Solution

1. Preparation

Gather tools: multimeter, socket set, jumper cables, OBD-II scanner.
Ensure the vehicle is in park (automatic) or neutral (manual).
Wear safety gloves and goggles.

2. Battery Inspection

Sub-steps:
1. Disconnect the negative (-) battery terminal using a socket wrench.
2. Clean any corrosion on the battery terminals with a wire brush.
3. Reconnect the terminals and ensure they are securely tightened.

3. Starter Relay Check

Sub-steps:
1. Locate the under-hood fuse box and remove the cover.
2. Identify the starter relay and remove it.
3. Swap it with a similar relay (e.g., horn relay) to test functionality.
4. Reinstall the original relay if necessary.

4. Starter Motor Testing

Sub-steps:
1. Locate the starter motor under the vehicle (may require jacking up).
2. Check the wiring and connections for any signs of wear or damage.
3. Use a multimeter to check for power at the starter motor when the key is turned to the start position.
4. If no power is detected, further investigate the ignition switch or wiring.

5. Jump-Start (if needed)

Sub-steps:
1. Position a functioning vehicle close to the XC60.
2. Connect jumper cables: positive to positive, negative to negative.
3. Start the functioning vehicle and then attempt to start the XC60.
4. If it starts, allow it to run for a while to charge the battery.
