Solution

1. Preparation

Gather tools: Multimeter, OBD-II scanner, socket set, screwdriver, safety gloves.
Disconnect the battery negative terminal to ensure safety during repairs.

2. Battery Inspection

Remove the battery terminals (negative first, then positive).
Clean any corrosion from the terminals and battery posts using a wire brush.
Reconnect the battery terminals securely.

3. Battery Testing

Use a multimeter to measure the battery voltage.
- If the voltage is below 12.4 volts, recharge or replace the battery.
- If above 12.4 volts, proceed to the next step.

4. Starter Motor Testing

Locate the starter motor, typically found near the bottom of the engine.
Disconnect the starter motor electrical connector.
Using jumper cables, connect the starter directly to the battery.
- Positive to the starter terminal and negative to the starter housing.
- If it does not engage, replace the starter motor.

5. Ignition Switch Inspection

Remove the steering column covers to access the ignition switch.
Inspect the switch for any signs of damage or wear.
If faulty, replace the ignition switch.
