Solution

1. Preparation

Gather tools: Multimeter, OBD-II scanner, socket set, and torque wrench.
Ensure the vehicle is in park (or neutral for manual transmission) and the parking brake is engaged.

2. Battery Inspection and Replacement

Check Battery Voltage
- Use a multimeter to measure voltage across the battery terminals.
- If below 12.4V, proceed with charging or replacing the battery.
Clean Battery Terminals
- Disconnect the negative terminal first, followed by the positive terminal.
- Clean any corrosion using a battery terminal cleaner or a mixture of baking soda and water.
- Reconnect terminals, ensuring a snug fit.

3. Ignition Switch Replacement

Remove Steering Column Covers
- Use a socket set to remove screws securing the steering column covers.
- Carefully detach the covers to access the ignition switch.
Replace Ignition Switch
- Disconnect the wiring harness from the ignition switch.
- Remove the screws holding the ignition switch in place.
- Install the new ignition switch and reconnect the wiring harness.
- Reassemble the steering column covers.

4. Fuse Inspection and Replacement

Locate Fuse Box
- Open the fuse box located under the dashboard or in the engine compartment.
Inspect Relevant Fuses
- Identify and check fuses related to the starting system (refer to the owner's manual for location).
- Replace any blown fuses with new ones of the same amperage.
