Solution

1. Preparation

Gather tools and parts: multimeter, socket set, jumper cables, and replacement battery if necessary.
Ensure the vehicle is in park (automatic) or neutral (manual) and the parking brake is engaged.

2. Battery Inspection and Replacement

Locate the Battery: Open the hood and find the battery.
Check Battery Terminals:
- Use a wrench to loosen the negative (-) terminal and remove it.
- Clean any corrosion from the terminals using a wire brush.
- Reconnect the negative terminal and tighten securely.
Test Battery Voltage:
- Connect the multimeter to the battery terminals. If voltage is below 12.4 volts, proceed to replace the battery.
Remove Old Battery:
- Disconnect the positive (+) terminal first, then the negative (-).
- Remove the battery hold-down bracket using a socket set.
- Carefully lift out the old battery.
Install New Battery:
- Place the new battery in the battery tray.
- Reinstall the hold-down bracket and tighten.
- Connect the positive terminal first, then the negative terminal.

3. Starter Motor Inspection

Locate the Starter Motor: Typically found near the transmission on the engine block.
Check Connections:
- Visually inspect the wiring harness for frays or loose connections.
- Ensure all bolts and connections are tight.
Test the Starter:
- If accessible, use a multimeter to check for voltage at the starter terminal while someone attempts to start the car.
- If there is no voltage, the ignition switch or wiring may be faulty.
