Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, wire brush, battery terminal cleaner.
Safety Warnings: Disconnect the battery before working on electrical systems. Wear safety goggles and gloves.

2. Address Battery Issues

Inspect and Clean Battery Terminals:
1. Disconnect the negative terminal first, then the positive terminal.
2. Clean terminals and battery posts using a wire brush and terminal cleaner.
3. Reconnect the positive terminal first, then the negative terminal.
Test and Replace Battery (if necessary):
1. If battery voltage is below 12.4 volts, charge the battery using a battery charger.
2. If the battery fails to hold charge after charging, replace it with a new battery compatible with the XC60.

3. Identify and Fix Parasitic Draw

Measure Parasitic Draw:
1. With the vehicle off, disconnect the negative battery terminal.
2. Connect the multimeter in series between the negative cable and the negative terminal.
3. Check the reading; it should be below 50 mA. If it's higher, proceed to the next step.
Locate the Source:
1. Remove fuses one by one while monitoring the multimeter reading to find the circuit causing excessive draw.
2. Once identified, repair or replace the faulty component or circuit.

4. Inspect and Repair Charging System

Test Alternator Output:
1. Start the vehicle and measure the voltage at the battery terminals.
2. If the reading is below 13.7 volts, inspect the alternator wiring and connections.
3. Replace the alternator if it’s not functioning properly.
