Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to avoid electrical shock.
Ensure vehicle is in park (or neutral) with the parking brake applied.

2. Battery Inspection and Replacement

Check Battery Voltage:
- Connect a multimeter to the battery terminals.
- If voltage is below 12.4V, charge the battery or replace it.
Clean Battery Terminals:
- Remove the battery terminals using a socket wrench.
- Clean terminals and battery posts with a wire brush and a baking soda solution to remove corrosion.
- Reattach terminals securely, ensuring tight connections.

3. Starter Motor Testing

Bypass Ignition:
- Locate the starter motor (usually near the transmission).
- Use a jumper wire to connect the positive terminal of the battery to the starter solenoid terminal.
- If the starter engages and the engine cranks, the ignition switch or key fob may be faulty.

4. Fuse and Wiring Inspection

Check Fuses:
- Locate the fuse box (refer to the owner's manual for location).
- Inspect the fuses related to the starter and replace any blown fuses.
Inspect Wiring:
- Check the wiring harness for signs of wear or damage leading to the starter and battery.
- Repair or replace any damaged wiring as necessary.

5. Reassemble and Test

Reconnect the battery terminal.
Attempt to start the vehicle again.
