Solution

1. Preparation

Gather tools: multimeter, socket set, jumper cables, and safety gloves.
Ensure the vehicle is in park (automatic) or neutral (manual) and the parking brake is engaged.
Disconnect the negative battery cable to prevent electrical shock.

2. Battery Inspection

Inspect the battery terminals for corrosion. If present, clean with a wire brush or battery terminal cleaner.
Check the battery voltage using a multimeter. If it’s below 12.4 volts, consider charging or replacing the battery.
Reconnect the battery and ensure connections are tight.

3. Starter Motor Testing

Locate the starter motor (usually found near the transmission).
Disconnect the wiring harness from the starter.
Using a jumper wire, connect the positive terminal of the battery to the starter terminal. If the starter engages and turns the engine, it may need replacement.
If it does not engage, the starter is likely faulty.

4. Replace Faulty Components

If the battery is weak, replace it with a new one (ensure it matches OEM specifications).
If the starter is confirmed faulty, remove it by:
- Removing any securing bolts using a socket set (typically 10-15 mm).
- Detaching the wiring harness.
- Installing the new starter in reverse order, ensuring all connections are secure.
