Solution

1. Preparation

Gather Tools: OBD-II scanner, socket set, multimeter, inspection mirror, and a flashlight.
Safety Precautions: Ensure the vehicle is in park with the parking brake engaged. Disconnect the battery before working on electrical systems.

2. Address Battery and Connections

Check Battery Voltage: Use a multimeter to test the battery voltage. It should read around 12.6 volts or higher.
Clean Connections: If corrosion is present, clean the battery terminals and cable connections using a wire brush and a mixture of baking soda and water.

3. Change Engine Oil (if necessary)

Drain Old Oil: Place a drain pan under the oil pan, remove the drain plug, and allow the oil to fully drain.
Replace Oil Filter: Remove the old oil filter using an oil filter wrench, lubricate the rubber gasket on the new filter with new oil, and install it.
Refill with New Oil: Replace the drain plug and refill the engine with the manufacturer-recommended oil (5W-30 or as specified).

4. Inspect and Replace Starter Motor (if needed)

Remove Starter Motor: Disconnect the battery, then remove the starter motor by unbolting it from its mounting and disconnecting the electrical connectors.
Inspect for Damage: Check the starter gear and solenoid for wear or damage; replace the starter motor if any issues are found.
Reinstall Starter Motor: Bolt the new or inspected starter back in place and reconnect the electrical connectors.
