Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, jumper wires, and safety gloves.
Ensure the vehicle is in park (or neutral if manual) and the parking brake is engaged.

2. Battery Inspection

Step 1: Disconnect the negative battery terminal using a socket wrench.
Step 2: Clean any corrosion from the terminals with a wire brush.
Step 3: Reconnect the battery terminal securely and check voltage again.

3. Starter Motor Testing

Step 1: Locate the starter motor (usually near the transmission).
Step 2: Disconnect the electrical connector from the starter.
Step 3: Use jumper wires to connect the battery directly to the starter motor to test its function. If it spins, the starter is functional; if not, replace the starter.

4. Ignition Switch Check

Step 1: Remove the plastic cover from the steering column to access the ignition switch.
Step 2: Use a multimeter to test for continuity at the ignition switch terminals while turning the key.
Step 3: Replace the ignition switch if continuity is not present in the start position.

5. Fuse Inspection

Step 1: Locate the fuse box (often under the dashboard or in the engine compartment).
Step 2: Identify and pull the fuses related to the starting system (check the owner’s manual for fuse locations).
Step 3: Inspect each fuse for continuity using a multimeter; replace any blown fuses with the same amperage.
