Solution

1. Preparation

Gather tools: Multimeter, socket set, wrenches, safety gloves, and safety glasses.
Ensure the vehicle is in park with the parking brake engaged.
Disconnect the battery by removing the negative terminal first.

2. Battery Inspection

Clean Battery Terminals:
- Use a wire brush to clean any corrosion from the battery terminals and cable ends.
- Reconnect the terminals securely.
Battery Replacement (if necessary):
- If the battery voltage is below 12.4 volts after testing, consider replacing the battery.
- Remove the old battery by loosening the hold-down bracket and disconnecting the positive terminal first, followed by the negative terminal.
- Install the new battery by connecting the positive terminal first.

3. Starter Motor Testing

Inspect Starter Connections:
- Visually inspect the connections on the starter motor for damage or looseness.
- Tighten any loose connections and ensure no corrosion is present.
Starter Relay Replacement (if necessary):
- Locate the starter relay in the fuse box and test for continuity. Replace if faulty.

4. Reassembly

Reconnect the battery terminals, starting with the positive terminal followed by the negative terminal.
Ensure all connections are tight and secure.

5. Testing

Attempt to start the vehicle to check if the issue has been resolved.
