Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, wrench set, battery terminal cleaner, and safety gloves.
Disconnect the battery by removing the negative terminal first.

2. Battery Inspection and Replacement

Sub-step 1: Clean battery terminals using a battery terminal cleaner to remove corrosion.
Sub-step 2: If the battery voltage is below 12.4 volts or it fails to hold a charge, replace the battery with one rated for cold cranking amps suitable for the XC60.
Sub-step 3: Reconnect the battery, ensuring tight connections.

3. Fuel System Check

Sub-step 1: Access the fuel pump relay; ensure it is functioning properly by replacing it if necessary.
Sub-step 2: If the fuel pump is not working, replace the fuel pump.
Sub-step 3: If fuel pressure is low, check the fuel filter and replace it if it is clogged.

4. Engine Oil Inspection

Sub-step 1: Check the engine oil level and viscosity; replace with the correct oil grade for cold weather, typically 0W-20 or 5W-30.
Sub-step 2: Ensure the oil is filled to the recommended level.

5. Starter Motor Check

Sub-step 1: Remove the starter motor for inspection.
Sub-step 2: Test the starter motor by connecting it directly to a power source to verify its operation; replace if faulty.
Sub-step 3: Reinstall the starter motor, ensuring all connections are secure.
