Solution

1. Preparation

Gather Tools: OBD-II scanner, multimeter, socket set, flashlight, and safety gloves.
Safety Warning: Disconnect the battery before performing any electrical work to avoid short circuits.

2. Battery Inspection

Sub-step 1: Remove the negative terminal from the battery using a socket wrench.
Sub-step 2: Clean any corrosion from the terminals using a wire brush.
Sub-step 3: Reconnect the negative terminal and ensure it is tight.

3. Voltage Check

Sub-step 1: Set the multimeter to the DC voltage setting.
Sub-step 2: Measure the voltage across the battery terminals. A healthy battery should read around 12.6 volts or higher.
Sub-step 3: If the voltage is low, charge the battery or replace it if it fails to hold a charge.

4. Starter Motor Testing

Sub-step 1: Locate the starter motor and inspect the wiring for damage or loose connections.
Sub-step 2: Connect a jumper wire to the starter solenoid terminal and the positive battery terminal to test if the starter engages.
Sub-step 3: If the starter engages, it may indicate a faulty ignition switch or neutral safety switch.

5. Fuse Check

Sub-step 1: Locate the fuse panel and identify the fuses related to the starting system.
Sub-step 2: Remove and inspect each fuse for continuity using a multimeter.
Sub-step 3: Replace any blown fuses with the same amperage rating.
