Solution

1. Preparation

Gather tools: multimeter, socket set, screwdriver, and safety gloves.
Ensure the vehicle is in "Park" or "Neutral" and the parking brake is engaged.
Disconnect the negative battery terminal to prevent electrical shock.

2. Battery Inspection

Inspect battery terminals:
1. Clean the battery terminals with a wire brush if corroded.
2. Tighten any loose connections.
Test battery voltage:
1. Reconnect the negative terminal.
2. Use a multimeter to measure the voltage; replace the battery if below 12.4 volts.

3. Starter Relay Check

Locate the starter relay in the fuse box:
1. Remove the relay and visually inspect it for damage.
2. Swap it with a similar relay to check for functionality.

4. Starter Motor Assessment

Access the starter motor:
1. Remove any components obstructing access (like the air intake duct).
2. Disconnect the electrical connector from the starter motor.
Test the starter motor:
1. Use a jumper wire to connect the battery directly to the starter terminal.
2. If the motor does not engage, replace the starter motor.

5. Ignition Switch Inspection

Check the ignition switch:
1. Remove the steering column cover to access the ignition switch.
2. Inspect for signs of wear or damage; replace if necessary.
