Solution

1. Preparation

Gather tools: multimeter, socket set, screwdriver set, OBD-II scanner, and a battery charger if needed.
Ensure safety: disconnect the negative battery terminal to prevent electrical shorts.

2. Battery Maintenance

Clean Battery Terminals
- Remove the battery terminals using a socket wrench.
- Clean the terminals and connectors with a wire brush to remove corrosion.
- Reattach the terminals securely.
Charge or Replace Battery
- If the battery voltage is low, connect a battery charger and charge it fully.
- If the battery is old (over 3-5 years), consider replacing it with a new one.

3. Starter Motor Inspection

Remove Starter Motor
- Locate the starter motor, typically near the bottom of the engine block.
- Disconnect any wiring harnesses connected to the starter.
- Remove the mounting bolts using a socket set and carefully pull the starter out.
Test Starter Function
- Connect the starter directly to a charged battery (use jumper cables for testing).
- Observe if the starter engages and spins. If not, replace the starter.

4. Ignition Switch and Relay Check

Inspect Ignition Switch
- Remove the steering column covers to access the ignition switch.
- Use a multimeter to test for continuity when the key is turned to the start position. Replace if faulty.
Examine Starter Relay
- Locate the starter relay in the fuse box.
- Swap it with a similar relay (if available) and test for starting functionality.
