. If the motor engages, it may need replacement.

4. Fuse and Relay Inspection

Sub-step 1: Locate the fuse box and remove the cover.
Sub-step 2: Identify and check the fuses related to the starting system; replace any blown fuses.
Sub-step 3: Test the starter relay by swapping it with a similar relay to see if the issue resolves.

5. Wiring Harness Inspection

Sub-step 1: Follow the wiring from the battery to the starter and inspect for frays or breaks.
Sub-step 2: Repair or replace any damaged wiring as necessary.
