Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, wrench set, socket set, and safety gloves.
Ensure the vehicle is in a safe location and the engine is off. Disconnect the battery to prevent accidental short circuits.

2. Battery Replacement (if necessary)

Remove Battery Terminals:
- Use a wrench to loosen the negative terminal first, then the positive terminal.
- Remove the battery from the tray.
Install New Battery:
- Place the new battery in the tray and secure it using the hold-down clamp.
- Connect the positive terminal first, followed by the negative terminal.
Check Battery Health:
- Use a multimeter to ensure the new battery reads around 12.6 volts.

3. Starter Inspection and Replacement (if necessary)

Remove Starter:
- Disconnect the battery again.
- Locate the starter motor, typically near the transmission.
- Unbolt and remove any electrical connectors.
Install New Starter:
- Position the new starter in place, reconnect electrical connectors, and secure it with bolts to the transmission.
Reconnect Battery:
- Reconnect the battery terminals, starting with the positive terminal.

4. Oil Change (if necessary)

Drain Old Engine Oil:
- Place a drain pan under the oil pan and remove the drain plug to let the oil drain completely.
Replace Oil Filter:
- Remove the old oil filter using an oil filter wrench and install a new one, ensuring a proper seal.
Add New Oil:
- Reinstall the drain plug and fill the engine with the appropriate viscosity oil for cold weather (check owner’s manual).
