Solution

1. Preparation

Gather tools and parts needed for the repair.
Disconnect the negative battery terminal to ensure safety.
Tools Required: Socket set, multimeter, screwdriver, OBD-II scanner.

2. Inspect Battery Terminals

Check for corrosion on battery terminals.
- If corrosion is present, clean the terminals with a wire brush and a mixture of baking soda and water.
Ensure that battery terminals are tightened securely.
- Reconnect the negative terminal and test the start condition.

3. Replace Fuses

Locate the fuse box and identify the fuses related to the ignition and starting systems.
Remove any blown fuses and replace them with new fuses of the same amperage.
Tools Required: Fuse puller or small pliers.

4. Test Starter Motor

Locate the starter motor and check its connections.
Use a multimeter to check for battery voltage at the starter terminal while attempting to start the engine.
- If voltage is present and the starter does not engage, replace the starter motor.

5. Inspect Ignition Switch

Remove the steering column cover to access the ignition switch.
Test the ignition switch with a multimeter to ensure it is functioning properly.
- If faulty, replace the ignition switch.
