Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, jumper cables
Disconnect the negative battery terminal to ensure safety.

2. Battery Inspection

Remove the battery from the vehicle.
Clean the battery terminals using a wire brush to remove any corrosion.
Charge the battery if the voltage is below 12.4 volts or replace it if faulty.

3. Starter Motor Testing

Locate the starter motor (typically near the engine block).
Disconnect the wiring harness and the battery cable from the starter.
Use a multimeter to check for voltage at the starter terminal while someone turns the ignition key to the start position.
- If voltage is present but the starter does not engage, the starter may need replacement.

4. Ignition System Check

Inspect the ignition switch for proper operation. Turn the key and observe if the dashboard lights respond.
If not functioning, replace the ignition switch.

5. Reassembly

Reconnect the battery terminals securely.
Ensure all components are reinstalled correctly and tight.
