Solution

1. Preparation

Gather tools: multimeter, socket set, wrench set, jumper cables, and safety gloves.
Ensure the vehicle is in a safe, well-ventilated area and the parking brake is engaged.

2. Battery Inspection and Replacement

Check Battery Voltage
- Use a multimeter to measure the battery voltage.
- If the voltage is below 12.4V, proceed to charge or replace the battery.
Inspect Battery Connections
- Disconnect the negative (-) terminal first, followed by the positive (+) terminal.
- Clean any corrosion using a wire brush and apply a terminal protector.
- Reconnect terminals, ensuring they are tight.
Replace Battery (if necessary)
- Remove the old battery by loosening the mounting brackets.
- Install the new battery in reverse order, connecting the positive (+) terminal first, followed by the negative (-).

3. Starter System Inspection

Test Starter Relay
- Locate the starter relay in the fuse box.
- Swap it with a similar relay to test functionality.
Check Starter Motor
- Remove the starter motor wiring harness.
- Inspect for damage; if damaged, replace the wiring.
- If the starter still does not function, remove the starter motor for testing or replacement.

4. Final Checks

After performing repairs, ensure all connections are secure.
Reconnect the battery terminals (positive first, then negative).
Test the vehicle starting function.
