Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, jumper cables.
Ensure the vehicle is in park (automatic) or neutral (manual) and the parking brake is engaged.
Disconnect the negative terminal of the battery for safety.

2. Battery Inspection

Check battery terminals:
- Clean any corrosion on the terminals using a wire brush.
- Ensure terminals are securely tightened.
Test battery voltage:
- Reconnect the battery and measure voltage with a multimeter.
- If voltage is below 12.4 volts, replace the battery.

3. Starter Motor and Solenoid

Access the starter:
- Raise the vehicle using jack stands and locate the starter motor.
Test starter solenoid:
- Use a multimeter to check for voltage at the solenoid when the key is turned to start.
- If no voltage is present, check wiring and ignition switch.
Remove and test starter:
- Unbolt the starter motor from its mounting.
- Bench test the starter with a direct battery connection to see if it engages.
- Replace the starter if it fails to operate.

4. Reassemble and Reconnect

Reinstall the starter and connect all wiring securely.
Reconnect the negative terminal of the battery.
Lower the vehicle and ensure all tools are removed from the engine bay.
