Solution

1. Preparation

Gather tools and parts needed: OBD-II scanner, multimeter, socket set, and a new battery (if needed).
Ensure the vehicle is in park or neutral (for automatic transmissions) and the ignition is off.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Battery Inspection and Replacement

Inspect Battery
- Check battery terminals for corrosion; clean if necessary using a wire brush and battery terminal cleaner.
- Tighten any loose connections.
Test Battery
- Reconnect the negative terminal.
- Use a multimeter to measure voltage; if below 12.4 volts, proceed to replacement.
Remove Old Battery
- Disconnect positive terminal first, followed by the negative terminal.
- Remove battery hold-down bracket using the socket set.
- Lift the battery out carefully (it can be heavy).
Install New Battery
- Place the new battery in the tray.
- Secure it with the hold-down bracket.
- Connect the positive terminal first, then the negative terminal.

3. Starter Motor Inspection

Access Starter Motor
- Locate the starter motor under the vehicle.
- Disconnect the wiring harness and the positive cable from the starter.
Test Starter
- Use the multimeter to check for voltage at the starter terminal when the ignition is turned to the start position.
- If voltage is present but the starter does not engage, replace the starter motor.
Install New Starter
- Position the new starter motor in place.
- Connect the positive cable and wiring harness securely.
- Reinstall any brackets or covers that were removed.
