Solution

1. Preparation

Gather tools: socket set, multimeter, jumper cables, and a wrench.
Ensure the vehicle is in park (automatic) or neutral (manual) and engage the parking brake.

2. Battery Inspection

Sub-step 1: Disconnect the negative terminal of the battery.
Sub-step 2: Clean the battery terminals with a wire brush if corrosion is present.
Sub-step 3: Reconnect the battery terminals securely.
Safety Warning: Always disconnect the battery before working on electrical systems.

3. Starter Motor Check

Sub-step 1: Locate the starter motor (usually near the transmission).
Sub-step 2: Disconnect the wiring harness from the starter motor.
Sub-step 3: Use a multimeter to test the battery voltage at the starter terminal while someone turns the key to the start position.
Sub-step 4: If voltage is present, replace the starter motor.

4. Fuse Inspection

Sub-step 1: Locate the fuse box (typically under the dashboard or in the engine bay).
Sub-step 2: Identify and inspect the starter-related fuses (refer to the owner's manual for specific locations).
Sub-step 3: Replace any blown fuses with the same amperage rating.

5. Ignition Switch Test

Sub-step 1: Remove the steering column cover to access the ignition switch.
Sub-step 2: Inspect the ignition switch for any signs of wear or damage.
Sub-step 3: Test the switch for continuity using a multimeter while turning the key.
