Solution

1. Preparation

Gather tools: multimeter, socket set, OBD-II scanner.
Ensure the vehicle is in park and the parking brake is engaged.
Disconnect the negative battery terminal to prevent electrical shock.

2. Battery Inspection

Sub-step 1: Remove the battery terminals (negative first, then positive).
Sub-step 2: Clean any corrosion from the terminals using a wire brush or battery terminal cleaner.
Sub-step 3: Reconnect the battery terminals, ensuring they are secure.

3. Starter Motor Testing

Sub-step 1: Locate the starter motor (typically found on the lower side of the engine).
Sub-step 2: Use a multimeter to measure voltage at the starter motor terminal while a helper turns the key to the start position.
Sub-step 3: If voltage is present but the starter does not engage, replace the starter motor.

4. Fuse Check

Sub-step 1: Access the fuse box (refer to the owner's manual for location).
Sub-step 2: Identify and inspect fuses associated with the ignition and starting system.
Sub-step 3: Replace any blown fuses with the correct amperage fuses.

5. Ignition Switch Inspection

Sub-step 1: Remove the steering column cover to access the ignition switch.
Sub-step 2: Test the ignition switch with a multimeter for continuity.
Sub-step 3: If faulty, replace the ignition switch.
