Solution

1. Preparation

Gather tools: Multimeter, socket set, OBD-II scanner, jumper cables.
Ensure the vehicle is parked on a level surface and the ignition is off.

2. Battery Inspection

Sub-step 1: Disconnect the negative battery terminal to ensure safety.
Sub-step 2: Clean any corrosion from the battery terminals and connections.
Sub-step 3: Reconnect the terminals securely and check voltage with a multimeter.

3. Starter Relay and Fuse Check

Sub-step 1: Locate the fuse box and check the starter fuse; replace if blown.
Sub-step 2: Test the starter relay by swapping it with a similar relay in the fuse box.

4. Ignition Switch Inspection

Sub-step 1: Remove the steering column cover to access the ignition switch.
Sub-step 2: Use a multimeter to check for continuity when the key is turned to the start position.
Sub-step 3: Replace the ignition switch if no continuity is detected.

5. Starter Motor Test

Sub-step 1: Locate the starter motor and disconnect its electrical connector.
Sub-step 2: Use jumper cables to directly power the starter motor; it should engage and crank the engine.
Sub-step 3: Replace the starter motor if it does not operate when powered directly.
