Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, battery load tester, socket set.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.

2. Battery Inspection and Replacement

Check Battery Terminals:
1. Disconnect the negative terminal first, followed by the positive terminal to avoid short circuits.
2. Clean any corrosion from terminals and cable ends using a wire brush.
Test and Replace Battery if Necessary:
1. Use a multimeter to check for voltage; if below 12.4V, proceed with a load test.
2. If the battery fails the load test, remove the battery by unbolting the hold-down clamps and lifting it out.
3. Replace with a new battery of the same specifications (usually Group 48 for XC60).
4. Reconnect the positive terminal first, then the negative terminal.

3. Starter Motor Inspection

Check Starter Connections:
1. Locate the starter motor (usually near the transmission).
2. Inspect the electrical connections; ensure they are tight and free of corrosion.
Test Starter Motor:
1. Use a multimeter to check for voltage at the starter terminal while attempting to crank the engine.
2. If no voltage is present, check wiring from the ignition switch to the starter.
3. If voltage is present but the starter does not engage, replace the starter motor.
