Solution

1. Preparation

Tools Required: Multimeter, socket set, OBD-II scanner, fuse tester, and basic hand tools.
Ensure the vehicle is in a safe and accessible area. Disconnect the negative battery terminal for safety.

2. Battery Inspection

Sub-steps:
1. Reconnect the battery terminal if disconnected and ensure the battery is charged.
2. Clean any corrosion from battery terminals using a mixture of baking soda and water.
3. Tighten the battery terminals securely.

3. Fuse Check

Sub-steps:
1. Locate the fuse box (refer to the owner's manual for location).
2. Use the fuse tester to check each fuse related to the starting system.
3. Replace any blown fuses with the same amperage rating.

4. Ignition Switch Replacement (if faulty)

Sub-steps:
1. Remove the steering column cover using a screwdriver.
2. Disconnect the wiring harness from the ignition switch.
3. Unbolt the ignition switch using the socket set.
4. Install the new ignition switch and reconnect the wiring harness.
5. Reassemble the steering column cover.

5. Starter Motor Testing

Sub-steps:
1. Locate the starter motor (usually near the engine block).
2. Disconnect the wiring harness from the starter.
3. Use a multimeter to check for voltage at the starter when the key is turned.
4. If no voltage is detected, the ignition switch or wiring may be faulty; otherwise, replace the starter motor.
