Solution

1. Preparation

Gather necessary tools: multimeter, jumper cables, OBD-II scanner, socket set, and safety gloves.
Ensure the vehicle is in park (automatic) or neutral (manual) and the parking brake is engaged.

2. Battery Inspection and Replacement

Check Battery Condition
- Use the multimeter to measure the voltage.
- If below 12.4 volts, charge the battery fully.
- If the battery is old (over 3-5 years), consider replacing it.
Clean Battery Terminals
- Disconnect the negative terminal first, followed by the positive.
- Clean any corrosion using a wire brush and a mixture of baking soda and water.
- Reconnect terminals securely, starting with the positive terminal.

3. Starter Motor Testing and Replacement

Test Starter Motor
- Locate the starter motor; typically found near the engine block.
- Disconnect the wiring harness and the battery cable from the starter.
- Use jumper cables to apply power directly to the starter solenoid; if it engages, the starter is faulty.
Replace Starter Motor (if needed)
- Remove the starter motor mounting bolts using a socket set.
- Carefully take out the old starter motor and replace it with the new one.
- Reconnect the wiring harness and battery cable securely.

4. Fuse Inspection and Replacement

Check Starting System Fuses
- Locate the fuse box; refer to the owner’s manual for the specific fuse related to the starter.
- Inspect the fuse visually; if blown, replace it with a fuse of the same rating.
