Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is in park (automatic) or neutral (manual).
Disconnect the negative battery terminal to avoid electrical shock.

2. Battery Inspection and Replacement

Remove Battery Terminals
- Loosen the negative terminal first, followed by the positive terminal.
- Remove the battery from the vehicle.
Test or Replace Battery
- If the battery is under 12.4 volts and fails the load test, replace it with a new battery compatible with the Volvo XC60.
- Install the new battery, connecting the positive terminal first, then the negative terminal.
Secure Battery
- Ensure the battery is properly secured in the battery tray.

3. Starter Motor Inspection

Access the Starter Motor
- Remove any necessary components obstructing access to the starter motor (e.g., engine covers, heat shields).
Inspect Connections
- Check the large power cable and smaller signal wire connected to the starter for tightness and corrosion.
Test Starter Motor
- If the connections are good, test the starter motor by applying direct battery voltage to the terminal. If it does not engage, replace the starter motor.

4. Relay and Fuse Check

Locate the Starter Relay
- Refer to the owner's manual for the location of the starter relay in the fuse box.
Inspect Relay
- Swap the starter relay with another identical relay in the fuse box to check for functionality.
- If the vehicle starts with the swapped relay, replace the faulty relay.
