Solution

1. Preparation

Gather tools and parts: OBD-II scanner, multimeter, socket set, jumper cables.
Ensure the vehicle is in park or neutral, and the parking brake is engaged.

2. Battery Check and Replacement

Sub-steps:
1. Disconnect the negative battery terminal using a wrench to prevent electrical shorts.
2. Clean the battery terminals with a wire brush if corrosion is present.
3. Reconnect the battery and test voltage again; replace the battery if below 12.4 volts.
4. If replacing, remove the old battery and install the new one, ensuring tight connections.

3. Starter Motor Inspection

Sub-steps:
1. Disconnect the starter motor wiring harness and remove bolts securing the starter.
2. Inspect the starter for signs of wear or damage; replace if necessary.
3. If the starter appears functional, reconnect and proceed to test the solenoid.

4. Ignition Switch and Wiring Check

Sub-steps:
1. Remove the steering column cover to access the ignition switch.
2. Test the ignition switch with a multimeter for continuity in the start position.
3. Replace the ignition switch if it fails to show continuity.

5. Final Assembly and Testing

Sub-steps:
1. Reassemble any components removed during inspection.
2. Reconnect the negative battery terminal securely.
3. Attempt to start the vehicle and observe for any unusual noises or behaviors.
